Notes:
1.
V6R series outdoor units are compatible with the 2nd generation DC VRF indoor unit and 2nd generation AC VRF indoor units (which will be released
soon).
2.
When HT hydro module units are installed together with VRF indoor units, the total capacity of HT hydro module units must not exceed 100% of the total
capacity of the outdoor units and the combination ratio must not exceed 200%.
3.
When AHUs are installed together with VRF indoor units, the total capacity of AHUs must not exceed 50% of the total capacity of the outdoor units and the
combination ratio must not exceed 100%.
4.
When fresh air processing units are installed together with VRF indoor units, the total capacity of the fresh air processing units must not exceed 30% of the
total capacity of the outdoor units and the combination ratio must not exceed 100%.
Combination ratio =
