Component & System Wiring 18
WMVAV Controller Wiring
Notes:
1.)24 VAC Must Be Connected So That
All Ground Wires Remain Common.
4.)When Humidity Sensor Is To Be
Installed A 250 Ohm Resistor Must Be
Installed On The Ground Side Of The
Sensor And Pull Up Resistor PU5
Must Be Removed From The
Controller. See Humidity Sensor
Wiring Diagram In The WMVAV
section of this manual.
5.)If The Slide Adjust Option Is Used On
The Room Sensor , The AUX
Connection Must Be Wired To AIN7.
The Fan Proof Of Flow Switch,
Which Normally Connects To AIN7, Is
Not Available For Use When The
Slide Adjust Option Is Used.
3.)All Communication Wiring To Be 18
Ga. Minimum, 2 Conductor Twisted
Pair With Shield. Belden #82760 Or
Equivalent.
2.)All Wiring To Be In Accordance With
Local And National Electrical Codes
and Specifications.

The VFD Unit Must Be
Configured For 0-10VDC
Input. The Input Resistance
At The VFD Must Not Be
Less Than 1000 Ohms When
Measured At The VFD
Terminals With All Input
Wires Removed.
Warning:
24 VAC Must Be Connected So That All Ground
Wires Remain Common. Failure To Do So Will
Result In Damage To The Controllers.
