NOTICE
If you enable the efficiency calculation, make sure that the installed auxiliary boiler
capacity is large enough to cover the building's space heating demand. Enabling the
function for a too small boiler may lead to undesirable and potentially damaging on/
off switching behavior of the heat pump!
Continuous heating
The continuous heating function allows to provide space heating also during unit
defrost and can thereby increase space heating comfort. The space heating
temperatures provided during defrost depend on actual storage tank
temperatures.

Equilibrium: Deactivate backup heater (and
tank heating support in case of a bivalent system)
above the equilibrium temperature for space
heating?
▪ 0: No
▪ 1: Yes
Equilibrium temperature: Outdoor
temperature below which operation of the
backup heater (and tank heating support in case
of a bivalent system) is allowed.
Range: –15°C~35°C
Description
▪ 0 Yes: When solar energy is provided and
storage tank temperature is above limit
temperature, heat pump and boiler are
switched off.
▪ 1 No: Heat pump and boiler can operate also
while solar energy is provided.
