Fan and vent motors are commonly controlled with thermostats or controller. While these systems can be operated manually, it is best to have them wired to a thermostat which ensures more even greenhouse climate control and reduces energy costs. One thermostat each is needed for the automated operation of heaters, fans, and shutters. Two-stage thermostats are better for winter climate control. The best thermostats have a +/- 1º-5º differential between the setpoint and turning the systems on or off.
Greenhouse Thermostat Maintenance
Maintaining your greenhouse thermostat or controller box is an essential part of keeping your greenhouse energy efficient. Be sure to follow these tips to make sure your thermostat is at its peak performance all year round!
Ventilation thermostats and sensors should be placed in the center of the planting area, at plant height, and adjacent to the heating thermostat
Thermostats should be enclosed in aspirated boxes for the best accuracy
Thermostats can be checked by taking air temperature with a thermometer near where the thermostat is mounted
+/- 1°F accuracy thermostats are most accurate end energy efficient
Mechanical thermostats have a 4-6°F differential between on and off that keeps the fan running for some time after the setpoint is reached
A controller box can be wired to integrate heating and cooling on one thermostat
Thermostats will perform most accurately when installed near the center of the greenhouse at plant height
