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°.

greenhouse heat thermostat

Had your heat thermostat for over 50 years in my home 10x17 foot greenhouse. I just had to replace it with the same product model. That should speak for itself!
