732 Buffer low probe error
902 System flow sensor damaged
923 Heating circuit pressure error
924 HP communication error
927 AUX inputs correspondence error
928 Energy supply shutdown configura-
tion error
933 Flow sensor overtemperature
934 DHW tank sensor damaged
935 Tank overtemperature
936 Floor thermostat 1 error
937 No circulation error
938 Anode fault
940 Hydraulic scheme not defined
Temperature control activation based on the external sensor
External sensor not connected or damaged. Check the sensor's connection
and replace it, if necessary.
Buffer filling inhibited. Check the hydraulic diagram.
Buffer sensor not connected or damaged. Check the sensor's connection
and replace it, if necessary.
Buffer filling inhibited. Check the hydraulic diagram.
Buffer sensor not connected or damaged. Check the sensor's connection
and replace it, if necessary.
Buffer filling inhibited. Check the hydraulic diagram.
Buffer sensor not connected or damaged. Check the sensor's connection
and replace it, if necessary.
Delivery sensor not connected or defective. Check the sensor's connection
and replace it, if necessary.
Check for any water leakages in the hydraulic circuit
Faulty pressure switch
Defective cabling of the pressure switch. Check the connection of the pres-
sure switch and replace it, if necessary.
Check the cabling between the TDM board and the Energy Manager
Verify the configuration of parameters 1.1.3 and 1.1.4
Check the configuration of parameter 1.1.5
Check the flow in the primary circuit. Delivery sensor not connected or
defective. Check the sensor's connection and replace it, if necessary.
Calorifier sensor not connected or defective. Check the sensor's connection
and replace it, if necessary.
Check whether the 3-way valve is locked in the DHW position. Check the
connection of the calorifier's sensor and replace it, if necessary.
Check the flow of the under-floor system. Check the connection of the
thermostat on the IN-AUX2 STE terminal of the Energy Manager and/or
STT of the TDM. If the thermostat of the under-floor system is not present,
apply an electrical jumper to terminal IN-AUX2 STE of the Energy Manager
and/or STT of the TDM.
Check that the main circuit has activated
Check the connection of the anode
Check whether there is any water in the indirect cylinder
Check the condition of the anode
Check the configuration of parameter 1.2.6
Hydraulic diagram not selected through parameter 1.1.0
