FAN CONTROL:

The fan has 2 speed settings which can be adjusted in the menu "FanOper". Normally, the highest speed should be used.
If the heat pump in some cases would interfere, the low speed setting can be selected without having a significant
influence on the heat pump efficiency.
With air duct connections the high speed setting must be used. The fan can in the "FanCon" setting be connected so that
constant ventilation can be made. The fan will in the setup 0 be disconnected with heat pump. In setup "Low" it runs on
low speed and in setup "High" it runs high speed with heat pump disconnected.
