Features

• The Aprilaire 4655 manual humidifier humidistat is a manual humidistat that has to be adjusted based on the outside temperature
• This will help prevent water from running down the windows
• This whole house humidistat is designed for low voltage (24 V) control of humidifiers in central heating and air conditioning systems to control humidification equipment
• Cool air near the windows cannot hold the humidity and water will condense on the glass
• In order to prevent this accumulation of condensation, the indoor humidity level is sacrificed by lowering the humidistat
• Wall or duct-mounted
• A template for the plenum cut out is included
• When installing this humidistat for duct-mount, locate at least six upstream of your humidifier, humidifier bypass ductwork or fresh air intake ductwork
• When an increase in relative humidity (RH) expands the nylon ribbon will open the control switch to stop the humidifier's operation
• When a decrease in relative humidity reverses the process, the control switch closes
• Two wire, SPST switch
