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

Regulate line-voltage HVAC systems.

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

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.

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.

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

Connect to a Wi-Fi network so you can remotely program, monitor, and control the temperature from a computer, tablet, or smart phone.

Restrict access and protect thermostats from damage.

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

Actuators automatically switch between incremental and proportional control to adjust dampers to regulate airflow.

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.

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.

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

Often used to control heat cable output, these switches have mounting holes for surface installation.

For high accuracy in applications with fluctuating conditions, these controllers have proportional-integral-derivative (PID) software with fuzzy logic that learns system behavior and automatically compensates for changes.

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

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.
