MUA Unit
If you need to set up your HVAC unit for MUA operation, use the fol-
lowing values:
Confi guration Section
Screen #1—Duct Static Pressure Control = “NO”
Screen #3—HVAC Mode Enable = “Entering Air”
Screen #4—HVAC Reset Source = “No Reset”
Can be confi gured for Reset; see the Supply Air Setpoint Reset
section that follows before confi guring.
Screen #6—Dehumidifi cation Control = “YES”
Only if the unit is equipped for Dehumidifi cation.
Screen #7—Dehumidifi cation Priority = “YES”
Screen #8—Dehumidifi cation Unoccupied = “NO”
Screen #9—Entering Air Humidity Sensor = “YES”
Only if equipped with an Entering Air Humidity Sensor for
Dehumidifi cation.
Screen #14—Proof of Flow Input = “YES”
Only if equipped with a Proof of Flow Switch.
Screen #28— Emergency Shutdown Input = “YES”
Only if a Smoke Detector, Firestat, or other Shutdown device is
connected to the SA Controller.
Screens #41 through #60 = Refer to the AAON ® wiring diagram
inside the unit before confi guring onboard and expansion board
relays.
Heat Pump
Heat Pumps can be confi gured as VAV, CAV, or MUA. Confi guration
Screens #26 and #27 are used to confi gure the Heat Pump. A Relay Out-
put must be confi gured for a Reversing Valve on Screens #41 through
#60 whether the Reversing Valve is to be activated during Heating or
Cooling operation. When using AAON
® equipment, if the equipment
is an AAON ® packaged unit, the Reversing Valve activates during
Heating operation.
Confi guration Section
Screen #26—Heat Pump Control = “YES”
Screen #27—Reversing Valve Active During Heat/Cool =
“0=Heat” if the Reversing Valve should energize for Heating
operation; “1=Cool” if the Reversing Valve should energize for
Cooling operation.
Screens #41 through #60 = Refer to the AAON ® wiring diagram
inside the unit before confi guring on-board and expansion board
relays.
