Hybrid manager
If a heat pump and an additional boiler are connected, you
can use the hybrid manager. If there is a heat demand, the
hybrid manager picks the heat generator that is more cost-
efficient. The hybrid manager decides which heat generator
to operate based on the tariffs that are set in relation to the
heat demand.
To ensure that the heat pump and the boiler can work effect-
ively and in synch with one another, the tariffs (
must be set correctly. If the tariffs are set incorrectly, this res-
ults in increased costs.
3.5
Frost protection function
The frost protection function protects the heating installa-
tion and flat from frost damage. The frost protection function
monitors the outdoor temperature.
If the outdoor temperature
–
falls below 4 °C, the system control switches the heat
generator on after a frost protection delay time, and
brings the target room temperature to 5 °C.
–
rises above 5 °C, the system control does not switch the
heat generator on but monitors the outdoor temperature.
Note
The competent person can set the frost protection
delay time.

Preventing malfunctions

Ensure that room air can circulate freely around the sys-
