INFORMATION
If the booster heater always takes over the DHW heat load due to setting Priority
schedule to A/C, electricity consumption will be considerably higher. For the
months where A/C heating/cooling is less important, it is recommended to set the
Priority schedule to DHW.
INFORMATION
If DHW is set as priority and frequent DHW operation is expected, there is risk for
comfort problem due to interruption of A/C operation. For the months where A/C
heating/cooling is more important, it is recommended to set the Priority
schedule to A/C.
