Line-Voltage Thermostats
Regulate line-voltage HVAC systems.
Thermostats for heaters mount to a surface-mount outlet box.

Programmable Line-Voltage Thermostats
Set these thermostats to adjust the temperature at certain times each day. They regulate heaters that use direct electrical power, such as baseboard and wall heaters.

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.

Wall-Mount Temperature Switches
(Double Pole, Single Throw)
Switch with Enclosed Housing
Turn heating equipment on or off at a specified temperature. Switches have a probe on a cable for remote temperature readings. Set the actuation point with the adjustment dial.
Switches that control two circuits are double pole, single throw (DPST). They turn two circuits from on to off (normally closed).
Switches with an open housing are often added to existing enclosures or custom installations.
Switches with a pilot light indicate when the switch is on.
Use packing seals and fittings (sold separately) to seal the probe into threaded tanks and pipes.

Washdown Wall-Mount Temperature Switches
To protect these switches from splashing water, corrosive liquid, and dust, the housing meets NEMA 4X for washdown conditions. Switches turn heating equipment on or off at a specified temperature. All have a probe on a cable for remote temperature readings. Set actuation points with the adjustment dial.
DPST (Double pole, single throw) switch turns two circuits from on to off (normally closed).
