6.1 - INTERNAL UNIT ADDITIONAL ELECTRIC HEATERS MANAGEMENT
The internal unit is equipped with two electric heaters. The electric heaters are enabled to integrate power
in heating mode, domestic water production mode, during the execution of the Anti-Legionella cycles or for
start-up of the system in case of low temperatures or in building sites for screed drying.
Parameter "ADDR217"
0 = not enabled
1 = one heater enabled for backup
2 = two heaters enabled for backup
3 = one heater enabled for low-temperature start
4 = two heaters enabled for low-temperature start
6.1.1 - Backup
The first electric heater EH1 activates if:
- The heat pump has been in heating mode or domestic hot water production mode for at least ADDR235
minutes.
- The external ambient temperature is lower than ADDR227 degrees Centigrade.
- The delta on water is at least 4°K with respect to the setpoint.
After further 15 minutes from the activation of the first electric heater, if these conditions persist, the second
electric heater activates.
The backup function with electric heaters is not active if the external heat source ADDR226 is enabled (ON).
