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 NEMA 7 Class I, Groups C and D; and NEMA 9 Class II, Groups E, F, and G.

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.

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

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

To control heating equipment in washdown environments with splashing water, corrosive liquid, and dust, these switches have a housing that meets NEMA 4X.

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

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 and combustible dust, such as chemical plants, refineries, and grain elevators.

Install directly into drilled and reamed holes.

The faceplate is sealed to meet NEMA 4X for protection in washdown environments with splashing water, corrosive liquid, and dust.

These lightweight controllers have a carrying handle.

These controllers turn on and off in short cycles to continuously maintain a stable set temperature.

Protect temperature-sensitive materials in refrigerators and freezers with one of these thermometers that sound an alarm and flash the display when temperature rises above your activation point.
