Electronic Room Thermostats
CTE-5100 Series
Mounting
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.

particular application. See the Connections and
Wiring section.
6. Position the trim plate between the backplate and
the thermostat (with the cover removed).

assembly with the two 6-32 x 2" self-tapping
screws (included).
