NOTES:
• The Model 60 must be continuously powered from “R” and
“C” on the furnace to function properly.
• The minimum VA required is 2.0 VA.
• In order for the humidifier to operate, the HVAC blower must
be running and the Model 60 must be calling for humidity.
WIRING DESCRIPTION:
• Wire external 24 VAC transformer into a constant power source
other than the heating, ventilating, air conditioning equipment
(HVAC) blower circuit. The transformer can be powered off the
120 VAC line at the junction box before it enters the HVAC
equipment. Connect the 24 volt side of the transformer to one
of the “H” terminals on the humidifier control and to one of the
humidifier solenoid valve wires. Connect the other solenoid
valve wire to the other “H” terminal.
• Wire “R” and “C” on the Model 60 to “R” and “C” on the
furnace terminal strip.
• Remove the thermostat “G” wire from the furnace terminal
strip and wire it to “G” on the Model 60 control.
• Wire “Gf” on the Model 60 to “G” on the furnace terminal
strip.
• Wire “W” on the Model 60 to “W” on the furnace terminal
strip.
• Replace cover and knob.
WARNING
120 volts may cause serious injury from electrical
shock. Disconnect electrical power to the furnace
before starting installation.
