Honeywell W7100G1001 Temperature Controller

Honeywell W7100G1001 Temperature Controller. Controls discharge water temperature in reciprocating chiller and cooling tower applications. 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.
