Input Function Description
X2a-D1 Remote ON/OFF
The indoor unit or group of indoor units can be switched on and o 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 mode
The signal switches the indoor unit to Cooling mode. The mode can
then no longer be changed using the wired remote control.
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 specied 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.
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.
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.
