Important
If the return water temperature is below 10 °C, screed drying will
start using the electrical back-up until the return water reaches a
temperature of 20 °C (to prevent it taking too long, particularly in
winter).

Drying screed without the heat pump outdoor unit
The indoor module can be used for drying screed using the electrical
back-up. It is not necessary to connect the outdoor unit.
1. Switch on the indoor module and activate the screed drying function.
2. Adjust the parameters for screed drying.
If the outdoor unit is not connected, the back-ups will start
automatically.
