Outlet Temperature Sensor
Upon sensing the “Loss of Water Flow” from the chiller, the master control will turn OFF the
re-circulating pump and activate the alarm. The master control will deactivate the failure
chiller from the temperature scheme. The chiller controller also reads the high pressure of
each refrigeration circuit.
The reads determine the number of fans to activate to control head pressure at a set point.
