IMPORTANT NOTES:
• Do not double trap.
• Prime drain trap when installation is complete.
• Drain line must maintain a constant downward slope.
• Support the drain lines to prevent dips or sags.
• Do not submerge the end of the drain line in water to
avoid microbial growth.
• Vacuum break is recommended when using a condensate
pump or when connecting multiple drain lines.

6A. WIRING AND SET-UP – MODEL A77 CONTROL
The Model A77 will measure the relative humidity and turn the dehumidifier on and off to control the humidity level to the desired setting. The
humidity setting can be adjusted from the control, while the display allows easy access and monitoring of the humidity level in the space. It is
recommended that the Model A77 be mounted at/near canopy height. Shield the Model A77 from direct exposure to HPS or LPS lighting.
NOTE: Use 18-22 AWG wire for control wiring.
Humidity can be controlled using the internal dehumidifier control, a Model A77 control, or a different external control like a thermostat.
Installing an external control eliminates the need to run the dehumidifier blower for sampling, as the control is constantly measuring the humidity
close to the canopy. When the humidity level rises above the setting, the dehumidifier is turned on.
MODEL A77 REMOTE CONTROL WIRING
TO INSTALL AND USE THE MODEL A77 CONTROL,
COMPLETE ALL STEPS:
1. Unplug the dehumidifier or turn off power to the circuit at the
breaker or fuse.
2. Run thermostat cable (use 18-22 AWG wire) from the Model A77 to
the control of the dehumidifier.
3. Trim about 1/4" of insulation from the end of the wires on each
end. Insert the wire into the terminals as shown in the MODEL A77
REMOTE CONTROL WIRING diagram below.
4. Restore dehumidifier power.
TO SET THE DEHUMIDIFIER TO USE THE MODEL A77 CONTROL,
COMPLETE ALL STEPS:
1. With power to the dehumidifier, use the ON/OFF button to set the
dehumidifier to the OFF position.
NOTE: If the display backlight is not on, the first button press (any
button) will only turn the backlight on. Press the button a second
time to achieve the desired function.
2. Hold the MODE button on the on-board control for 3 seconds to
enter the Installer Set-up Menu.
3. The display should now read REMOTE on the left and DISABLED
on the right. Use the UP or DOWN arrow buttons to set this to
ENABLED.
90-1854
4. Once the display reads REMOTE ENABLED, press the MODE button
to cycle through the other settings until the display blinks DONE
for 3 seconds.
5. Use the ON/OFF button to turn the dehumidifier ON. The display
on your unit should read REMOTE.
6. Locate the Model A77 that you just set up. On the Model A77, press
the ON button and use the arrow buttons to set your preferred
%RH setpoint. When setting up in REMOTE mode for the first
time, your dehumidifier will wait 3 minutes before starting to
dehumidify, regardless of ambient conditions.

6B. WIRING AND SET-UP – ALTERNATIVE EXTERNAL CONTROL
Alternatively, use any other humidity control system as long as it has a dry contact, normally open output dedicated to controlling the dehumidifier.
Reference the installation literature provided with the alternative control for wiring, set-up, and operating details.
ALTERNATIVE EXTERNAL CONTROL WIRING
TO INSTALL AND USE AN ALTERNATIVE EXTERNAL CONTROL,
COMPLETE ALL STEPS:
1. Unplug the dehumidifier or turn off power to the circuit at the
breaker or fuse.
2. Run thermostat cable (use 18-22 AWG wire) from the alternative
external control to the control of the dehumidifier.
3. Trim about 1/4" of insulation from the end of the wires on
each end. Insert the wire into the terminals as shown in the
ALTERNATIVE EXTERNAL CONTROL WIRING diagram below.
4. Restore dehumidifier power.
TO SET THE DEHUMIDIFIER TO USE THE ALTERNATIVE CONTROL,
COMPLETE ALL STEPS:
1. With power to the dehumidifier, use the ON/OFF button to set the
dehumidifier to the OFF position.
NOTE: If the display backlight is not on, the first button press (any
button) will only turn the backlight on. Press the button a second
time to achieve the desired function.
2. Hold the MODE button on the on-board control for 3 seconds to
enter the Installer Set-up Menu.
3. Press MODE again and the display should change to EXTERNAL in
the center, and DISABLED on the right. Use the UP or DOWN arrow
buttons to set this to ENABLED.
90-1854
4. Once the display reads EXTERNAL ENABLED, press the MODE
button to cycle through the other settings until the display blinks
DONE for 3 seconds.
5. Use the ON/OFF button to turn the dehumidifier ON. The display
on your unit should read EXTERNAL. Even if there is a demand for
dehumidification according to your external control, the dehumidifier
will wait 3 minutes before turning on for the first time only.
