Forced circulating water pump operation:
- Make sure that the hydraulic circuit is ready (no leakage, pressure, valves open…)
- Press during 5 seconds the “RESET” button of the CWC2 control board.
The circulating pump starts (if it was stopped). This action has the priority to any control signal from the system.
The circulating pump indicator light “PP” flashes.
- Check that the “W” water flow rate indicator light is on.
EEPROM:
Non volatile memory. Used to store model information (and other data) – see Part 6 parameters.
When replacing A2 board, remove the EEPROM from the old PCB and install it onto the new PCB. If there is trouble with the
EEPROM, replace it with the new one provided with the servicing PCB) and set the necessary parameters with the service
remote controller (for setting procedure, refer to the servicing document or see Part 5).
