H4600A DEHUMIDIFIER CONTROLLERS
The H4600A switch makes contact on a relative humidity rise to the set point to start the dehumidifier. A decrease in relative humidity to the setpoint minus the differential breaks the switch contact to stop the dehumidifier.
Turn the control knob clockwise to the setting stop to put the dehumidifier in the ON position. Set to the OFF position by turning the control knob counter clockwise to the stop.

H4600B HUMIDITY CONTROLLERS
The H4600B switch makes contact on a humidity fall to the setpoint minus the differential. In most humidifier systems, the furnace fan must be operating before the humidifier starts. An increase in humidity to the setpoint breaks the switch contacts. (In-room humidifiers, the fan and humidifier operate together.)
Turn control knob clockwise to the stop for ON position. Set to the OFF position by turning the control knob counterclockwise to the stop.
H6600B SPOT CONTROLLERS
The H6600B controllers are used in humidity control systems requiring spdt switching. The switch makes terminals N.C. and C. on a rise in humidity and terminals C. and N.O. on a fall in humidity.
Turning the control knob counterclockwise to the stop will cause the switch (terminals C. and N.C.) to make, turning on the dehumidifier. Turning the switch clockwise to the stop will cause the switch (terminals C. to N.O.) to make, turning on the humidifier.
Place the system in operation and observe through at least one complete cycle to make certain all components are functioning properly.
