11.2.2 Control method OUT
The supply temperature is controlled the same as above but there is no
adjustment for indoor temperature.
11.2.3 Control method IN
The supply temperature is controlled by the house's average indoor temperature.
The method is best suited when only radiator heat is used.
There is a risk of temperature fluctuations due to slowness in heating systems if
underfloor heating is used.
The indoor temperature sensor is located in the heat pump's exhaust air intake but
alternatively may an external indoor sensor be used.
The thermostats in all larger rooms should always be left completely open, i.e. in
max position or completely removed.
Bedrooms can be regulated with thermostats.
