button to access the
Confi guration Setpoints Screens.
Box Confi guration

cooling only, heating/cooling changeover, series fan powered, or paral-
lel fan powered.
Proportional Heat [2-10 vdc]
Touch the square if this unit has 2-10 vdc proportional heat. Leave blank
for 0-10 vdc operation.
This Box Needs the Main Fan Status
Touch the square if this unit needs Main Fan status. This setting only
applies to the unoccupied mode of operation. Choose this setting to
activate the heating stages only when the main fan is operating on non-
fan terminal units.

For series fan terminal units, if this setting is selected, the series box fan
will only run when the main HVAC unit fan is running or when a space
heating demand is made. If this setting is NOT selected, the series box
fan will only run when a space heating demand is made. This setting
has no effect on the parallel fl ow fan terminal unit.
Damper is Reverse Acting [Opens CCW]
Touch the square if this unit’s damper is reverse acting (opens counter-
clockwise).
Voting Zone on Zoned Systems
Touch the square if this unit is a voting zone.
Allow Box Heat to remain on in HVAC Heat Mode
Touch the square to have box heat remain on in HVAC heat mode. This
will allow the Heating Relay’s Controlling Box Heat to remain on even
when the AHU is in Supply Air Heating Mode. This is used as a method
to provide supplemental heat if for some reason the AHU heat cannot
satisfy the heating demand.
No Air Valve Control [ Dump Zone]
A Dump Zone is used when you want to control a duct heater or base-
board heater independently. A VAV/Zone Controller board with a relay
expansion board is used for this purpose. No damper or actuator is used.
Touch the square if this unit has no air valve control (Dump Zone). If
you need to control an auxiliary heater, do not select this option.
Use Broadcast from HVAC Unit on Separate Loop
Touch the square if this unit is installed on a system with one HVAC
unit having multiple VAV loops.
