with window contact function
8.1 Description
The temperature setpoint of the indoor unit can be adjusted via an analog signal from an external
controller. The setpoint is adjusted in +/- 0.5°K increments (see “Table 20: Value table for program
2 temperature setpoint” on page 39).
When the window is opened, the window contact signal at digital input X2a-D1 is interrupted and
switches the running indoor unit o󰀨. What happens next depends on the Auto ON function (see
“8.4 Window contact function Auto ON” on page 40).
The functions of automatic fan speed control and inversion of digital outputs can optionally be
used.
In addition, the digital inputs can be used to switch on the Cooling, Heating, or Fan modes and to
adjust the fan speed. The indoor unit can be switched on or o󰀨 using remote ON/OFF.
The operating or compressor status signals and window contact signal are emitted via the digital
outputs. In the event of a system error, an alarm signal is emitted via a digital output.

Note
●
Only set DIP switches when they are disconnected from the electrical supply. Changed set-
tings only reliably become e󰀨ective after a system restart. An exception here are DIP switches
S2-7 and S2-8, which govern the behavior of the 7-segment display. These DIP switches for
display behavior can also be set during ongoing operation.
●
When reading the current DIP switch positions, bear in mind the horizontal installation posi-
tion of the CompTrol Interface! The ON switch setting is the one closest to the center of the
expansion module.
●
Set inoperative DIP switches to OFF.
