Electronic Room Thermostats
CTE-5100 Series
Installation Guide
General
CTE-5100 series thermostats require a scale plate
assembly and a cover, which must be ordered
separately. To ensure accurate temperature sensing,
mount thermostats on interior walls and away from
heat sources, sunlight, windows, air vents, and air
circulation obstructions (e.g., curtains and furniture).
These thermostats may be mounted horizontally or
vertically to a standard 2 x 4" (51 x 102 mm) handy
box using a HMO-5024/5026/5030/5031 backplate or
directly to a hollow wall using an HMO-5023 kit.
Electrical Box Mounting
1. Install, but DO NOT TIGHTEN, the HMO-
5024/5026/5030/5031 backplate to a handy box
using the two 6-32 screws (included).
2. Adjust and level the backplate using the sloed
mounting hole.
3. Tighten the two mounting screws.
4. Pull all thermostat wires and cable through the
backplate and decorative trim plate opening (of
the HMO-5024/5026/5030/5031). Be careful not to
damage the trim plate while wiring.
5. Connect the thermostat’s wires according to its
particular application. See the Connections and
Wiring section.
6. Position the trim plate between the backplate and
the thermostat (with the cover removed).
7. Align the mounting holes and secure the
assembly with the two 6-32 x 2" self-tapping
screws (included).
Hollow Wall Mounting
Thermostats may be mounted on a hollow wall up to
5/8" thick using the HMO-5023 hollow wall mounting kit.
1. Using the template, cut a 1-1/2 x 2-11/16" opening
in the drywall.
2. Loosely mount the HMO-5023 bracket to the
thermostat (with cover removed) using the two
6-32 x 2" screws.
3. Pull all thermostat wires or cable through the
bracket’s wiring/cable access hole(s).
4. Connect the thermostat wires according to its
particular application. See the Connections and
Wiring section.
5. Insert bracket diagonally, through the wall
opening, and then center and tighten the screws.

Setpoint Stops
Optional setpoint stops can be used to lock or limit
the setpoint range. Each HFO-0027 setpoint stop
strip (accessory sold separately) contains four stops.
1. Break a stop from the strip by gently folding on
the seam with pliers.
2. Insert a stop into the slider track on one or both
sides of the slider.
3. Repeat for second slider.

Scale Plate
1. Install scale plate under the setpoint indicators.
2. Align mounting holes.
3. Insert the two (supplied) HPO-0046 retaining pins
into the holes.
4. Twist pins 1/4 turn to rmly seat.

Cover
NOTE: When using a blank cover (without a
window), remove the nger pads on the
setpoint sliders. Hold the slider in place,
insert a small at blade screwdriver into
the slot in the metal slider. Twist the
screwdriver slightly to pop the pad o.
With the window style covers, a symbol-coded label
strip is included to apply to the covers for setpoint
indication.
1. Remove the window from the cover by applying
light pressure on its underside and exing
upward.
2. Peel o correct identity label from the strip of
labels provided.
3. Position the label on the cover’s recessed area.
4. Snap window back in place.
5. Slide cover onto base.
6. Locate the setscrew on each of the thermostats
short sides.
7. Using a 1/16" hex wrench, turn setscrews outward
CCW until the cover is secure. (Turn setscrews
CW to remove cover.)
