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).
