control function
10.1 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 31: Value table for program
4 temperature setpoint” on page 51).
In addition, the digital inputs can be used to switch on Cooling or Heating modes and to adjust the
fan speed.
The forced Heating and forced Cooling mode functions cannot be adjusted via the wired remote
control.
The functions of automatic fan speed control, forced mode, inversion of digital outputs, and the
louvered ap autoswing function can optionally be used.
The indoor unit can be switched on or o using remote ON/OFF.
The operating, compressor, heating, or defrost signals 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 eective 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.
