What is the control logic between the energy saver and auxiliary cooling coils and the compressor(s)?
Energy Saver/Auxiliary Chilled Water Cooling will be available whenever the incoming water supply is below the setpoint of the Water Sensing Changeover Thermostat. The Energy Saver/Auxiliary Chilled Water mode will operate only in a two (2) degree range. The range is between the return air setpoint plus deadband and two (2) degrees above this. If the temperature rises above this range, Energy Saver/Auxiliary Chilled Water Cooling will be inhibited for one (1) hour and DX cooling only will be available. After one (1) hour, it will try Energy Saver/Auxiliary Chilled Cooling again. The chilled water valve proportionally opens 10% for each 0.1ยบ F above the Temperature Setpoint plus Temperature Deadband. The chilled water valve responds to a change of the return air temperature after each adjustment period. Then a change is made to the setpoint, the chilled water valve will delay its response for five (5) minutes, then will respond after each adjustment period. If the temperature is consist
