Note:
due to different system, maximum 3 temperature differences (DT1o, DT1F), (DT2o,
DT2F), (DT3o, DT3F) can be set, setup steps are same above steps.
8.4 TEMP Temperature main menu
For solar system, the factory set parameters are for the best operation condition, which is
fully integrated into the entire solar system. But these parameters can also be set
individually to cater the special requirements, please carefully observe the operation data
of system components after setting.
Note:
Parameters that can be set rely on the system design; it means not all the
parameters are suitable for all solar systems.
Following submenu can be accessed though TEMP main menu.
