INTRODUCTION
The RS332NE Non-Programmable Setback Thermostat with
Economizer Controls represents advanced solid-state,
microcomputer temperature controls. The thermostat incorporates
state-of-the-art technology packaged in an extremely low profile
designer series case. They are a direct replacement for 300
series and DSL series non-programmable units. The Ultra-Touch
push-buttons and easy-to-read, blue backlit LCD display provide
the ultimate in user friendly operation of the heating and air
conditioning, including gas, electric, oil and heat pump systems.

BUTTON OPERATION
THERMOSTAT LOCATION
To ensure proper operation, the thermostat should be mounted
on an inside wall in a frequently occupied area of the space. In
addition, its position must be at least 18” (46 cm) from any
outside wall, and approximately 5’, (1.5 m) above the floor in a
location with freely circulating air of an average temperature.
Be sure to avoid the following locations:
•
Behind doors or in corners where freely circulating air is
unavailable
•
Where direct sunlight or radiant heat from appliances might
affect control operation
•
On an outside wall
•
Adjacent to, or in line with, conditioned air discharge grilles,
stairwells or outside doors
•
Where its operation may be affected by steam or water pipes
or warm air stacks in an adjacent partition, or by any
unheated / uncooled area behind the thermostat
•
Where its operation may be affected by lighting dimmers next
to it
•
Where its operation will be affected by the supply air of an
adjacent unit
•
Near sources of electrical interference such as arcing relay
contact
REMOVING THE THERMOSTAT FROM THE
BACKPLATE
1. Insert a flat blade screwdriver or coin 1/8” into the slot located
in the bottom center of the thermostat case and twist 1/4 turn.
When you feel or hear a click, grasp the case from the bottom
two corners and separate from the backplate as shown in the
diagram at the left. Some models require more force than
others when separating due to the number of terminals used.
2. Swing the thermostat out from the bottom.
3. Lift the thermostat up and off the backplate.
4. Place the rectangular opening in the backplate over the
equipment control wires protruding from the wall and, using
the backplate as a template, mark the location of the two
mounting holes
NOTE:
There are several versions of the RS300N thermostat.
The wiring instructions for the equipment are identical.
5. Use the supplied anchors and screws for mounting on drywall
or plaster; drill two 3/16” (5mm) diameter holes at the marked
locations; use a hammer to tap the nylon anchors in flush to
the wall surface and fasten backplate using the supplied
screws. (Do not over tighten!)
6. Connect the wires from your system to the thermostat
terminals as shown in the wiring diagrams. Carefully dress the
wires so that any excess is pushed back into the wall cavity or
junction box. Ensure that the wires are flush to the plastic
backplate. The access hole should be sealed or stuffed to
prevent drafts from affecting the thermostat.
NOTE:
This product must be supplied from a UL/CSA
LISTED Class 2 power supply. Operation from other supplies
may result in a potential fire risk.
