The multifunction board is equipped with a total of 3 terminals (see Fig. 58), with which the following func-
tions can be realised:
2
1
4
3
5
6
Fig. 58: Terminals
1: On/Off contact CN 46 / 2: KFB-W contact CN 44
3: Rotary switch addressing / 4: DIP switch F1
5: DIP switch F2 / 6: Alarm contact CN 45
ON/OFF1 terminals (CN 46):
Potential-free contact for switching the unit off externally. If this contact is opened (not bypassed), the system
goes into standby. However, with the use of these two contacts switching on is still possible by infrarad
remote control. If this contact is closed (bypassed), the system reverts to the most recently used operating
mode.
Connection of a cable remote control with week
program (KFB-W):
Optionally, the cable remote control with week pro-
gram KFB-W can be connected with the indoor
unit.
The connection also takes place via the multifunc-
tion board supplied to the terminals CN 44 (s.
Fig. 58).
Fig. 59: DIP switch settings
The factory setting is programmed to address 0.
The DIP switch F1 specifies the address range
(e.g. both switches to OFF = address 0-15). The
rotary switch ENC3 has 16 positions with which it
stipulates the respective specific address (e.g. DIP
switch F1 = both OFF and rotary switch ENC2 = 3
gives unit address 2). The customer is not required
to perform any further programming here!
Alarm terminals (CN45):
Potential-free contact for the external transfer of an
alarm. Function in factory setting:
n
If the unit is switched off, the contact is closed
n
If a malfunction is present on the unit, the con-
tact is closed
n
If no malfunction is present on the unit, the
contact is open
CAUTION!
The relay behaviour can be changed via the DIP
switch F2. Switch the DIP switch to ON, in order
to use the NC contact as an NO contact.
