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 sloed
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.)

Adjustments and Calibration

More Information

Thermal calibration is not required. Minimum and
maximum control points can be calibrated before or
aer the thermostat has been installed.

1. Turn setscrews CW and remove cover.

2. Verify 16 VDC between the “+” and “–” terminals.

3. Remove setpoint slider stops (HFO-0027) if
necessary.

4. Measure “Tx” to “–” for output voltage. (See the
table on page 2 and the graphs on pages 3 and 4
to determine the correct T terminal.)

5. Maximum limits MUST be greater than
minimum limits. If in doubt, turn maximum limit
fully clockwise (increase) before proceeding.

NOTE: Dials rotate approximately 200° (8:00–4:00).

DO NOT force dial beyond stop.

6. Connect a voltmeter to the meter taps (using an
HSO-5001):

a. The two holes on the right are for the

minimum and maximum.

b. Measure actual ow in le holes. The

thermostat must be wired to a controller for
this option.

7. Always adjust the minimum rst. Adjust setpoint
to request minimum ow using the minimum
dial:

• DA Cooling; Set point > Room Temp.

• RA heating; Set point < Room Temp.

NOTE : Limits may be set at the CSP series

controller or the thermostat. If seing min./

max. limits at the thermostat, the CSP’s
Min. dial must be turned fully CCW to “0”
AND the Max. dial must be turned fully
CW to “100.” This ensures that the CSP will
not aect the limits.

8. Adjust the setpoint to request maximum ow
using the Max. dial:

• RA Heating; Set point > Room Temp.

• DA Cooling; Set point < Room Temp.

9. Reinstall the cover and turn setscrews CCW until
the cover is secure.

For more wiring and calibration details as well as
sample applications, see the CSP-5001/5002 Applica-

tions Guide.
