H600A HUMIDITY CONTROL
Fig. 2. Mounting the control on the backplate.
Use the wire nuts to make connections to the
leadwires. If one leadwire is not used on the H600A,
insulate it by taping or using solderless connector.
This will prevent shorting.
Connections for Mildew Control
and Dehumidification
Vacation homes that are unoccupied during the hot,
humid summer weather are an invitation to mildew.
The common cure is to simply select a moderate
thermostat setting and let the air conditioner run. By
applying either a low voltage thermostat in
combination with an H600A Humidity Controller or a
W884E Comfort Center, milder can be reliably
prevented and air conditioning energy can be
optimized.

Fig. 3. H600A wiring diagram. Connect red and blue
leadwires to humidifier or red and yellow leadwires
to dehumidifier.
The dehumidistat and thermostat should be wire in
parallel such that by leaving the system switch in
COOL and selecting appropriate set points; for
example, 85 °F (29 °C) and 50% RH, either device will
be able to control the air conditioning equipment. This
independent operation will allow the higher
temperature set point and still prevent mildew by
controlling humidity. For wiring diagram, see
Figs. 4 and 5.
Loads connected to the controller terminals should
not exceed the following electrical ratings:
