Warning:
24 VAC Must Be Connected So That All Ground
Wires Remain Common. Failure To Do So Will
Result In Damage To The Controllers.

Power Consumption. If
Economizer Option Is Used
The Economizer Actuator
VA load Must Also Be
Considered When Sizing

Main Board Wiring
Notes:
1.) Connect FRP Tubing To The High Pressure
Port (Bottom Tube) Of The Staic Pressure
Transducer And Route The Tubing To The
Static Pressure Pickup Probe Location. Leave
The Port Marked “LO” Open To Atmosphere.
2.) The Static Pressure Pickup Probe Should
Ideally Be Mounted With The Probe Pointing
At A 90 Degree Angle To The Supply Air Flow
Direction. It Should Be Located In A Straight
Section Of The Supply Air Duct At A Distance
From The Unit Discharge That Is Approximately
Equal To 2/3 The Length Of The Longest
Supply Air Duct Run. Also Ideally The Probe
Should Be Located Not Less Than 3 Duct
Diameters Downstream And 2 Duct Diameters
Upstream Of Any Elbow Or Takeoff In The
Ductwork.
