INFORMATION
In order to optimise comfort as well as running costs, it is
recommended to choose weather-dependent setpoint
operation. Set the settings carefully; they have significant
influence on heat pump as well as boiler operation. Too
high leaving water temperature can result in constant boiler
operation.
Leaving water temperature: Additional zone
Only applicable if 2 leaving water temperature zones are present.

Pump control: Flow target
The hybrid module is designed to operate with a fixed flow. This
means that the pump is controlled to work at a flow target set by the
installer. The installer can set the flow target for:
▪ heat pump only operation,
▪ hybrid operation,
▪ gas boiler only operation.

▪ [0‑03]: Low outdoor
temperature. –40°C~+5°C (default: –
10°C).
▪ [0‑02]: High outdoor
temperature. 10°C~25°C

▪ [0‑01]: Desired leaving
temperature when the
temperature equals or drops below
the low ambient temperature.
[9‑05]°C~[9‑06]°C (default: 60°C).
Note: This value should be higher
than [0-00] as for low outdoor
temperatures warmer water
required.
▪ [0‑00]: Desired leaving
temperature when the
temperature equals or rises above
the high ambient temperature.
[9‑05]°C~min(45, [9‑06])°C (default:
35°C).
Note: This value should be lower
than [0-01] as for high outdoor
temperatures less warm water is
required.
Description
Target flow rate during heat pump
operation.
The default value is set to deliver the
nominal capacity of the heat pump with
a ΔT over the emitter of 5°C. Decrease
this value if the room temperature is
constantly higher than the desired room
temperature. Increase this value if you
feel discomfort in heat pump only
operation.
Range: 10~20 l/min
▪ For CHYHBH05: 13 l/min (default)
▪ For CHYHBH08: 15 l/min (default)
The default values have been set to
optimise comfort and performance.
Take care when changing them.
