To avoid damage due to moisture in very warm or humid climatic zones resulting from
lack of air circulation in energy saving mode, the fan will not be switched off when se-
lecting the function “Temperature-independent fan control“ (with DIP switch no.1)
A changeover switch can be connected to status input D1-GND. When the switch
closes its contact (caused by an open window, for instance), the operating mode will
change from normal operation to energy saving mode (provided DIP switch no.2 is set
to ON), or from normal operation to standby (provided DIP switch no.2 is set to OFF). If
the room temperature falls below 8 °C and if DIP switch no.3 is set to OFF, frost protec-
tion mode will become active.
The operating action of the switch (N.C. or N.O.) can be selected.

Without input for return air temperature sensor,
without frost protection function
Mechanical design
The unit consists of two parts:
•
A plastic housing which accommodates the electronics, the operating elements and
the built-in room temperature sensor
•
A mounting base
The housing engages in the mounting base and snaps on.
The base carries the screw terminals. The DIP switches are located at the rear of the
housing.
