1. when EVU signal is on, the unit operate as below:
DHW mode turn on, the setting temperature will be changed to
70°C automatically, and the TBH operate as below:T5<69. the TBH
is on, T5 ≥ 70, the TBH is off. The unit operate in cooling/heating
mode as the normal logic.
2. When EVU signal is off, and SG signal is on, the unit operate nor
-
mally.
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.
