x5
Exhaust Interlock OAD
Min Position set point
EOAD
Adjust OA damper position above which the exhaust fan output will be energized. There is a xed –5%
differential associated with this set point.
RW x 99%
x6
Energize Exhaust Fan
OAD Set point
OADE Adjust OA damper minimum position when the exhaust interlock input is energized. RW x 12%
x7
OAD Max Position Set
point
OAMX Adjust OA damper maximum position. RW x 99%
x8
OAD Lockout Enable
Set OA damper lockout feature status: 0 = disable, 1 = enable. (This variable is factory set to 1 when
the unit is ordered as a recirc unit with no OAD.)
RW x 0
x9
OAD Lockout Set
point
OALS
Adjust OA temperature below which the OA damper closes if the OA damper lockout is enabled. (This
variable is factory set to –99°C when the unit is ordered as a recirc unit with no OAD.)

e1
Economizer Enable Set economizer status: 0 = disable, 1 = enable. RW x 1
e2
Economizer OA Temp
Set point
ETS
Adjust economizer OA temperature set point. DO NOT lower this set point below CCLO or you risk
creating a deadband where no cooling occurs.
RW x

Emergency Heat
Set point
EHS Adjust emergency heat set point. RW x
53.6°F

h3
Emergency Heat Shut-
down Conguration
Set emergency heat operation during shutdown, 0 = no emergency heat during shutdown: 1 = allow
emergency heat during shutdown.

a3
Auxiliary Heat
Conguration
Set auxiliary heat type: 0 = N.O. device, 1 = N.C. device. RW x 0
b3
External BI-3 Congu-
ration
Set the function external binary Input 3: 0 = ventilation lockout, 1 = exhaust interlock. RW x 0
b6
External BO-3
Conguration
Set the function of external binary output 3: 0 = exhaust fan on/off signal, 1 = auxiliary heat. RW x 0
cf
Fan Cycling
Conguration
Set space fan cycles (switches off) during occupied, bypass, and standby mode: 2 = continuous, 3 =
cycling.
RW x 2
ce
Filter Alarm Enable Set lter alarm status: 0 = disable, 1 = enable. RW x 0
cr
Reset Filter Alarm Input Enter 1 to clear lter alarm. RW x

c1
Compressor Enable Set compressor status: 0 = disable, 1 = enable. RW x 1
c2
Compressor Cooling
Lockout Set point
CCLO
Adjust compressor cooling lockout set point. When the OA temperature falls below this set point, com-
pressor cooling is not allowed. DO NOT make this setting lower than the factory default. There is a xed
+3.6°F (2°C) differential associated with this set point.
RW x
63.5°F
(17.5°C)
c3
Compressor Heating
Lockout Set point
Adjust compressor heating lockout set point. When the OA temperature falls below
this set point, compressor heating is not allowed and only electric heat will be used.
RW x
25°F
(-4°C)
c6
Compressor Start
Delay
Adjust compressor start delay. Where several units (inductive loads) are connected to the same electri-
cal supply, make this set point unique for every UVC to prevent multiple compressors from energizing at
the same time after a power failure or occupancy change.
RW x 0 sec
sp
Space Temp Sensor
Offset
Adjust this setting to bias the UVC measured space temperature. RW x 0
un
Keypad/display
Temperature Units
Set keypad/display temperature units in English or SI. This set point also effects which unit types dis-
played over Metasys N2 and BACnet MS/TP networks using the appropriate optional communications
modules.
RW x F
1. RW = read and write capable, RO = read only.
2. If a menu value is greater than 2-digits (higher than 99), then will be displayed on the keypad/display.
