Enclosure heater
Filter fan, cooling equipment, signal device
The MFR 012 electromechanical thermostat is designed to control the relative humidity inside
enclosures. When connected to an enclosure heater (dehumidifier), it will energize the heater
at the humidity set point in order to raise the dew point. This helps prevent damage and mal-
function of electronic components caused by condensation and corrosion.
The MFR 012 can also be used to control cooling fans, warning lights or other devices.
