4.2.6 CA Temperature Sensor
The CA Temperature sensor is automatically enabled if the heating and/or cooling is enabled. If
it is not connected, an alarm will occur. If your unit was ordered with heating and/or cooling, the
supply temperature sensor should be included but may need to be installed down the duct to
prevent cycling of heating or cooling. The sensor uses a special curve and cannot be swapped
with standard T2 or T3 NTC sensors.
UNIT CONFIGURATION
NOTE: When wiring
sensor, do not wire
directly to the
expansion module;
wire to the X3 terminal
block, see Figure 4.2.0.
