Problem Solution
The fan of a slave unit does not start up. 1. When a clip-on temperature sensor is fitted, the parametrised medium
temperature has not been reached.
2. The room temperature has already reached the setpoint.
=> Check parameter setting.
=> Inform Service personnel if the fan is not activated despite the request to do
so.
The fan does not rotate at the set speed. 1. When a clip-on temperature sensor is fitted, the parametrised medium
