underfloor heating system circuit with mixing valve. A room controller is
recommended, since the heat pump then will automatically adjust flow
temperature.
Only circuits with mixing valve
To ensure that a sufficient amount of energy is available for defrosting, a
buffer cylinder of at least 50L is required for heat pump sizes 5-9 and of
at least 100L for heat pump sizes 13-17.
Fan convector
To ensure that a sufficient amount of energy is available for defrosting, a
buffer cylinder of at least 10L is required.
3.4
Type plate
The data plate is found on the module roof plate.
3.5
Transport and storage
The heat pump module must always be transported and stored upright.
If needed, it may be leaned temporarily.
The heat pump module may not be stored or transported in
temperatures below – 10 °C.
3.6
Heat pump module positioning
• The heat pump module is placed indoors. Pipework between the heat
pump and the heat pump module should be as short as possible. The
pipes must be insulated (
• Leakage drain water from the pressure relief valve should be drained
from the heat pump module to a frost protected outlet.
• The space where the heat pump module is placed must have a floor
drain.
3.7
Checks before installation
▶ Check that all pipe connections are intact and have not shaken loose
during transportation.
▶ Before operation of the heat pump module, the heating system and
the water heater, including the heat pump module, must be filled and
depressurized.
▶ Wiring should be kept as short as possible to protect the system from
downtime, for example during a thunderstorm.
▶ Low voltage wiring must be separated from high voltage wiring by at
least 100 mm.

Connection principle
The principle is based on floating condensation and a immersion heater
in the heat pump module. The user interface manages the heat pump
and the heat pump module according to a set heating curve.
When the heat pump is not able to heat the house on its own, the heat
pump module automatically starts the booster heater and produces
together with the heat pump the desired temperature in the house.
DHW is prioritized and is managed by a sensor TW1 in the hot water
cylinder. While the heater is heated, the heating system heating mode is
temporarily disconnected by a 3-way valve. When the hot water cylinder
is heated, the heat pump heating mode continues.
Heating and DHW mode when heat pump is inactive:
At outside temperatures below app. –20 °C (adjustable value) the heat
pump stops automatically and cannot produce hot water. The booster
heater in the heat pump module will in this case take over both the
heating mode and the DHW production. The heat pump will restart when
the temperature gets above –17 °C.
