• Return temperature range indicates the amount of change in inlet water temperature of the chiller unit to determine thermo ON after
thermo OFF. (In the case of cooling: amount of temperature increase; in the case of heating: amount of temperature decrease)
• It is possible to change settings locally depending on usage purpose, but since the necessary volume of water will change, change the
settings only upon confirmation of the amount of the retained volume of water in the entire local system.
