Plug in the thermostat, then plug your heater into the socket on the thermostat's plug.

Commonly used with hydronic heaters, this thermostat senses the temperature of liquids. The thermowell protects the sensor.

Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space. Thermostats work with line-voltage HVAC systems.

Use to regulate line-voltage HVAC systems where flammable gases, vapors, and dust are present. Thermostats are rated Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

Also known as snap discs, these thermostats switch on cooling systems or switch off heating systems when equipment gets too hot.

Keep electronics in your enclosure from getting too hot or cold with these thermostats that control two devices at once.

If ambient air temperature rises above or falls below an actuation point, this thermostat flashes the current temperature reading on the display and shows a “high” or “low” message.

These thermostats work with low-voltage HVAC systems that have only one speed.

As the temperature goes up, the pressure in the system goes up.

Since these switches don’t have a housing above the probe, they are often used in tight spaces and low-clearance areas.

Install the threaded probe directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature.

Switch heating equipment on and off at a specified temperature by installing these electronic switches directly into tanks, pipelines, and other process components. Simply twist the outer rings to adjust your set point—no need for tools.

These temperature switches mount on walls and take remote temperature readings with a probe on a cable.

Housing is UL listed for environments with flammable gases, combustible dust, and ignitable fibers, such as chemical plants, refineries, and grain elevators.

Install these controllers in DIN panel cutouts to maintain your heating equipment’s temperature. When your machine gets too hot, they turn it on and off in short cycles to cool it down.

To protect equipment and personnel, these controllers shut down your machine when it gets too hot and won’t let it turn back on until they’re reset. Mount them to DIN panel cutouts in your heating equipment.

For protection in washdown conditions with splashing water, corrosive liquid, and dust, these controllers have a housing that meets NEMA 4X.

Open or close a circuit when a fusible link melts. These switches are often used as a safety switch to shut off hydraulic equipment.
