• 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.MICRO PROCESSOR-BASED DISCHARGE WATE| Application Size | 0 Heat / 6 Cool |
