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

Control one- and two-speed heaters and air conditioners.

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.

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.

Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space.

Regulate temperatures in washdown areas for HVAC systems that use direct electrical power, such as air conditioners and heaters.

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

Control a single heating or cooling device in your enclosure to keep electronics at a safe operating temperature.

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

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

Often used to detect clogged air filters and iced air conditioner coils, these switches sense small changes in pressure between two points in your duct.

When these switches reach a set pressure, they send electronic signals to your programmable logic controller (PLC) to activate automated controls or alarms.

Often used with ovens, dryers, and HVAC systems, these switches detect small differences in air pressure to indicate a filter is clogged or help you maintain a certain air pressure.

To check the difference in pressure between two points, these switches have a dial indicator that shows differential pressure in real time.

With an explosion-proof enclosure that meets NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL and CSA for use where explosive gas or dust may be present. Often used with ovens, dryers, and HVAC systems, they can indicate a filter is clogged or help maintain a certain air pressure.
