Powerful domestic water heating operation
In the case of urgent need of domestic hot water, the domestic hot
water temperature set point can be reached quickly by using the
booster heater. Powerful domestic water heating operation is forcing
the booster heater to operate until the domestic hot water
temperature set point is reached.
This function remains available in solar operation.
Quiet mode operation (
s
Quiet mode operation means that the unit works at reduced capacity
so that the noise produced by the unit drops. This implies that the
indoor heating and cooling capacity will also drop. Beware of this
when a certain level of heating is required indoors.
Two quiet modes are available.

This means that the controller calculates the water
temperature set point based on the outdoor temperature.
In this case, instead of showing the water temperature
set point, the controller shows the "shift value" which
can be set by the user. This shift value is the
temperature difference between the temperature set
point calculated by the controller and the real set point.
E.g. a positive shift value means that the real
temperature set point will be higher than the calculated
set point.
