A working Compressor Dome Temperature Sensor is
required for:
• Protection (High/Low Temperature)
• Preheating (Sump Heat)
• Outdoor EEV Control
• Diagnostics; Reverse rotation, Flooding, Charge
Level
The Dome Temperature Sensor control contains an
NTC thermistor input for sensing the Compressor
Dome Temperature. The thermistor has a nominal
resistance of § 10k ohms at 75°F. The minimum range
required for the Dome Temperature input is —31°F to
302°F. when measured across pins 1 and 10.
NNoottee:: Secure Installation of Dome Sensor is required
for reliable compressor & system operation.
