WARNING:In the case of configuration as in paragraph 3.2.b (diagram R 1420), connect the thermostat and the valve of the FREEZER plate to terminals TE2 and EV2 respectively and the thermostat and the FRIDGE valve to terminals TE1 and EV1 respectively.For both configurations, the LED signals are identical and described below. AL POWER ON

a)

The LED ON is off on the remote panel. The ‘test LED’ is only made by other LEDs.b) After two seconds, the ‘ON’ LED is switched on with the color corresponding with the value of the Vpower supply.c) The system is ready when the value of the V power supply appears on the display. d) If the voltage is greater than 18V, the parameters relative to 24V power supply are loaded and thepump is powered in PWM at –50%.e) Press ON (1 or 2, depending on the panel type) to activate the EV (1 or 2), pump and compressors withthe consent of the thermostat (1 or 2).f) Press ON again (1 or 2) to switch off the relative EV and, if the other EV is not activated, the pump andcompressors will also switch off.g) At shutdown, a start up lock lasting 300 seconds will be activated.WARNING: If you have a panel with just one ON button, the chip disables terminals EV2 and TE2, so you must modifypoints e) and f) as follows:e) Press ON to activate the EV1, pump and compressors with the consent of Thermostat 1 (TE1) f) Press ON again to switch off EV1, pump and compressors. “ON” LED (Green/Yellow)Green: signals that V power supply > of the V cut-out (VLO) – All OK for start-up Yellow: signals that V power supply > of the V cut-out – The refrigerating unit cannot start During functioning, the alerts are managed in the following way: Changing the power supply V status from VHI to VLO 1V power supply > VHIFixed greenRUN 2VLO < V power supply < VHIFixed greenRUN 3V power supply VHIFlashing yellow for 100 secondsSTOP 8V power supply > VHI for 100secondsFixed greenRUN NB: if it returns to status 2 or 6 from 3 or 7 respectively, the ‘ON’ LED will cease to flash and the 100 secondtimer will be set to zero. “RUN” LED (yellow)LED fixed on after pressing ON with the consent of the thermostat.If the thermostat does not give its consent, but the start up request has been activated (by pressing the ON button), the LED will flash while it waits for the thermostat to close and the pump and compressors to start.
