Trigger Scenario
1. Local Space temp as the main
control and sensor fault is detected.
2. Remote Space temp as the main
control. sensor fault is detected.
3. Multi space temp as the main control.
All/Some of the temp sources have
sensor fault detected.
4. There is a network input space
temperature, and the network input
space temperature value is below -40°F
or above 150°F.
The space temperature has exceeded
the defined range (you can set this
range on the alarm limits screen). This
applies to whichever sensor is acting as
the space temperature sensor,
including network inputs.
1. The Local Space Humidity sensor is
used as the primary data source for
control, and a fault has been detected
in this sensor.
2. The Remote Space Humidity sensor
is used as the primary data source for
control, and a fault has been detected
in this sensor.
3. Multiple Space Humidity sensors are
used as the primary data sources for
control, and faults have been detected
in one or more of these sensors.
The thermostat has been disconnected
from power for an extended period,
causing the real-time clock (RTC) to
reset.
The user can set up the DIO/UIO
terminal as a binary input to monitor
water leakage. Upon activation of this
input, a drain pan alarm will be initiated.
Should a fault be detected with the pipe
sensor, or if the temperature of the pipe
falls outside the specified range, the
system will respond accordingly.
Configurable range settings can be
adjusted in the 'Alarm Limits' section.
High Limit: Default at 180°F (range:
70°F to 220°F).
Low Limit: Default at 40°F (range: 30°F
to 60°F).
Action
1. If the sensor is utilized for the
control loop and network input of
temperature is available, the
thermostat will only trigger an
alarm.
2. If the sensor is used for the
control loop and the network input
of temperature/humidity is not
available, the thermostat will turn
off all output controls for the
Heating and Cooling equipment.
The fan will continue to operate
normally.
The thermostat will only trigger an
alarm.
1. If the sensor is utilized for control
loops and network input for
temperature/humidity is available,
the thermostat will only trigger an
alarm.
2. If network input for temperature/
humidity is not available, the
thermostat will disable all control
functions (e.g., humidity control for
humidification or dehumidification)
related to the malfunctioning
sensor.
Ask the user to update the date and
time.
User can configure the operation
would be taken when drain pan
alarm is detected:
1, disable cooling. 2, disable
heating. 3, disable fan
Both heating and cooling functions
will be deactivated.
