<< continuation
▪ [0‑07]: Low outdoor ambient temperature.
10°C~25°C (default: 20°C)
▪ [0‑06]: High outdoor ambient temperature.
25°C~43°C (default: 35°C)
▪ [0‑05]: Desired leaving water temperature
when the outdoor temperature equals or
drops below the low ambient temperature.
Between minimum and maximum leaving
water temperature [9‑07]°C~[9‑08]°C
(default: 12°C).
Note: This value should be higher than [0‑04]
as for low outdoor temperatures less cold
water suffices.
▪ [0‑04]: Desired leaving water temperature
when the outdoor temperature equals or
rises above the high ambient temperature.
Between minimum and maximum leaving
water temperature [9‑07]°C~[9‑08]°C
(default: 8°C).
Note: This value should be lower than [0‑05]
as for high outdoor temperatures colder
water is required.
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.
# Code Description
N/A [8‑0B] 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 EHYHBH05: 13l/min (default)
▪ For EHYHBH/X08: 15l/min (default)
The default values have been set to optimise
comfort and performance. Take care when
changing them.
