1. When EVU signal is on , and SG signal is on, as long as the DHW
mode is set to be valid, heat pump will operate DHW mode priority and
the DHW mode setting temperature will be changed to 70ºC. T5＜
69ºC, the TBH is on,T5≥70ºC，t he TBH is off.
2. When EVU signal is on , and SG signal is off, as long as the DHW
mode is set to be valid and the mode is on, heat pump will operate
DHW mode priority. T5＜T 5S-2，t he TBH is on,T5≥T5S+3，t he
TBH is off.
3. When EVU signal is off, and SG signal is on, the unit operates
normally.
4. When EVU signal is off, and SG signal is off, the unit operates as
below: The unit will not operate DHW mode, and the TBH is invalid,
disinfect function is invalid. The max running time for cooling/heating is
"SG RUNNING TIME", then unit will be off.
