Overview
Controls discharge water temperature in reciprocating chiller and cooling tower applications.

Loading ...
Features

• The W7100G maintains average discharge water temperature by staging on and off compressors, unloaders of water tower fans as required.
• Provides up to six stages of cooling.
• Use W7101A for expanding up to 10 cooling stages.
• Advanced proportional plus integral microprocessor control algorithm minimizes droop.
• Soft start to minimize compressor cycling during system start up.
• Adjustable minimum on/off timing and time delay between stages of either 30 or 60 seconds.
• Reset of discharge water temperature based on either outdoor air or space sensor signal.
• Use C7170 Sensor for sensing water temperature.
• LEDs indicate which stages of cooling are energized.
• Use S963B Potentiometer for remote set point capability.
