1.2 Equipment overview

1.2.1 With closed control flap and standard 
display

1.1 Equipment description

The FEK control module only works in 
conjunction with the weather-compensated 
WPMi control unit. It enables the convenient 
entry and display of system parameters, e.g. 
outside temperature, relative humidity and 
heating circuit parameters (e.g. heating times 
and required room temperature) for the 
heating system from the user’s living room. 
This allows the constant monitoring and 
optimising of the heating system, both in 
heating and in cooling mode.
In addition, hooking up a room temperature 
enables the correction of the weather-
compensated WPMi control unit.

1.3 Important information

The control module must only be 
installed and maintained by qualified 
contractors.

1.4 Operation

The operation is split over three control levels. 
Control levels 

1 and 2

 are accessible to users 

and contractors alike. Control level 

3

 is only 

designed for qualified contractors:

Control level 1

 (control flap closed)

This enables the adjustment of operating 
modes, such as standby mode, programmed 
operation, constant day or setback mode (for 
this, see section 1.5.1).

Control level 2

 (control flap open)

This enables parameters, such as room 
temperature, heating programs, etc. to be 
adjusted (for this, see section 1.5.5).
