MODEL A76 CONTROL

NOTE: Use 18–22 AWG wire for control wiring.

A Model A76 Control must be wired to the

dehumidifier for external control:

1. Turn off power to the dehumidifier at the

fuse or breaker until wiring is completed.

2. Run a 3-wire thermostat cable (use 18–22

AWG wire) from the Model A76 to the

electrical panel of the dehumidifier.

3. Trim about 1/4" of insulation from the end of

the wires on each end. Insert a small blade

screwdriver into the square opening next to

the desired terminal in the dehumidifier to

open the clamping spring of the terminal.

Insert the wire and remove the screwdriver to

catch the wire. At the Model A76 secure the

wires into the terminals and tighten the cage

screws. See FIGURE 15.

4. Use extra wire to make a small jumper to

wire between the R/+ terminal and one of

the DH terminals of the Model A76 Control.

The Model A76 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 A76 be mounted

at/near canopy height.

Press the ON button on the Model A76 to turn

on the control. The UP/DOWN arrow buttons

are used to set the desired humidity setting. At

all other times, the Model A76 will display the

measured humidity level. Reference the Model

A76 Installation Instructions and Owner's Manual

for set-up.

ALTERNATE EXTERNAL CONTROLS

A Model 8840 thermostat can be used to control

the HVAC equipment, and for dehumidifier

control in place of the Model A76. The

Model 8840 thermostat has Wi-Fi capability.

Additionally, up to four remote sensors can

be mounted near the canopy and connected

to a single thermostat. The four humidity

measurements can be averaged and the

thermostat will turn on the dehumidifier based

on the averaged value.

Reference the 8840 Installation Instructions and

Owner's Manual for set-up and operating details.
