Operating combination depending on the thermal load:
The following tables show the possible operating regimes of the AQUA
4
units at partial loads. The units are equipped with two
thermodynamic circuits and two or four compressors that combine their operations to meet the changing demands of the heating
system. For example, in heating mode, the units AQUA
4
M (2 pipe) are able to share their heating capacity with 50% heating and 50%
domestic hot water.
