AIAS Room controller - installation and operation instruction | 5 / 26
Wiring
All units that share the same transformer and communication loop must use the same transformer-pole for G (terminal 10) and G0
(terminal 11). On the communication loop the A-terminal (terminal 42) should only be connected to another A-terminal and the B-ter-
minal (terminal 43) to another B-terminal. Otherwise, the communication will not work. The communication cable must be a screened
twisted pair cable. The shield must be connected to G0 on one (and only one) Midi controller in each separate power supply loop with
24 V AC. If the length of the loop exceeds 300 m, a repeater is required. The gure below shows the location of the terminals.
Measurement and testing during installation
In order to make measurements and test the inputs/outputs of
a room controller during installation, Regin’s RC-TEST service
adapter may be used. Simply align the pins at the bottom of the
RC-TEST with the terminals contained in the controller’s socket
and then plug the electronics cassette into the terminals at the
top of the device. Testing takes place via a standard multimeter.
