sensor not connected or damaged
Flow sensor not connected or damaged
- Check the wiring connection of the modbus cable.
- Red led on TDM not blinking-> change TDM control board
Check water leakage of the hydraulic circuit
- Water pressure switch damaged
- Wiring of water pressure switch damaged
- Check wiring connection between TDM end Energy Manager
- Check water fl ow of the heating circuit
- DHW tank sensor not connected or damaged
- Check 3-way valve (DIV1) blocked in DHW position
- Check water circulation of the underfl oor zone
- Check main circulation activation
- Check water fl ow sensor detection by par. 17.11.3
Check anode connection
- Check water presence in the tank
- Check anode status
- Hydraulic scheme not selected by parameter 17.2.0
Function not selected by parameter 17.1.0
Function not selected by parameter 17.1.1
- Check water fl ow of the cooling circuit
Check if main circulation is active before the heat request
- Check the water fl ow detection by water fl ow sensor (see par. 17.11.3)
before the heat request
Check the compressor's frequency after the end of the heating demand via
parameter 17.12.1
Check the fl ow temperature sensor and return temperature sensor place-
ment.
