Main Operational Features Pump motor output driven internally by 3 separate relays Electronics fully encapsulated in epoxy resin for dust and moisture protection	TLR 20 — Technical Details 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)	TLR-EC — Technical Details 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 — the end user can reset the maintenance counter via the reset button. Unlimited operation — the machine continues operating while signaling maintenance; reset is possible only via software. Dual‑threshold lock — 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 signaling LED 1 + LED 2 steady ON — full lock due to missing maintenance LED 1 blinking 1 s / 1 s — machine inactive 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	TLR FULL — Technical Details 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.
