Maintenance Screen —
The Maintenance Screen is
used to service the PremierLink™ controller. See Table 15.
THERMOSTAT CONTROL — Indicates the result of the
configuration decision to control in the thermostat or sensor
mode.
Thermostat
Control: Display Range: No/Yes
Default Value: Yes
Network Access: Read Only
OCCUPIED — The Occupied point indicates whether or not
the controller is operating in the Occupied mode.
Occupied: Display Range: No/Yes
Default Value: No
Network Access: Read/Write
TIMED OVERRIDE IN EFFECT — The Timed Override In
Effect point shows if a timed override is currently in effect.
Timed Override
in Effect: Display Range: No/Yes
Default Value: No
Network Access: Read Only
START BIAS TIME — The Start Bias Time, in minutes, is
calculated by the controller during the unoccupied period (as
needed) to bring the temperature up or down to the set point
under the optimum start routine. The start time bias for heat
and cool are configurable. This value will be reported to the
Linkage Thermostat if it is used. It cannot be used with Global
Scheduling.
Start Bias Time: Display Units: Minutes
Display Range: 0 to 180
Default Value: 0
Network Access: Read Only
HEAT — The Heat point shows if there is a demand for heat in
the space. The space temperature must be below the Occupied
Low or Unoccupied Low set point.
NOTE: When a control mode ends, “NO” mode must be com-
pleted before opposite mode can begin.
Heat: Display Range: No/Yes
Default Value: No
Network Access: None
COOL — The Cool point shows if there is a demand for cool-
ing in the space. The space temperature must be above the
Occupied High or Unoccupied High set point.
NOTE: When a control mode ends, “NO” mode must be com-
pleted before opposite mode can begin.
Cool: Display Range: No/Yes
Default Value: No
Network Access: None
IAQ CONTROL — Indicates weather or not IAQ control is
active in the controller. IAQ control of the minimum damper
position is active whenever the configured parameters for the
IAQ PID calculate a minimum position greater than the config-
ured economizer minimum position.
IAQ Control: Display Range: No/Yes
Default Value: No
Network Access: Read Only
DEMAND LIMIT — Indicates that a command has been
received to limit capacity or reduce capacity of the heating or
cooling.
Demand Limit: Display Range: No/Yes
Default Value: No
Network Access: Read Only
TEMP COMPENSATED START — Indicates that the con-
troller has started the equipment prior to occupancy in order to
be at the occupied set points at the start of occupancy.
Temp
Compensated
Start: Display Range: No/Yes
Default Value: No
Network Access: Read Only
IAQ PRE-OCCUPANCY PURGE — Indicates that the pre-
occupancy purge mode is currently active.
IAQ
Pre-occupancy
Purge: Display Range: No/Yes
Default Value: No
Network Access: Read Only
UNOCCUPIED FREE COOLING — Indicates that unoccu-
pied free cooling is in effect.
Unoccupied Free
Cooling: Display Range: No/Yes
Default Value: No
Network Access: Read Only
FIRE SHUTDOWN — Indicates (in a sensor mode) that the
Fire shutdown input has been sensed. This will also cause the
supply fan and heating and cooling to be turned off.
Fire Shutdown: Display Range: No/Yes
Default Value: No
Network Access: Read/Write
LINKAGE CONTROL — Indicates if the controller is receiv-
ing linkage communication.
Linkage Control: Display Range: No/Yes
Default Value: No
Network Access: Read/Write
FIELD/STARTUP TEST — This point is used to enable a
controller field test. When forced to Yes, the controller will per-
form a test of all outputs and reset to “NO” at end of test. The
test may be aborted at any time by forcing value to NO.
Field/Startup
Test: Display Range: No/Yes
Default Value: No
Network Access: Read/Write
HEAT SUBMASTER REFERENCE — When in sensor
mode, the Heat Submaster Reference point displays the supply
air temperature calculated by the heating PID loop. This value
is compared to the actual supply air temperature to determine
the number of required stages. When in the thermostat mode,
the value displayed is zero.
Heat Submaster
Reference: Display Units: Degrees F (Degrees C)
Display Range: 40.0 to 150.0
Default Value: 40
Network Access: Read Only
COOL SUBMASTER REFERENCE — The Cool Submas-
ter Reference point displays the supply air temperature calcu-
lated by the cooling PID loop when in sensor mode. This value
is compared to the actual supply air temperature to determine
the number of required stages. When in the thermostat mode,
the value displayed is zero.
Cool Submaster
Reference: Display Units: Degrees F (Degrees C)
Display Range: 40.0 to 150.0
Default Value: 150
Network Access: Read Only
