Fan Off Delay – Time delay in which the fan will continue run
after being commanded off.
Range = 10 to 300 sec
Default = 90 sec
Minimum Cooling SAT – The supply air temperature must re-
main above this value to allow cooling with the economizer
and/or compressors. There is 5°F plus and minus deadband to
this point. If the SAT falls below this value during cooling a
compressor stage will be removed and/or the economizer will
return to minimum position.
Range = 45 to 75°F
Default = 50°F
Maximum Heating SAT – The supply air temperature must
remain below this value to allow heating. There is 5°F plus and
minus deadband to this point. If the SAT falls below this value
during heating the heat stages will begin to decrease until the
SAT has dropped below this value.
Range = 85 to 150°F
Default = 120°F
Vent Dmpr Pos / DCV Min Pos – Minimum damper position
for ventilation during the occupied period when the fan is oper-
ating at full speed.
Range = 0 to 100% open
Default = 20% open
Economizer Purge Min Pos – The damper position used
during the Pre-Occupancy Purge cycle prior to occupancy
when Pre-Occupancy purge is active.
Range = 0 to 100% open
Default = 40% open
Low Fan Econ Min Pos – The minimum damper position
used for ventilation during the occupied period when the fan is
operating at it's lowest speed.
Range = 0 to 100% open
Default = 33% open
NOTE: This setpoint is only applicable if the Fan Type is set to
Variable Speed or 2-Speed.
DCV Max Vent Damper Pos – This is the greatest position
the economizer can open to while trying to control the indoor
air quality levels.
Range = 0 to 75% open
Default = 50% open
Supply Fan Service Alarm Timer – The timer set for the
Supply Fan Runtime Alarm. After the number of hours set on
this point is exceeded the corresponding alarm will be generat-
ed, and must be manually cleared in the maintenance menu af-
ter the maintenance has been completed. The timer will then
begin counting its runtime again for the next due maintenance.
Range = 0 to 9999 hr
Default = 600 hr
NOTE: If set to 0 hr this setpoint is disabled and its alarm will
never be generated.
Comp 1 Service Alarm Timer – The timer set for the Com-
pressor 1 Runtime Alarm. After the number of hours set on this
point is exceeded the corresponding alarm will be generated,
and must be manually cleared in the maintenance menu after
the maintenance has been completed. The timer will then begin
counting its runtime again for the next due maintenance.
Range = 0 to 9999 hr
Default = 0 hr
NOTE: Default = 0 hours, if set = 0 hr this point is disabled and its
alarm will never be generated.
Comp 2 Service Alarm Timer – The timer set for the Com-
pressor 2 Runtime Alarm. After the number of hours set on this
point is exceeded the corresponding alarm will be generated,
and must be manually cleared in the maintenance menu after
the maintenance has been completed. The timer will then begin
counting its runtime again for the next due maintenance.
Range = 0 to 9999 hr
Default = 0 hr
NOTE: Default = 0 hours, if set = 0 hr this point is disabled and its
alarm will never be generated.
Filter Service Alarm Timer – The timer set for the Dirty Fil-
ter Alarm. After the number of hours set on this point is ex-
ceeded the corresponding alarm will be generated, and must be
manually cleared in the maintenance menu after the mainte-
nance has been completed. The timer will then begin counting
its runtime again for the next due maintenance.
Range = 0 to 9999 hr
Default = 600 hr
NOTE: Default = 600 hours, if set = 0 hr this point is disabled and
its alarm will never be generated.
Pushbutton Override – Set to enable or disable the pushbutton
override function of the locally installed space sensor.
Range = Disable/Enable
Default = Enable
Door Alarm Delay – Determines the amount of delay before a
door alarm is generated.
Range = 0 to 3600 seconds
Default = 60 seconds
Setpoint Adjustment – Set to enable or disable the setpoint
adjustment function of the locally installed space sensor.
Range = Disable/Enable
Default = Enable
Setpoint Adjustment Range – Sets the slider range of a space
sensor (with built in function). The slider is used to offset the
control setpoint.
Range = 0 to 5°F
Default = 5°F
Cooling Lockout Temperature – This defines the minimum
outdoor air temperature that cooling mode can be enabled and
run. If the OAT falls below this number during cooling the
compressors will be de-energized.
Range = –65 to 80°F
Default = 45°F
Economizer High OAT Lockout Temp – If the outdoor air
temperature rises above this value, economizer cooling will be
disabled and dampers will return and stay at minimum posi-
tion.
Range = 55 to 80°F
Default = 75°F
Heating Lockout Temperature – This defines the maximum
outdoor air temperature that heating mode can be enabled and
run. If the OAT rises above this number during heating the heat
stages will be de-energized.
Range = 35 to 150°F
Default = 65°F
Pre-Occupancy Purge – Enables or disables the use of a purge
cycle immediately prior to the start of a scheduled occupied
period.
Range = Enable/Disable
Default = Disable
