FAN COIL ROOM THERMOSTAT
CH130ARR2
CONNECTING SEVERAL MODULES TO ONE THERMOSTAT
A CH133AR2 - CH133RR - CH130AR2 - CH130ARR - CH130RR thermostat can control up to five fan-coils simultaneously,
using only two wires to connect to the various actuation modules. In this case, only one of the two CH176D modules
must have the “BUS selector” in “MASTER” position, while all others must be left in “SLAVE” mode (default setting). The
temperature probe connected to the actuation module set up as “MASTER” is the one read by the thermostat.
The connection between the various devices must be made as per the diagram in the following figure.
