H46C & E DEHUMIDIFY
CONTROLLERS
The H46C and E switches make contact on a relative
humidity rise to the set point to start the dehumidifier. A
decrease in relative humidity to the set point minus the
differential breaks the switch contact to
humidifier.
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.
H46D & F HUMIDITY
CONTROLLERS
The H46D and F switches make contact on a
humidity fall to the set point minus the differential. In
most humidifier systems, the furnace fan must be
operating before the humidifier starts. An increase in
humidity to the set point breaks the switch contacts.
Turn control knob clockwise
to the stop for
ON position. Set to the OFF position by turning the
control knob counterclockwise
to the stop.
CHECKOUT
Place the system in operation and observe through at
least one complete cycle to make certain that all com-
ponents are functioning properly.
