TLRFULL is the new electronic control board designed to fully manage hot-water pressure washers. A microprocessor handles all functions and allows easy, customizable configuration through the TesterTLR software, compatible with Windows PCs.

Main functions

• Custom configuration: timing, feature enabling/disabling, and hour-meter readings (total and partial) can be adjusted directly from the software.
• Traceability: each board is programmed with a unique serial number, visible in the software, ensuring full equipment traceability.
• Smart spark control: ignition is activated only when needed and automatically disabled when the flame is detected, increasing igniter lifespan.
• Universal power supply: operates from 90 to 520 Vac (50/60 Hz) with automatic voltage detection and no manual adjustments.
• Advanced hour-meter: logs operating hours (hot and cold), thermal-protection events, and includes a maintenance counter. The manufacturer can choose whether the machine continues to operate or stops once the threshold is exceeded.
• Hour-meter reset: a dedicated button (software-enabled) allows the operator to reset the partial counter after maintenance.

Integrated safety features

• Motor thermal protection: if the thermal pad on the pump motor trips, the board shuts down the machine and signals the fault. Normal operation resumes automatically once temperature returns to safe levels.
• Photocell monitoring: ensures operator and machine safety. Any tampering, failure, or breakage disables the heating system. Only the manufacturer can override this protection via software.

Customization via TesterTLR

• Adjust timing parameters and safety thresholds.
• Invert or disable input controls.
• View the serial number for traceability.

Configurable functions

• TotalStop activation delay at startup and trigger release.
• Maximum continuous pump runtime limit.

• Water-loss detection.
• Flame-loss detection.
• Diesel-loss detection.
• Smoke-fan shutdown timing.
• Maintenance reminder.
• Machine lockout for missed maintenance.
• Anti-scale activation at regular intervals (counting only when the pump is running).

Hardware features

• Power connections via 6.3 mm Faston terminals.
• Control and command via Phoenix plug-in terminals.
• Outputs:
  • Pump motor: 3 × 40A relays.

The new TLR15 has been designed specifically for the management and control of cold-water pressure washers, extending the range of supported power levels. The board operates as a simple timer for pump-motor control, with a standard timing of 15 seconds.

The TLR15 is fully microprocessor-controlled and can be configured directly by the operator using the test interface and the TesterTLR software for Windows PCs. Each unit is serialized (serial number visible via software), ensuring complete traceability.

The operator can configure timings, enable or disable specific functions, and monitor both total and partial hour-meters. The board includes a 24 Vac output whose function can be selected via software:

• External hour-meter mode: activates in parallel with the pump, typically used to drive an external hour-meter.
• Indicator mode: provides specific warning signals through coded blinking patterns.

The TLR15 also integrates an internal hour-meter, visible via software, enabling advanced maintenance management. A key feature is the partial hour-meter for maintenance alerts: once the configured threshold is reached, the board signals the need for routine service (resettable only via software). The operator can define whether the machine should continue operating normally or be completely shut down after an additional time threshold. All functions are fully configurable and can be disabled through TesterTLR.

The TLR15 includes a low-voltage input for connecting one or more switches in series, allowing complete shutdown of the electronic section.

Main Operational Features

• Pump motor output driven internally by 3 separate relays
• Electronics fully encapsulated in epoxy resin for dust and moisture protection

The new TLR20 has been designed specifically for the management and control of cold-water pressure washers, extending the supported power range within the TLR family. This version is equipped with dedicated power and control wiring to fully utilize the relay current capacity, which is not achievable with the Faston connectors used on the TLR15.

The board operates as a timer for pump-motor control, with a standard delay of 15 seconds (modifiable via software). The TLR20 is fully microprocessor-controlled and can be configured directly by the operator using the TesterTLR software on Windows PCs.

Each unit is serialized (serial number visible via software), ensuring full traceability. Timing parameters, function enabling/disabling, and both total and partial hour-meters can be configured through the software.

24 Vac Configurable Output

The board includes a 24 Vac output (max 100 mA), whose function can be selected via software:

• External hour-meter mode — activates in parallel with the pump, typically used to drive an external hour-meter (available on request)
• Indicator mode — provides specific warning signals through blinking patterns

Maintenance Management

The TLR20 integrates an internal hour-meter, visible via software, enabling advanced maintenance scheduling. A partial hour-meter is available for maintenance alerts: once the configured threshold is reached, the board signals the need for routine maintenance. Reset can be performed exclusively via software.

The operator can define the board’s behavior when the threshold is reached:

• Continue normal operation
• Completely shut down the machine after a second configurable threshold

All functions can be configured or disabled through the TesterTLR software.

Alarm Descriptions (Indicator Mode Active)

• Steady ON — Total lockout due to missed maintenance (reset by service center)
• 1 blink — Recommended maintenance warning (reset by service center)
• 2 blinks — Pump always active (remove power for a few seconds to restore operation)
• 3 blinks — Micro-leaks / false starts (remove power for a few seconds to restore operation)
• 4 blinks — Inactivity lockout (remove power for a few seconds to restore operation)

The TLRF‑EC is a microprocessor‑controlled module designed for cold‑water pressure washers, expanding the range of compatible control units. Configuration is performed via the TesterTLR software (PC‑configurable), allowing full access to timing parameters, function enabling, and both total and partial hour‑meters.

Each unit is serialized (serial number visible through software), ensuring complete traceability. The board includes an integrated reset button (plus external reset input). When enabled via software, it allows the end user to reset the maintenance counter.

Maintenance management

A dedicated LED output signals when ordinary maintenance is required. The behavior at threshold is fully configurable:

• [Reset enabled](ca://s?q=Explain_reset_enabled_TLRF_EC) — the end user can reset the maintenance counter via the reset button.
• [Unlimited operation](ca://s?q=Explain_unlimited_operation_TLRF_EC) — the machine continues operating while signaling maintenance; reset is possible only via software.
• [Dual‑threshold lock](ca://s?q=Explain_dual_threshold_lock_TLRF_EC) — after exceeding the second threshold, the board enters lock mode; unlock is possible exclusively via software.

The TLRF‑EC is designed for use with an external contactor (available from us), allowing the same control unit to be used across the entire cold‑water machine range.

Motor thermal protection

The motor‑thermal input blocks the machine when the operating temperature is exceeded and signals the event via LED. A different blinking pattern indicates the return to normal temperature. Power‑cycling the machine after a few seconds restores normal operation. All thermal events are logged through a dedicated counter.

Operating characteristics

• 10 A relay output with clean NO contacts for external contactor.
• Quick‑connect terminal blocks for fast installation.
• Tropicalized PCB for moisture protection.

• LED 1 + LED 2 blinking 2 s / 2 s — pump lock due to continuous operation
• LED 2 steady ON — ordinary maintenance warning
• LED 1 + LED 2 blinking 0.3 s / 0.3 s — water‑loss alarm
• LED 1 + LED 2 blinking 1 s / 1 s — micro‑leak / false‑start alarm
• LED 1 + LED 2 alternating 0.5 s / 0.5 s — high pump‑motor temperature
• LED 1 + LED 2 alternating 2 s / 2 s — temperature restored

The TLR11CNT is the evolution of the standard TLR11 model, now fully microprocessor-controlled, enabling the integration of new advanced functions. The board includes a connector that, through a dedicated interface board , allows connection to a PC. Using the TesterTLR software , the user can configure timings, enable or disable functions and controls, test each input/output individually, and monitor machine status during operation. Each unit is serialized (serial number visible via software), ensuring full traceability.

A key additional feature is the hour-meter, which displays total operating hours and hours worked with hot water. A maintenance hour-meter is also included: once the preset threshold is reached, a dedicated warning is shown (resettable only via software). The manufacturer can choose whether the machine continues operating or stops completely after an additional time threshold. All functions can be configured or disabled through TesterTLR.

The TLR11CNT is equipped with the new universal power supply system, allowing direct connection to any voltage between 90 and 520 Vac (50/60 Hz) without manual adjustments. The board automatically detects and adapts to the input voltage.

The unit includes a clean-contact NO relay, typically used for the 3-second delayed activation of the diesel solenoid valve. A low-voltage switch can also be connected to completely disable the electronic section of the board.

The TLR11CNT provides 4 pressure-switch inputs, which also act as safety controls: in case of water shortage, the diesel solenoid valve is immediately disabled and the pump stops after the configured TotalStop delay.

Additional controls include micro-leak detection, inactivity lockout, and continuous-operation lockout, each with dedicated alarm signaling.

Operational characteristics

• Pump motor output driven internally by 3 relays.
• Electronics encapsulated in epoxy resin for dust and moisture protection.

The new product has been designed specifically for the management and control of cold-water pressure washers and will replace and standardize the FLW models. It features the new universal power-supply system, allowing operation from 90 to 520 Vac, 50/60 Hz without any configuration. The board automatically detects the input voltage and adapts accordingly. The same supply voltage powers both the electronics and the pump.

The TLR includes an optional direct input that can be used to shut down the machine by wiring in series a main switch, emergency stop, motor thermal probe, or similar safety device.

It operates as a simple timer for pump-motor control, with a standard timing of 7 seconds (other timings available on request). Unlike other TLR models, the AF version does not perform the initial TOTALSTOP pressurization cycle: the pump activates only when the pressure-switch inputs are actually closed.

Operational Features

• Pump motor output driven internally by 3 separate relays
• Power-off input for complete machine shutdown
• Electronics fully encapsulated in epoxy resin for dust and moisture protection

The new TLR 4 EEP, fully microprocessor-controlled, ensures stable timing and integrates a universal power-supply system capable of operating from 90 to 520 Vac, 50/60 Hz without requiring configuration. The board automatically detects the input voltage and adapts accordingly. The same supply voltage powers both the electronics and the pump.

The product is designed specifically for the management and control of pressure washers equipped with a boiler for hot-water operation. Developed to keep costs low while still offering microprocessor-based control, the TLR 4 EEP includes additional functions not available on TLR4 FC models. Although it has no error-indicator LEDs, it allows the customer to choose timings and enable or disable functions at the time of purchase.

Factory Default Settings

• TOTAL STOP: 13 seconds
• Diesel solenoid valve delay: 3 seconds
• Micro-leak control: enabled (lockout after 10 micro-leaks within 12 seconds)
• Water shortage: enabled (total lockout after 12 seconds)
• Inactivity lockout: enabled (1 hour)
• Continuous-use lockout (pump always active): disabled

After an alarm is triggered, switching the unit off for a few seconds restores normal operation. The board includes an internal NO clean-contact relay for delayed activation of the diesel solenoid valve. A low-voltage switch may also be connected to completely shut down the electronic section.

This new version maintains the same numbering and wiring layout as the standard model, ensuring compatibility and easy replacement.

Operational Features

• Electronics fully encapsulated in epoxy resin for dust and moisture protection

The TLR 4 FTC represents the evolution of the standard TLR4FC model, now fully microprocessor-controlled, enabling the integration of advanced monitoring and control functions. The board includes a dedicated connector that, through the appropriate interface, allows connection to a PC. Using the TesterTLR software, the operator can:

• Set custom timings
• Enable or disable functions and safety controls
• Individually test each input and output
• Monitor machine status during operation

Each unit is serialized (serial number visible via software), ensuring full traceability. Additional integrated functions include an hour-meter displaying:

• Total operating hours
• Operating hours in hot-water mode

A maintenance hour-meter is also included: once the configured threshold is reached, the board signals the need for routine maintenance through a dedicated output. Reset can be performed exclusively via software. The operator can define the board’s behavior when the threshold is reached:

• Continue normal operation
• Completely shut down the machine after a second defined threshold

All functions can be configured or disabled through the TesterTLR software. The TLR 4 FTC integrates flame-control photocell monitoring and a dedicated thermostat input, ensuring safety of the heating circuit. Faults, tampering, or missing signals trigger a hot-circuit shutdown. Disabling this function is allowed only via software.

Dimensions remain identical to the TLR 4 FC model. To maintain the same footprint, internal wiring uses cables due to limited internal space. The model is not available in alternative versions; different solutions may require designing a new board, resin-sealed or open-frame, with different connection types.

The FTC unit is an additional safety board designed for flame-presence control in the pressure washer’s boiler. A standard commercially available photoresistor (not supplied) must be installed inside the boiler to detect the flame. In case of short circuit or interruption of the photoresistor, the board will enter lockout mode and signal the fault through the indicator light.

The FTC board is designed to be connected in series—inserted into the ignition circuit of the diesel solenoid valve like a simple switch. The selected FTC model must match the supply voltage of the solenoid valve used.

When powered, the board allows the solenoid valve to activate almost instantly, with the indicator light showing steady ON to confirm normal operation. From this moment, flame detection begins: if the flame is not detected or is lost for 5 continuous seconds, the FTC board cuts power to the solenoid valve, preventing diesel from entering the system and avoiding boiler clogging. The fault is signaled through a blinking indicator.

This condition persists as long as the FTC remains powered. When power is removed, the board resets (indicator OFF). Once power is restored, normal operation resumes with active flame monitoring.

Available Power-Supply Versions

• FTC12 — 12 Vac
• FTC24 — 24 Vac
• FTC230 — 90–250 Vac

Operational Features

• Connections via FS17 colored cables, approx. 18 cm length
• Electronics fully encapsulated in epoxy resin for dust and moisture protection

The TMA24 unit is a simple yet highly useful timer, adjustable between 5 and 55 seconds through an external 100 kΩ potentiometer/trimmer (not supplied as standard; available on request). When the push-button input is closed, the board begins counting the preset time. Once the delay is reached, the relay activates by opening its contacts, permanently disabling the connected load.

Power must be removed for a few seconds to restore operation. If the push-button input opens before the preset delay is reached, the timer resets and the count restarts from zero.

On request, a fixed-time version (non-adjustable) can be supplied, with the timing set internally.

Operational Features

• Connections via FS17 colored cables, approx. 18 cm length
• Electronics fully encapsulated in epoxy resin for dust and moisture protection

The product is a simple 230 Vac delay module preset to 3 seconds. It is mainly used to delay the activation of the diesel solenoid valve, or in any application where a short delay is required. It is connected in series with the system (like a basic switch): once the circuit is powered, after 3 seconds the relay closes and activates the connected load, remaining active until power is removed, which resets the timer.

Versions with different supply voltages are available on request:

• RTD24 — 24 Vac
• RTD12 — 12 Vac

Operational Features

• Electronics fully encapsulated in epoxy resin for dust and moisture protection

The RTV230 is a simple delay module with both supply and output at 230 Vac. It is preset to delay the activation of the diesel solenoid valve by 3 seconds, while at shutdown it keeps the fan motor running for 6 seconds to ensure proper evacuation of fumes from the boiler.

Operational Features

The DAG02_24 replaces and enhances the functionality of the previous DAG02 model. It is designed to manage token‑activated loads, commonly used for vacuum systems but suitable for any application requiring a timed activation pulse.

When connected to a token acceptor, the unit counts tokens and assigns a configurable operating time (seconds or minutes) to each one. Timing is adjustable via on‑board DIP switches, up to 635 seconds or 127 minutes per token.

Three displays provide real‑time status information, including total working hours (non‑resettable) and total tokens inserted (resettable). An [emergency‑stop input](ca://s?q=Explain_emergency_stop_input_DAG02_24) instantly disables the load and reports the event on the display.

Function input (CHI)

The updated [function input](ca://s?q=Explain_function_input_CHI_DAG02_24) supports two selectable modes via jumper:

• Pause / resume the active token countdown
• Manual load control (enable/disable without tokens)

Power system

The board features an [automatic supply‑voltage detection](ca://s?q=Explain_auto_voltage_detection_DAG02_24) system supporting 90–520 Vac 50/60 Hz without configuration. The same input voltage powers both the electronics and the controlled load.

Auxiliary output

A 12 Vdc / 150 mA auxiliary output is provided. A jumper selects whether it remains always enabled or becomes disabled after an emergency‑stop event.

Protection

The unit includes a [0.5 A fuse](ca://s?q=Explain_fuse_protection_DAG02_24) on the mains input for self‑protection.
