This single stage thermostat comes prewired with an 6' grounded Plug-in power cord. Simply plug the thermostat into a standard 110/120 volt outlet. Then plug any 110/120 volt appliance into the outlet on the plug of the thermostat. Select heating thermostat to control a heater or cooling thermostat to control fans and/or louvers.
*Plug-in thermostats can not be used with our gas heaters. They require 24 volt thermostats.


  • Wide temperature range: 30° to 110° F
  • Fixed 3 degree differential
  • Plug-N-Play, no wiring needed (15 amp/120v max)
  • Includes 6' plug-in cord
  • Waterproof NEMA 4X enclosure

Thermostat placement in a greenhouse: To get the desired temperature, thermostats should be located at plant height near the center of the greenhouse where they are not influenced by drafts or the temperature of an exterior wall. It is best if both heating and cooling thermostats are located together and protected from direct contact with sunlight and water. One simple way to accomplish this would be to mount the thermostat(s) to a piece of wood (or other nonconductive material) with a top on it like in the picture to the left. Wood should be painted white to shade it from the sun.

What is a Differential? The difference between on and off setpoints on a control. For temperature, it is the difference in degrees between the thermostat's on and off setting. If you set a heating thermostat with a 3 degree differential to 71°, it will supply power at any temperature below 71° and cut off at 74° (3 degrees above the setpoint). A cooling thermostat would cut on above 71° and off at 68°.

Solid Construction and Works Awesome

This unit works great controlling a fan in my greenhouse to add some extra ventilation during the hot days. Highly recommend it!


Nice temperature controller!

I purchased the corded one, which made it very simple to install! Just plug it in, and then plug in the shutter controller motor! Opens the shutters when the temperature reaches the set point.
