INTRODUCTION
The room temperature sensor is designed for temperature measurement of
occupied spaces and utilizes a precision sensor encapsulated in PVC insulated
cable with various thermistors available. The sensor is housed within an
attractive, low prole wall mount enclosure.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning
the temperature sensor. Failure to follow these instructions may result in
product damage. Do not use in an explosive or hazardous environment, with
combustible or ammable gases, as a safety or emergency stop device or in
any other application where failure of the product could result in personal
injury. Do not exceed device ratings.
MOUNTING
The room temperature sensor installs directly to an electrical wall box, or can be mounted directly to the wall. The temperature sensor should
be mounted ve feet from the oor of the area to be controlled. Do not mount the sensor near doors, opening windows, supply air diusers
or other known air disturbances. Avoid areas where the sensor is exposed to vibrations.
Begin by removing the cover. Grasp the bottom of the cover and pull outward from the backplate as shown in Figure 1. Set the cover aside. Do
not remove the PCB from the enclosure base.
Feed at least 6 inches of wire through the wall and out of the junction box. Feed connection wires through the center hole on the backplate
and the PCB, then secure the backplate to the electrical box or wall with suitable screws (not supplied) as shown in Figure 2. The mounting
holes allow for up/down and side to side movement to compensate for unlevel electrical box installation.
Make wire connections as per the "Wiring" section on Page 2.
Re-install decorative cover by placing the top of the cover into the cover holders on the
top of the backplate and snapping the bottom into place.
Two 1/16" Allen Key set screws are provided on the bottom of the enclosure to add
security and lock cover in place. To engage, insert Allen Key and turn counter-clock-wise
2-3 rotations. As seen in Figure 3.

TYPICAL WIRE RESISTANCE VALUES
When using low resistance sensors (i.e. 100  RTD), long wire
runs can add signicant error to the readings. Use the following
chart to determine errors due to wire resistance or consider
using 1000  sensor or a transmitter for better accuracy. Locate
the type of wire being used. Multiply the total length of the wire
(distance from the controller to the sensor and back) by the
number found in the following chart for total resistance.

WIRING
• Follow proper electrostatic discharge (ESD) handling procedures when installing the device or equipment
damage may occur.
• Use 22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit
with wiring used to supply inductive loads such as motors. Connect the cable shield to ground at the
controller only. Make all connections in accordance with national and local codes.
• Connector layout is shown in Figure 5. The diagram shown includes all options, if an option is not ordered,
the connector will not be present.
