The controller requires a 240 Volt single phase 3
Amp power supply, which connects directly to the mains input
terminals on the rear of the device.
The two-core network cable should
be screened and have a minimum cross-sectional area of 1.5mm for
networks of up to 1000 meters. This should be increased to 2.5mm
for networks of 1000 to 2000 metres total length. The network
cable terminates at the U1/U3 and U2/U4 connections on the rear
of the device.
Terminals COM-DI, DI1, DI2 and
DI3 are used to remotely operate all of the connected indoor
units.
The indoor units can be enabled
with a contact closure between COM-DI and DI2 this can pulse for
0.5 seconds or a static input. The indoor units can be disabled
by COM-DI the same contact specification applies. If you require
a fire alarm shutdown this ca be achieved by a contact closure
or opening on terminals COM-DI to DI3.
Terminals COM-DO, DO1 and DO2
provide dry contact outputs for connection to other systems. A
relay contact will close between COM-DO and DO2 indicating
system operation and COM-DO and DO1 indicating a fault on any
connected units.
The controller has a standard
RJ45 connector for the connection to the network
Terminals A (+) B (-) are the
connections to the RS485 network to connect to the energy
monitoring relay interfaces and digital input output module.
It is also possible to connect the schedule
timer to CN02 should it be required
