UCM 4.2 Installation and Wiring
• If local codes require enclosed conductors, the zone sensor wires should be installed in conduit.
Do not route zone sensor wires in conduit with 24 VAC or other high power conducting wires.
Multiple UCM’s Per Zone Sensor
Up to three (3) UCM’s may be connected to a single zone sensor and thumbwheel set point.
• Connect terminal connections TB3-1, TB3-2, and TB3-3 in parallel (i.e. daisy chain) from the
master UCM to the slaved UCM(s).
Note: Proper polarity must be maintained.
• Cut jumper wires W1 and W2 on the slaved UCM’s (never cut jumper wires W1 and W2 on the
master UCM).
Multiple UCM’s per Auxiliary Duct Temperature Sensor
Up to three (3) UCMs may be connected to a single auxiliary duct temperature sensor.
• Connect terminal connections TB3-5 and TB3-6 in parallel (i.e. daisy chain) from the master
UCM to the slaved UCM(s).
Note: Proper polarity must be maintained.
• Cut jumper wire W4 on the slaved UCMs (never cut jumper wire W4 on the master UCM).
Zone Sensor Hardwired Option
Depending on the zone sensor options used, a maximum of five wires may be required to run from
the UCM to the zone sensor. The zone sensor options are:
• Zone sensor only (2 wires) - Part Number X13511528010
• Sensor with night set back - Part Number X13511530010
• Zone sensor with external adjustable - Part Number X13511529010
• Zone sensor with external adjustable night set back, timed override (TOV) on/cancel button -
Part Number X13511527010
• Digital zone sensor - Part Number X13511530010
• Communications jack - Part Number X13651467020 (for one box of 12)
Note: All wiring from the zone sensor to the Communication link must be twisted shielded pair
wiring.
Zone Sensor Wireless Option
Wireless Zone Sensor
