Fixed temperature (D series only)

If the heat pump is set at operating mode C with a fixed temperature, then it can only be engaged and
disengaged by the built-in return sensor. There are two displays available for this mode. Please note
that if a mixing valve is connected to the heat pump, the Temp. incr/decre and Temp. fine tune displays
control the settings for the mixing valve opening to the heating system.

Simple tips for saving

The lower you can keep the temperature of the radiators in the house, the better your heating economy
will be. So take make sure not to set your heat curve too high. Operate your heating system as effi-
ciently as possible by making sure that the entire surface of your radiators or your underfloor heating
coils are kept hot.
Thermostatic valves on your radiators or underfloor heating may have a negative effect on your
heating system because they restrict the flow so that the system has to compensate with a higher water
temperature. If thermostat valves are fitted, they should be fully opened, except in bedrooms, where
they can be turned down slightly.
