Zones
A building is divided into several zones if the heat demand
differs between different sections of the building.
–
If underfloor heating and radiator heating are installed in
a house.
–
If a house contains more than one independent residen-
tial unit.
If more than one zone is available, the system control con-
trols the available zones.
3.4
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.
3.6
Preventing malfunctions
▶
Ensure that room air can circulate freely around the sys-
tem control, and that the system control is not covered by
furniture, curtains or other objects.
▶
Ensure that all thermostatic radiator valves in the room
where the system control is fitted are fully open.
3.7
Avoiding moisture and mould damage
In heavily insulated rooms that only allow a small exchange
of air, moisture and mould damage may occur.
▶
Ventilate the rooms regularly by opening windows and
activate the
Ventilation boost
function once to save
energy.
