1. Disconnect power from HVAC system. 

2. Install the weather hood, ducting, and damper following 

local practices. Be sure all duct and insulation seams 

are tightly sealed.

3. Mount the transformer and control.

• In general, larger ducting allows higher airflow, minimizes 

additional fan run time and may be needed for larger 

homes.

• Installing a damper directly to the return duct may be 

convenient to support the damper and reduce ducting.

• Fresh air connection should be downstream of sensors 

(such as a humidistat) in return air plenum.

• The EARD6 end stops can be used to reduce the amount 

of airflow in the duct. To prevent complete opening, loosen 

(but do not remove) the wing nut and move the upper lever 

until the desired position is reached. Tighten the wing nut. 

Keep the lower lever in the position shown.

Disconnect power to all systems before beginning 

installation.

1. Wire the control. See wiring diagrams in Fig. 1-10 as 

listed below. All wiring must comply with local codes, 

ordinances, and regulations.

2. Reapply power to system and control.

• Control package allows wire routing through side slots and 

bottom openings.
