INTRODUCTION
The BACnet Fan Control accessory is a wall-mounted control accessory which allows the user to turn a Renew Aire Energy Recovery Unit (ERV) on and off through the keypad, through a digital input with a remote switch, or through a Building Management System (BMS) with BACnet MSTP
It will control both the supply fan and exhaust fan speeds independently according to settings made through the controller keypad or through the BMS.
MOUNTING INSTRUCTIONS
CAUTION
Whenever electrical wiring is connected, disconnected, or changed, the power supply to the unit and its controls must be disconnected. Lock and tag the disconnect switch or circuit breaker to prevent accidental reconnection of electric power.
A. Remove the captive screw that is holding the base and the front cover
of the unit together.
B. Lift the front cover of the unit to separate it from the base.
C. Pull all wires through the holes in the base.
D. Secure the base to the wall using wall anchors and screws (supplied).
Make the appropriate connections.
E. Mount the control module on the base and secure using the screw
SET-UP AND WIRING INSTRUCTIONS
If the accessory is located close enough to the ERV, it can be powered from the ERV 24VAC power source. For remote connections, wire needs to be 18 gauge.
Either wire in the interlock devices, such as a smoke detector, occupancy
sensor, or jumper from U1 to Common|
