Operating limit
Misc.:
The accelerator pump can be stopped using parameter P121:
P121 = NO: accelerator pump turned off if boiler operating.
Moreover, a LOW INT WATER FLOW fault must not prevent the boiler from operating. Therefore, the boiler is authorised to
start up even if this fault appears.
P121 = YES (default value): accelerator pump continuous operation.
5.5.2.2 Boiler controlled by its own HomeConnect controller P11 = BOILER and P12 = SIMULTANEOUS
Typical application : boiler with basic control.
When P11 = BOILER and P12 = SIMULTANEOUS, the burner and the heat pump are controlled by the HomeConnect controller
using the water law entered on the terminal (parameters P152 to P156).
In simultaneous operation, the HomeConnect controller also provides a contact to control the boiler's 3-way distribution valve.
This contact (terminal block J33 - terminals 1 and 2) is permanently closed once the controller authorises boiler operation. The
contact opens 5 minutes after the boiler operation prohibiting order in order to recover as much heat as possible from the hot water
contained in the boiler's heating source.
Operating limit
If only the boiler is authorised to operate, the control terminal manages the ambient temperature and the controller controls the
boiler operation based on the ambient air setpoint (P150 or P151). Control is then via the P183 differential (factory setting = 1°C).
Example:
Heating mode in comfort mode: P150=21°C and P183=1°C.
The boiler is authorised to operate if the ambient temperature is below 20°C and is turned off once the ambient air setpoint of
21°C is reached.
