AC200 - Water Cooled, Air Conditioning Controller
Overview
AC200 is controller for water cooled air conditioners. This instrument monitors the conductivity of water. The water is flushed out when the conductivity crosses a specified set point. This instrument has 4 digit LED display and two keys for programming. Programmable relay outputs for water flushing and fill controlling. AC200 continuously monitors compressor ON time. Water flushing time can be programmed by user. AC200 flushes out the water based on conductivity or time or both (programmable in the instrument.AC200 monitors temperature , water level and conductivity and displays each parameter in the LED display.
