Fig. 6. Typical series wiring hookup of H46C with T87F/Q539A combination for dehumidification
and mildew control.
SETTINGS AND ADJUSTMENT
The H46 makes contact on a relative humidity rise to the
set point to start the dehumidifier. On a decrease in
relative humidity to the set point (minus the differential),
the switch breaks contact to stop the dehumidifier. Turn
the knob clockwise to the setting stop to place the H46 in
the ON position. Turn the knob counterclockwise to the
stop to place the H46 in the Off position.
CHECKOUT
After all mounting and wiring is completed, turn on the
power supply. Place the system into operation by turning
the setting knob toward the low end of the scale until the
dehumidifier motor starts. Turn the setting knob slowly
toward the high end of the scale until the dehumidifier
motor stops.
