1
F1: Extended address allocation
Addresses 00-15 can be allocated using rotary switch ENC1 if both F1 DIP switches are set to “OFF”. Move
DIP switches 1 and 2 to different positions to allocate up to 64 addresses.
2
F2: Function logic of the On/Off contact
If both F2 DIP switches are set to “OFF”, the system starts up when the CN46 contact is closed. If the CN46
contact is opened the system switches to standby. If the CN46 contact is closed again, the system operates
in the most recently used operating mode.
3
CN46: Potential-free contact for external on/off switching
Bridged in the factory. If the contact is closed, the system is in normal operation. If the contact is opened the
system switches to standby mode. Closing the contact again switches the system to the most recently used
operating mode.

ENC3: Addressing of the indoor unit
An address can be assigned to the indoor unit using the rotary switch. The address is set to “00” in the fac-
tory. If you use several units with a Smart Control Touch Controller, they must be set to different addresses.
The letters A-F stand for addresses 10-16.

CN41/CN42: X, Y, E interface for superordinate controller
A superordinate controller (such as a mart-Control Touch SC-1) can be connected using the X, Y and E inter-
face. Observe the installation and operating instructions of the respective accessory part when doing this.

CN45: Potential-free alarm contact
In the event of a system malfunction, this contact is closed. Customer-provided unit control technology (GLT)
can be connected here to provide fault notification.
