1. when EVU signal is on, the unit operate as below:
DHW mode turn on, the setting temperature will be changed to 70
automatically, and the TBH operate as below:T5<69. the TBH is on,
T5
as the normal logic.
2. When EVU signal is off, and SG signal is on, the unit operate
normally.
3. When EVU signal is off, SG signal is off, the DHW mode is off, and
the TBH is invalid, disinfect function is invalid. The max running time for
cooling/heating is "SG RUNNIN TIME", then unit will be off.
