OA DAMPER OVERRIDE/VFD OVERRIDE – If the unit is equipped with a VFD
this will display ‘VFD OVERRIDE’. If the unit is equipped with mixed air dampers
‘OA DAMPER OVERRIDE’ will be displayed. This option allows you to override the
calculated damper position or VFD speed for building pressure control. By
selecting ‘YES’ building pressure control will be overridden and the dampers or
VFD will be locked to the value entered in the option below. Selecting ‘NO’ allows
for automatic damper position or VFD speed and building pressure control. When
selecting ‘YES’ the text is displayed in orange as a reminder you are in override
control.
MANUAL DAMPER/MANUAL VFD SPEED – This displays the current damper
position or VFD speed in black when not in override. Pressing this button will
allow you to enter an override value from 0% to 100%. When in override mode
the override value is displayed in orange text as a reminder.
OCC OVERRIDE – This displays the current occupancy command and
occupancy status. Pressing this button will allow you to select AUTO SCHEDULE,
MAN OCCUPIED or MAN UNOCCUPIED. By selecting ‘AUTO SCHEDULE’ the unit
will follow the occupied and unoccupied times entered in the schedule. By
selecting ‘MAN OCCUPIED’ the unit will ignore the schedule and permanently
assume the occupied status. By selecting ‘MAN UNOCCUPIED’ the system will
ignore the schedule and permanently assume the unoccupied status.
PRESS FOR BURNER RESET – If the unit is experiencing a Burner Lockout
Alarm the text will display ‘BURNER LOCKOUT’ in red. If the burner is operating
normally the text will display ‘NORMAL’ in black. If there is a burner lockout
alarm, press this button to reset the burner and attempt ignition again.
CURRENT SET POINT – This is the current set point the unit is controlling
to. If you are in Space Temperature Control, this is your current occupied or
unoccupied space temperature set point. If you are in Discharge Temperature
Control, this is your current occupied or unoccupied discharge temperature set
point.
SPACE TEMPERATURE/DISCHARGE TEMPERATURE – If you are using Space
Temperature Control, this is the current space temperature as sensed by the
space temperature sensor. If you are using Discharge Temperature Control, this is
the current discharge temperature the unit is providing to the space.
BUILDING PRESSURE – This is the current building pressure, as sensed by
the building pressure transmitter.
