Keep hot function
The reversible heat pump features a keep hot function that keeps
the heat exchanger hot continuously to prevent sweat from occurring
in the gas boiler switch box.
In case of heating only models, this function can be deactivated
through the parameter settings of the gas boiler.
INFORMATION
Do NOT deactivate the keep hot function if the gas boiler is
connected to a reversible indoor unit. It is recommended to
always deactivate the keep hot function if the gas boiler is
connected to a heating only indoor unit.
Frost protection function
The boiler is equipped with an internal frost protection function that
automatically operates when necessary, even if the boiler is turned
off. If the heat exchanger temperature drops too low, the burner will
switch on until the temperature is sufficiently high again. When frost
protection is active, is displayed on the service display.
