This unique controller can be used as both a heating or cooling thermostat and humidistat or dehumidistat at the same time! Temperature and humidity are controlled by separate outlets. No wiring is necessary. Simply plug the device you want to control into the corresponding outlet on the controller, and select the set point you want to maintain.

In Heating mode, in can control electric heaters, heating mats, and cables. In Cooling mode, it can automate fans, coolers, and mist cooling systems.

In Humidify mode, it can be used to turn on a device like a solenoid valve which powers a misting system when the humidity level drops below the level you select. In Dehumidify mode, the controller can turn on a circulation fan, exhaust fan, or dehumidifier when the humidity level rises above the selected level.

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°.

Great for greenhouses

I use this in a greenhouse. Programming is pretty straightforward, just be sure to view the directions for heat and humidity. Seems to accurately alternate between heating and the the wall fan (humidity). Mounts securely to the wall.


Does it all!

This was quite a pleasant surprise. It works beyond my expectations. Does it all. A lot of utility here. I expect to use in it for many projects. I have used it for heating and humidifying concurrently. At the moment its being used for heating and dehumidifying, but it's utility is most notable; it can be setup in various configurations.
