CTE-5100 Series Thermostats:
The CTE-5100 series thermostats are designed to be used with the CSP-5002 controller actuator. CTE-5100’s are provided with limited and
unlimited outputs. The limited output(s) is (are) used to provided minimum and maximum limits to a CSP-5002. The unlimited output(s) is
(are) used to operate fan and heat sequences.
Models are available for cooling, cooling with reheat, cooling / heating changeover and day/night or set-back applications. Temperature
averaging and/or overrides may be accomplished. Consult Nailor control submittal for applicable thermostat model.

Thermostat Specifications.
Installation:
Thermostats must be mounted horizontally,(or vertically by using an optional vertical scale plate), utilizing the HMO-5030/5031 backplates
for mounting to a standard 2" x 4" electrical box, or the optional HMO-5023 drywall bracket for mounting to hollow walls. Thermostats should
be mounted on a wall in an area not affected by sunlight or drafts, to sense the average room temperature.
Electrical box mounting:
Install the HMO-5030/5031 backplate to the electrical box using the two 6-32 screws, supplied with backplate – do not tighten. The backplate
is provided with one slotted mounting hole for leveling. Level the backplate and tighten the two mounting screws. Pull thermostat wires
through backplate and decorative trim plate. Connect thermostat wires to the thermostat according to the wiring diagram supplied with the
unit. Position the trim between the back plate and the thermostat, secure the assembly with the two 6-32 x 2" self tapping screws supplied.
Hollow wall mounting:
Loosely mount the HMO-5023 bracket to the thermostat using the two 6-32 x 2" screws. Pull all thermostat wiring through the opening on
the bracket. Connect thermostat wires to the thermostat according to the wiring diagram supplied with the unit. Center and align the
thermostat while tightening the mounting screws.
