Fixed temperature
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 heating system in the house, the better your heating
economy will be. So make sure not to set your heat curve too high. It is important that the heating
system is carefully balanced so that all parts or the heat emitters (radiators or underfloor) are at the
same temperature.
Thermostatic valves on your radiators or floor 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.

To adjust the engaging and disengaging temperature, press
"Menu" followed by "Select". You are now in line 1.
Use the dial to navigate to display 1.16 and press "Select".
The factory setting is 48°. Please note that this concerns the
engaging temperature to the heat pump. The temperature
from the pump is normally 5-10°C higher. Settings above
48°C are not recommended for technical reasons.
You can also set the difference between engaging and
disengaging the heat pump in display 1.17. The factory
setting is 5ºC. A lower setting results in the heat pump
starting and stopping more frequently. Press "Select" to
adjust.
