Thermostat Cover
. 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 sidewall cooling. 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 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.

Thermostatic Outlets
Thermostatic Outlet Need an inexpensive and simple thermostat? Thermostatic outlets are the answer. These unique devices plug into a standard electrical outlet and have an internal preset thermostat. Outlets come in two models. The Cooling outlet supplies power at 78 and cuts off at 70 and works great for all types of fans including exhaust, circulation, window, attic, and ceiling fans. The Heating outlet supplies power at 35 and cuts off at 45 and is great for automating heaters to keep room temperatures above freezing. Each outlet has two receptacles and can be used with 110/120 volt outlets and appliances (15 amp/110v).
