COMPRESSOR SAFETY When the controller is in
sensor mode, this point can be used to monitor the status of the
compressor trouble output supplied with some equipment.
When the input is detected, the controller will issue a compres-
sor trouble alert on the communications network. Staging will
operate as normal.
Compressor
Safety: Display Units Discrete ASCII
Display Range Off/On
Default Value Off
Network Access Read Only
ROOFTOP MODE This point displays the numeric value
of the Rooftop Mode ASCII point and is used with the LON
Translator for interfacing into third party LON systems.
Rooftop Mode: Display Units Numeric
Default Value 1
Display Range 1-10 (1=OFF,
2=COOL,
3=HEAT,
4=FAN ONLY,
5=UNOCCOOL,
6=UNOCHEAT,
7=WARMUP,
8=FREECOOL,
9=PRESS, 10=EVAC)
Network Access Read Only
LON SETPOINT This point displays the midpoint be-
tween the configured Occupied Low Setpoint and the Occu-
pied High Setpoint. It is used to display the LON Setpoint
when the PremierLink™ controller is used with a LON transla-
tor for interfacing into third party LON Systems.
LON Setpoint: Display Unit degrees F (degrees C)
Default Value 72.0 F
Default Range -40.0 to 245.0 F
Network Access Read/Write
ALARM STATUS This point displays the alarm status of
the PremierLink controller if there is an active alarm. It is pri-
marily used to display the alarm status when used with the
LON translator for interfacing into third party LON systems.
ALARM
STATUS: Units Discrete ASCII
Default Value Normal
Default Range Normal/Alarm
Network Access Read Only
Thermostat Control Input Screen — The Thermo-
stat Control Input Display is used to display the input status of
equipment requests from the thermostat (TSTAT). See
Table 12.
Alarm Service Configuration Screen — The Alarm
Service Configuration (ALARMS) is used to configure the
alarms used on the PremierLink™ controller. See Table 13.
ALARM ROUTING CONTROL — The Alarm Routing
Control indicates which CCN system software or devices will
receive and process alarms sent by the PremierLink controller.
This decision consists of 8 digits which can be set to zero or
one. A setting of one indicates alarms should be sent to this
device. A setting of zero disables alarm processing for that
device. Currently the corresponding digits are configured for
the following devices: first digit is for user interface software
(ComfortWORKS
®
, ComfortVIEW™, BACnet/Modbus
Translator, etc.); second digit is for Autodial Gateway or
Telink; fourth digit is for Alarm Printer Interface Module,
DataLINK™ module; digits 3 and 5 through 8 are unused.
Alarm Routing
Control: Range 00000000 to 1111111
Default Value 00000000
ALARM RE-ALARM TIME This decision is used to con-
figure the number of minutes that will elapse between
re-alarms. A re-alarm occurs when the condition that caused
the initial alarm continues to persist for the number of minutes
specified. Re-alarming continues to occur at the specified
interval until the alarm condition no longer exists.
Re-Alarm Time: Display Units minutes
Display Range 0 to 1440
Default Value 0 (Disabled)
CONTROL TEMPERATURE HYSTERESIS — This con-
figuration defines the range above the high set point and below
the low set point the space temperature must exceed for an
alarm condition to exist during occupied hours.
For example, if the current setpoint is 75 F and the hystere-
sis value is 5° F, an alarm will be generated if space tempera-
ture exceeds the low limit of 70 F or the high limit of 80 F.
Control
Temperature
Hysteresis: Display Units delta degrees F
(delta degrees C)
Range 1.0 to 100.0
Default Value 5.0
CONTROL HUMIDITY HYSTERESIS — This configura-
tion defines the range above the dehumidification set point that
the humidity must exceed to generate an alarm condition. This
value is added to the both the occupied and unoccupied dehu-
midification set points.
Control Humid
Hysteresis: Range –5 to 10 %
Default Value 5 %
SUPPLY AIR TEMPERATURE — LOW LIMIT The
Supply Air Temperature Low Limit alarm is used to monitor
the value of the supply-air temperature within a specified
range. If the supply-air temperature becomes too low, an alarm
condition will exist.
Supply Air
Temperature
Low Limit: Display Units degrees F (degrees C)
Display Range –40.0 to 245.0
Default Value 45.0
SUPPLY AIR TEMPERATURE — HIGH LIMIT — The
Supply Air Temperature High Limit alarm is used to monitor
the value of the supply-air temperature within a specified
range. If the supply-air temperature becomes too high, an alarm
condition will exist.
Supply Air
Temperature
High Limit: Display Units degrees F (degrees C)
Display Range –40.0 to 245.0
Default Value 150.0
INDOOR AIR QUALITY ALERT LIMIT — The Indoor-
Air Quality Alert Limit alarm defines the allowable CO
2
levels
during occupied periods. If the CO
2
levels become too low or
too high during occupied periods, an alarm condition will exist.
Indoor Air Quality
Low Limit: Display Units PPM (implied)
Display Range 0.0 to 5000.0
Default Value 0.0
Indoor Air Quality
High Limit Display Units PPM (implied)
Display Range 0.0 to 5000.0
Default Value 1200.0
IMPORTANT: Forcing this point will cause the configured
Occupied Low and Occupied High set points to change by
equal amounts.
