STEP 10: Model 60 Wiring for Model 400, 500, 600 and 700 Series Humidifiers – See Figure K
WARNING
120 volts may cause serious injury from electrical shock. Disconnect electrical power to the furnace before starting installation.
Strip the wires used for all HumidifierControl terminal connections 1/4 inch.
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 external24 VAC transformerinto a constantpower source other than the heating,ventilating,air conditioning equipment (HVAC) blower circuit. The transformercan be poweredoff the 120 VAC line at the junctionbox before it enters the HVAC equipment. Connectthe 24 volt side of the transformer to one of the “H” terminalson the humidifiercontrol and to one of the humidifier solenoid valve wires. Connectthe 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.
