Input
Function
Description
X2a-D1
Remote ON/OFF
The indoor unit or group of indoor units can be switched on and off via
the digital input. Forced mode can be activated with DIP switch
S2-5
(see “5.2.2 Remote ON/OFF” on page 26).
X2a-D2
Cooling/Heating
mode
If a signal is applied, the air conditioning unit runs in Cooling mode. If no
signal is applied, the air conditioning unit runs in Heating mode.
X2b-D3
Center/
Center-Remote
When voltage is applied, the CompTrol Interface operates in Center
mode and the wired remote control is disabled. Without voltage, the
CompTrol Interface and the wired remote control operate in Center-Re
-
mote mode (see “5.2.4 Center/Center-Remote” on page 26).
X2b-D4
Analog input
evaluation
Analog input
X3-S
is only evaluated if a signal is applied to
X2b-D4
(see
“5.2.1 Evaluating the analog input” on page 25). If no signal is
applied, a setpoint can be specified via the wired remote control.
X2c-D5
Fan speed
F1
(low)
The signal switches the indoor unit to fan speed
F1
. The fan speed can
then no longer be changed using the
wired remote control
. If auto-
matic fan speed control is activated, digital input
D5
is no longer evalu-
ated (see “5.3.1 Automatic fan speed control” on page 26).
X2c-D6
Fan speed
F2
(medium)
The signal switches the indoor unit to fan speed
F2
. The fan speed can
then no longer be changed using the
wired remote control
. If auto-
matic fan speed control is activated, digital input
D6
is no longer evalu-
ated (see “5.3.1 Automatic fan speed control” on page 26).
X2c-D5
and
X2c-D6
Fan speed
F3
(high)
If fan speed
F1
and fan speed
F2
signals are both applied simultane-
ously, the indoor unit switches to fan speed
F3
. The fan speed can then
no longer be changed using the
wired remote control
. If automatic fan
speed control is activated, digital inputs
D5
and
D6
are no longer evalu-
ated (see “5.3.1 Automatic fan speed control” on page 26).
