Description
This is a BRAND NEW OEM Aprilaire Humidifier Humidistat (Manual Humidifier Control). The Aprilaire 4655 Humidistat is designed for low voltage service to control humidification equipment. An increase in relative humidity expands the nylon ribbon which opens the control switch to stop operation of the humidifier. A decrease in relative humidity reverses the process and closes the control switch. Can be wall mounted or mounted on return plenum. For duct mount, locate at least 6" upstream of humidifier, humidifier bypass ductwork or fresh air intake ductwork. Thanks for looking and good luck!
Function:
Humidifiers increase the humidity in room or building. A humidifier that is attached to your HVAC system will increase the humidity coming out of the home's air duct registers.
