Field Wiring Remote Mounted Temperature
Sensor
The low voltage field wiring connections have all been centrally located
within the unit ventilator and are easily accessible.
To simplify field connections, multi-pin plugs are factory provided and
pre-wired with short wire whips (see figure 102). Each of the wires in
these wire whips is capped and should remain capped if not used. The
unit mounted temperature sensor is provided with a quick disconnect
plug (white) with wires numbered 102 and 103, and must be separated
so that the unit mounted sensor is disconnected from the UVC. This
disables the unit mounted sensor (see figure 102). See Figures 103
and 104 for wiring the remote mounted temperature sensor to the unit
control wiring.
All low voltage field wiring connections must be run in shielded cable
with the shield drain wires connected as shown in the field wiring
diagrams.
Installing the Remote Mounted Temperature
Sensor
This describes the installation of the following three wall mounted
sensor models:
• P/N 111048101 – Basic
• P/N 111048103 – Expanded ± 3

Static sensitive components. A static discharge while handling
electronic circuit boards can cause damage to the components.
Discharge any static electrical charge by touching the bare metal
inside the main control panel before performing any service work.
Never unplug any cables, circuit board terminal blocks, relay
modules, or power plugs while power is applied to the panel.
