of whether or not compressors are tripped on
high/low pressure.
High/Low Pressure Trips Shutdown Unit
If Any Tripped is selected, the unit will shut down
when any compressor on any circuit it tripped on
high/low pressure. If All Tripped is selected, then
the unit will only shut down once all
compressors are tripped on high/low pressure
on all circuits.
Hot Water Case Heat Outside Temperature Enable
When the supply fan is off, the hot water valve
will be enabled at this outdoor air temperature
and will modulate to meet the Hot Water Case
Heat Setpoint.
Hot Water Case Heat Setpoint
When Hot Water Case Heat Control is enabled,
the hot water valve will modulate to maintain this
temperature at the coil temperature sensor.
Hot Water Valve Position When Unit Off
Sets the position that the hot water valve will
drive to when the unit is off. If set to Modulating,
the valve will control to the Hot Water Case Heat
Setpoint. Configure the 10 Volts Opens Hot
Water Valve setpoint first.
Mixed Air Temperature
The temperature reading from the mixed air
temperature sensor. This is wired to U7 on the
DDC2 I/O module.
Modulating Heat Output
The percentage of output of gas, hot water, or
steam heating. The control module or actuator is
wired to AO3 on the DDC1 I/O module.
Morning Warm Up Enable
Enables and disables the Morning Warm Up
function.
Morning Warm Up Status
Indicates whether or not the unit is currently in
the Morning Warm Up mode.
Morning Warm Up Type
Indicates whether or not Morning Warm Up
exists in the unit’s software.
Night Purge Enable
Indicates whether the system is currently in night
purge mode.
Night Purge Type
Indicates whether or not the Night Purge feature
is installed.
Occupancy Controlled By
Indicates the source of the occupancy command
currently used by the unit: unoccupied, external
input, schedule, optimal start/stop, BAS, or
timed override.
Occupancy Schedule
The occupancy state as determined from the
unit schedule.
Occupancy Status
The current occupancy mode of the controller.
Optimal Start Enable
This point is used to select whether the unit will
allow the optimal start functionality. Optimal start
calculates the system start time based on
historical data including space temperature,
space setpoint, and outdoor air temperature.
Optimal Start/Stop Earliest Start Time
The earliest time of day for the system to start if
needed.
Optimal Start/Stop Earliest Stop Time
The earliest time of day for the system to stop if
needed.
Optimal Stop Enable
This point is used to select whether the unit will
allow the optimal stop functionality. Optimal stop
calculates the system stop time based on
historical data including space temperature,
space setpoint, and outdoor air temperature.
Outdoor Air Damper Maximum Position
The maximum position of the damper during
occupied operation.
Outdoor Air Damper Minimum Position
The minimum position of the damper during
occupied operation.
Outdoor Air Dewpoint Deadband
Adjusts the threshold the unit uses to determine
whether dehumidification is enabled based on
the Outdoor Dewpoint. Dehumidification is not
requested if the Outdoor Dewpoint is less than
(Outdoor Dewpoint Setpoint – Outdoor Air
Dewpoint Deadband).
