CAUTION: The Shraeder port used for installation of the
suction pressure transducer should be located in a vertical
position of the suction line to prevent refrigerant oil from
accumulating in the sensor.
NOTE: If there are two Compressors on a single circuit
(a tandem circuit), Suction Pressure 2, Head
Pressure 2, and Condenser Signal 2 would not be
used.
Head Pressure Control
The Head Pressure Transducers are used to measure Head Pressure at
the discharge line. This Head Pressure is used to drive the Condenser
Fans with a 0-10 VDC output signal or valve with a 2-10 VDC output
signal to maintain a given Head Pressure Setpoint.
Compressor Discharge Sensors
The Digital Compressor Discharge Temperature Sensor monitors
the discharge temperature from the Digital Compressor to protect
against overheating.
Leaving Water Temperature Sensor
The Leaving Water Temperature Sensor is used to measure the
Leaving Water Temperature when used on a WSHP unit.
