Single-Pole Thermostat for Baseboard Heaters
The Dayton 3UH07 is a single-pole electric baseboard heater thermostat rated for 120, 208, 240 and 277 volts AC. It carries a contact rating of 22 amps and an 18 amp rating for resistive loads. The white wall-mount housing fits standard installations and includes a mechanical selector dial for temperature adjustment. UL Listed and CSA Certified, it meets safety standards for residential and light commercial heating control.
Replacing Mechanical or Non-Programmable Units
This thermostat replaces older mechanical models that lack multi-voltage support or have worn contacts. The jump is worth it when the existing control cannot handle 22 amps across 120 to 277 volts or when a non-programmable dial is preferred over digital schedules. It does not suit buyers who want programmable setback schedules, Wi-Fi connectivity or multi-stage heating control.
Wall-Mount Integration in Heating Circuits
The unit mounts directly to a wall box and wires in series with the baseboard heater circuit. It requires a compatible 120 to 277 volt supply and a heater load within the 22 amp contact rating. The mechanical dial frees the installer from configuring software or pairing apps. Maximum operating temperature is 80 degrees Fahrenheit. California Proposition 65 warnings apply for chemical exposure.

Questions about this item
What wall-mount dimensions does the 3 in deep, 4 1/2 in high, 3 in wide thermostat need?
The unit fits a standard wall box with 3 in overall depth, 4 1/2 in overall height and 3 in overall width.
How do I wire the single-pole 120/208/240/277V AC thermostat, and what step is often missed?
Connect line and load to the two screw terminals; the common error is forgetting to break the tab for 240/277V operation.
When should the 22 A contact-rated thermostat be replaced?
Replace it if the mechanical dial no longer holds the set temperature or if the contacts exceed the 22 A rating at 120 to 277V AC.
