Supply Air Temperature Alarm
The control has 2 configurable alarm limits for supply air tempera-
ture. The control verifies that the supply air temperature is within
operating range (between high and low limits) when the compres-
sor or auxiliary heat is operating. If the air temperature rises above
or falls below the appropriate limits, and this lasts for more than
5 minutes, an alarm is generated.
Fan Status Alarm
The control generates a fan status alarm if the fan status input de-
tects the fan is OFF after any fan speed output has been enabled. A
30-second alarm delay is used to allow the fan to start operation
before an alarm condition is detected. The control monitors the fan
output and if the fan is operating at any speed, the fan status must
detect the fan is operating.
Compressor Status Alarm
The control generates a compressor failure alarm if the compres-
sor status input detects the compressor is OFF after the compres-
sor output has been energized. A 6-minute alarm delay is used to
allow the compressor to start (prevents alarms due to timeguard
operation) before an alarm condition is detected. The control mon-
itors the compressor output and if the compressor output is ener-
gized, the compressor status input must detect the compressor
operation.
Filter Status Alarm
The control provides the ability to generate a dirty filter alarm af-
ter the number of fan run hours exceeds a configurable filter alarm
timer limit. The control monitors the fan output and if the fan is
operating at any speed, it accumulates run time. If the fan run time
hours exceed the configurable limit, an alarm is generated. To re-
set the alarm timer after the alarm has been generated, a Reset Fil-
ter Alarm input is provided. You can disable the filter alarm by set-
ting the Filter Alarm Timer Delay to 0 (factory default).
Indoor Air Quality Alarm
The control provides the ability to generate a high CO
2
level alarm
during occupied periods when the CO
2
sensor value exceeds the
adjustable limit. When a transition from unoccupied to occupied
occurs, or the occupied alarm limit is changed to a value that caus-
es an alarm condition to occur, the control will automatically cal-
culate an alarm delay (equivalent to the configured delay time in
minutes/ppm, times the error that occurred, + 15 minutes). This
prevents nuisance alarms from occurring when occupancy chang-
es or the setpoint is changed. You can disable the IAQ alarm by
setting Occupied High IAQ Alarm Limit to 0.
Relative Humidity Alarm
The control provides the ability to generate an alarm when the
space relative humidity exceeds the alarm setpoint. Separate occu-
pied and unoccupied high humidity alarm setpoints are provided.
The control provides a 5-minute alarm delay during unoccupied
periods. During occupied periods, the controller uses the occupied
high RH alarm limit. When an occupancy transition from unoccu-
pied to occupied occurs, or the occupied high alarm limit is low-
ered, causing an alarm condition to occur, the control automatical-
ly calculates an alarm delay (equivalent to the configured delay
time in minutes/% RH, times the humidity error condition that oc-
curred, + 15 minutes). This prevents nuisance alarms when an oc-
cupancy change occurs and allows time for the unit to correct an
alarming humidity condition.
Source Water Linkage Failure Alarm (if Source Water Link-
age was active)
The control generates a Source Water Linkage failure alarm if
Linkage fails after once being active. The Linkage status is moni-
tored and if it fails to be updated from the Loop controller, then a
Source Water Linkage alarm is generated. There is a 6-minute
alarm delay to prevent false alarms.
NOTE: You can reset this alarm only by re-establishing Linkage
and correcting the condition that caused the Linkage failure, or by
momentarily setting the Shutdown point to Active.
Airside Linkage Failure Alarm (if Airside Linkage was
active)
The control generates an Airside Linkage failure alarm if Linkage
fails after once being active. The Linkage status is monitored and
if it fails to be updated from the master zone controller, then an
Airside Linkage alarm is generated. There is a 6-minute alarm de-
lay to prevent false alarms.
NOTE: You can reset this alarm only by re-establishing Linkage
and correcting the condition that caused the Linkage failure, or by
momentarily setting the Shutdown point to Active.
OAT Sensor Alarm (if Network OA Temperature was active)
The control generates an OAT Sensor failure alarm if the value of
OAT fails to be updated through the network after once being ac-
tive. The update status is monitored and if it fails to be updated,
then an OAT sensor alarm is generated. There is an alarm delay
(approximately 1 hour) to prevent false alarms, while minimizing
the required update rate for OAT.
NOTE: You can reset this alarm by momentarily setting the Shut-
down point to Active.
SPT Sensor Alarm (if SPT sensor was active)
The control generates an SPT sensor failure alarm if the SPT sen-
sor fails to communicate with the control for 5 minutes or greater.
The update status is monitored and if it fails to be updated, then an
SPT sensor alarm is generated.
ZS Sensor Alarm (if ZS sensor was active)
The control generates a ZS sensor failure alarm if the ZS sensor
fails to communicate with the control for 5 minutes or greater. The
update status is monitored and if it fails to be updated, then a ZS
sensor alarm is generated.
UPM Alarm - Hard lockout status
The control generates Alarm when Hard lockout Alarm is active
on UPM board. Configurable 2 or 4 soft lockout alarms on UPM
board before unit enters to hard lock out. Soft lockout alarm histo-
ry is available via controller.
Low Water Flow Alarm
The control monitors differential pressure switch (water flow
switch), and generates alarm if water flow is not met.
Air Side Delta T Alarm
The control has 4 configurable alarm limits for Air Side Delta T.
The control verifies that the calculates delta T based on Return and
Supply Air temperatures reading and verifies if it operates within
configured ranged (between high and low limits) for the specific
operating mode (heating or cooling) before energizing the
compressor.
Source Water Valve Alarm
The control generates alarm if communication with Act Net de-
vice is lost.
Water Side Delta T Alarm
The control has 4 configurable alarm limits for Source water
Delta T.
The control verifies that the calculates delta T based on Entering
and Leaving water temperatures reading and verifies if it operates
within configured ranged (between high and low limits) for the
specific operating mode (heating or cooling) before energizing the
compressor.
Entering Water Temperature Alarm
The control has 4 configurable alarm limits for Entering Water
temperature.
The control verifies that the entering water temperature is within
operating range (between high and low limits) for the specific op-
erating mode (heating or cooling) before energizing the compres-
sor. Once the compressor is started, the entering water temperature
is further monitored to verify that it is within limits to insure suffi-
cient water is flowing through the coil. If the entering water
