Greenheck Low Voltage (24 VAC/ VDC) Sure-Aire Pressure Controller (476092) - Manual (Page 7)

7 Sure-Aire™ Flow Monitoring System
Temperature Sensor
Interconnect the remote temperature sensor by
connecting the temperature sensor to pins 4 and 5 of
TB2. The Remote Temperature Sensor will adjust the
air density value in the controller based on the sensor
measurement when Temperature Compensation is set
to ‘Yes’. This density compensation will affect the flow
rate accordingly. If Temperature Compensation is set to
‘No’, the air density value will be a function of standard
air (70°F/21°C).
