DVM Chiller Introduction
Water Law Control – Applications where efficiency is increased by resetting the leaving water
temperature based on outside ambient temperature or room temperature
▪
When chiller is configured for standard water temperature range (default) the operating water
temperature range in cooling will not drop below 41°F
▪
When chiller leaving water temperature is controlled by room temperature, a field supplied TP100
external sensor must be used or a signal from a BMS control
