Line-Voltage Thermostats
Regulate line-voltage HVAC systems.
Thermostats for heaters mount to a surface-mount outlet box.
Tamper-Resistant Line-Voltage Thermostats
A built-in guard prevents accidental changes and other tampering and protects these thermostats from damage. These thermostats regulate the temperature in HVAC systems that use direct electrical power. They’re often used with baseboard and wall heaters.
DPST (double pole, single throw) thermostats control two circuits, so they have an “off” setting that cuts power to the thermostat. As a result, they’re more energy efficient and slightly safer than SPST (single pole, single throw) thermostats, which stay at a low setting instead of turning off completely.

Remote-Sensor Hazardous Location Line-Voltage Thermostats
Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space. Use to regulate line-voltage HVAC systems where flammable gases, vapors, and dust are present. Thermostats are rated Class I, Divisions 1 and 2, Group D; and Class II, Divisions 1 and 2, Groups E, F, and G.

Wet-Location Line-Voltage Thermostats
Regulate temperatures in wet locations for HVAC systems that use direct electrical power, such as air conditioners and heaters. These thermostats have a sealed housing to protect against dripping, slashing, and falling liquids.
