Aprilaire S86WMUPR Installation Manual

Thermostat
1. Wiring
With the dehumidifier unplugged, use 18-24 gauge thermostat wire to connect the Wi-Fi control to
the unit referencing the diagram below. Note that you must leave the jumper wire connected
between the RH/RC terminals on the Wi-Fi control with the RH terminal having two wires running
into it once connected to the unit.
2. Dehumidifier
Plug the dehumidifier in and turn the rocker switch on. While the digital display says OFF, tap the
MODE button to illuminate the screen and then hold the MODE button for three seconds to open
the dehumidifier settings. When REMOTE appears, use the up and down arrows to make sure it is in
the DISABLED position. Hit the mode button three more times to cycle past the VENT and ZONE
options. When EXTERNAL appears on the screen use the up and down arrows to select ENABLED and
hit the MODE button three more times to skip through the screens for DEH W/AC and RH OFFSET.
DONE will blink on the screen. You can then hit the ON/OFF button to turn the unit on to configure
the thermostat.
