Are you confused about the electronic control system of the heat pump? Maybe this is worth your try. Not only does it have what you want, it also has more novel functions:
1. Silent/Smart/Boost operation mode optional. Matching different energy saving demands.
2. Timing operation between silent and smart mode. No extra care is required.
3. Beautiful screen, much more user-friendly. Etc.
If there are any other functions of interest, welcome to share together.
