DEFINITION
1ST STAGE COOLING SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in
a Constant Volumn unit as the Active SAT Setpoint for 1st Stage cooling operation.
1ST STAGE HEATING SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in
a Constant Volumn unit as the Active SAT Setpoint for 1st Stage heating operation.
2ND STAGE 2 COOLING SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in a
Constant Volumn unit as the Active SAT Setpoint for 2nd Stage cooling operation.
2ND STAGE 2 HEATING SETPOINT
This parameter is programmed through the SETPOINTS key. This value is used in a
Constant Volumn unit as the Active SAT Setpoint for 2nd Stage heating operation.
ACTIVE SLAB CONTROL
This parameter is programmed through the PROGRAM key. This function allows
heat to be turned ON during the transition from Unoccupied to Occupied mode or
Occupied to Unoccupied mode if the under floor conditions of a FlexSys system
are right for the growth of mold and mildew. The choices are USER ENABLED or
USER DISABLED.
ADAPT MORN WARM UP
This parameter is programmed through the PROGRAM key. Adaptive Morning Warm
Up uses the past three days of warm up times and temperatures to calculate the
start time for the current day. This parameter allows the user to USER ENABLED
or USER DISABLED this feature.
BLDG PRESSURE CNTRL OFFSET
This parameter is programmed through the SETPOINTS key. The Unit Controller To
determine when to turn on the exhaust fan. When the exhaust option is configured
for “ON-OFF PRESS CNTRL”.
BUILDING PRESSURE ACTIVE
SETPOINT
This parameter is programmed through the SETPOINTS key. It identifies the control
point for the building pressure.
BUILDING PRESSURE CURRENT
This is the actual pressure in the conditioned space.
BYPASS DAMPER POSITION
This is the actual position of the bypass damper, by percent open, in a FlexSys
unit.
CO
2
LEVEL INSIDE
This is the CO
2
level of the air in the conditioned space.
CO
2
LEVEL OUTSIDE
This is the CO
2
level of the outdoor air.
CO
2
OFFSET CURRENT
This represents the current difference between the “CO
2
LEVEL INSIDE” versus the
“CO
2
LEVEL OUTSIDE”.
CO
2
OFFSET SETPOINT
This parameter is programmed through the SETPOINTS key. The Outside CO
2
level
must be lower than the Indoor CO
2
level plus the CO
2
OFFSET SETPOINT before
the outdoor door damper will start to open for additional ventilation.
COMFORT VENTILATION
This parameter is programmed through the PROGRAM key. This function is only used
on a Constant Volume unit. The Unit Controller monitors the Return Air Temperature
and energizes stages of cooling or heating prior to a demand from the space. This
function is only active when the unit is in the Occupied mode. The choices are USER
ENABLED or USER DISABLED.
COMP SYS 1 STATUS
This is the current operating mode of compressors I and 2. The display will show
Normal - Comp A On, Normal - Comp B On, Normal - Both ON, Normal - Both Off,
Safety Trip, Safety Fault, Safety Lockout, Low Amb Inhibit, Low Suct Temp Unl, High
DP Unload, or User Disabled.
