COOLING TOWER LEVEL CONTROL

    The cooling tower for chiller 4 & the yard towers for chillers 1&2 have had the float valves removed and are under Metasys control (modulating ball valve near the make-up water meter). The tower level reading is the distance from the water surface to the ultrasonic sensors face. I have decided to use the default settings so, ten inches is the min & forty inches is the max range. Just by luck, both setpoints ended up at 15″. The new points can be found under chiller #4 & yard towers, setpoints will be maintained weather it’s running or not. There will be a enable\disable point for the operator in the future.
