11
ECONOMIZER ACTIVE (NOT USED) — The Economizer
Active point displays the status of the economizer for free cool-
ing. When the outdoor conditions match the desired indoor
conditions, the economizer will be enabled for outdoor air
assisted cooling.
Economizer
Active: Display Units: Discrete ASCII
Default Value: No
Display Range: No/Yes
Network Access: Read Only
SUPPLY FAN RELAY — This point displays the command-
ed state of the Supply Fan Relay.
Supply Fan
Relay: Display Units: Discrete ASCII
Default Value: Off
Display Range: Off/On
Network Access: Read/Write
SUPPLY FAN STATUS — This point displays the Supply
Fan status if the controller is configured to receive input from
the Supply Fan. Otherwise this point will display the output
state of the Supply Fan Relay. This mode can only be used
when the controller is in sensor control mode.
Supply Fan
Status: Display Units: Discrete ASCII
Default Value: Off
Display Range: Off/On
Network Access: Read Only
ECONOMIZER DAMPER POSITION (NOT USED) —
This point displays the current commanded damper position of
the economizer 4 to 20 mA on the J-9 connector. The 4 to
20 mA signal is scaled linearly over the range of 0 to 100% of
the Supply Fan Relay.
NOTE: Although not normally used for Aquazone™ applica-
tions, this output may be used to control a fresh-air damper for
a demand control ventilation strategy.
Economizer
Position: Display Units: % Open
Default Value: 0
Display Range: 0 to 100
Network Access: Read/Write
CURRENT MINIMUM DAMPER POSITION — This point
displays the current minimum damper position if an Indoor Air
Quality routine is not active. If an Indoor Air Quality sensor is
installed and the differential air quality set point has been
exceeded, this point will display the current calculated mini-
mum position deemed necessary to maintain the air quality in
the space.
Current Minimum
Damper Position: Display Units: % Open
Default Value: 0
Display Range: 0 to 100
Network Access: Read Only
FILTER STATUS — The filter status point will be shown as
“CLEAN” until the run time of the fan exceeds the configured
Filter Timer Hours. When the user-configured Filter Timer
Hours has been exceeded, the Filter Status will display
“DIRTY” and a CCN alarm will be generated. Forcing the
point to “CLEAN” will clear the alarm condition and will reset
the timer. (Setting the configured filter timer value to zero will
provide the same function.) The value of the timer is stored in
EEPROM to protect it in the event of a power failure. This is
done periodically every 24 hours. The filter timer function only
operates if the configured filter timer value (FLTTMR) is a
non-zero number.
Filter Status: Display Units: Discrete ASCII
Default Value: Clean
Display Range: Clean/Dirty
Network Access: Read/Write
REMOTE OCCUPIED MODE — This point displays the
status of the remote time clock input. This input is only avail-
able when the controller is being used in sensor control mode.
When the Remote Start point is on, and the zone controller is
not controlled by a Linkage Thermostat, the controller will
function in an occupied mode. When the Remote Start point is
off, the controller will revert to its own occupancy schedule.
Remote
Occupied Mode: Display Units: Discrete ASCII
Default Value: Off
Display Range: Off/On
Network Access: Read/Write
HEAT STAGE 1 — The Heat Stage 1 point provides the state
of the Heating 1 output.
Heating Stage 1: Display Units: Discrete ASCII
Default Value: Off
Display Range: Off/On
Network Access: Read Only
HEAT STAGE 2 — The Heat Stage 2 point provides the state
of the Heating 2 output.
Heating Stage 2: Display Units: Discrete ASCII
Default Value: Off
Display Range: Off/On
Network Access: Read Only
HEAT STAGE 3, EXHAUST FAN, OR REVERSING
VALVE — This point displays the commanded state of auxil-
iary output. This output can be configured to control a third
stage of heat, an exhaust fan, or a reversing valve on some heat
pump units.
In the exhaust fan mode with continuous exhaust con-
figured, this point may control a bank of lights or another
indicator that should remain ON whenever the controller is in
the occupied mode.
Heat 3, Exhaust,
Rev Valve: Display Units: Discrete ASCII
Default Value: Off
Display Range: Off/On
Network Access: Read Only
ENTHALPY (NOT USED) — This point displays the cur-
rent status of an outdoor air or differential enthalpy input. This
point may be broadcast to other controllers or received from
a controller which supports global broadcast of the ENTH
variable.
Enthalpy: Display Units: Discrete ASCII
Default Value: High
Display Range: High/Low
Network Access: Read/Write
INDOOR AIR QUALITY (IAQ) — The Air Quality point
displays the indoor air quality reading from a CO
2
sensor
installed in the space. The CO
2
sensor maintains differential
indoor air quality for demand control ventilation per ASHRAE
Standard 62-1999. The controller can be configured to generate
an alarm when the control is in occupied mode and the CO
2
level exceeds the high or low limit set.
Indoor Air
Quality (ppm): Display Units: None shown (parts per
million implied)
Default Value: 0
Display Range: 0 to 5000
Network Access: Read/Write
