Aprilaire E070 - Wiring; Wiring to a Float Switch; Wiring to Remote Control

WIRING
No additional wiring is needed unless:
• a separate, remote control such as a dehumidistat is to be
used
• a oat switch, either integral to a condensate pump or
mounted to the condensate pan, is used
Use 18-22 AWG wire for any needed wiring� Access the
dehumidier wiring terminals by pulling off the wiring access
cover near the dehumidier control display (see FIGURE 12).
Snap the wiring access cover back into place after completing
all wiring�
WIRING TO A FLOAT SWITCH
Use only if the installation includes a oat switch or a
condensate pump. The dehumidier leaves the factory with a
jumper wire installed in the oat switch terminals. Remove the
jumper and wire the oat switch terminals to the oat switch or
condensate pump overow switch as shown in FIGURE 14�
AIR CYCLING
The dehumidier has an optional ventilation feature that can
be used to circulate air through the dehumidier, to promote
uniform humidity levels throughout the space� When this
feature is enabled, the dehumidier fan can be set to run from
0 minutes (no air cycling) to 60 minutes (continuous) per hour.
NOTE: The on-board control must be used when Air Cycling�
WIRING TO REMOTE CONTROL
The Model 76, when used as a remote control, allows the user
to see the humidity sensed by the dehumidier and adjust
the dehumidier setting from a remote location. This is most
often used when the dehumidier and serves a hard-to-reach
location such as a crawl space or basement�
If using the AprilAire Model 76 as a remote control, wire to the
{+ - A B} terminals. Refer to the installation instructions for the
control being used for wiring details�
NOTE: Air cycling is not an option when using a Model 76 as a
remote control�
