Auxiliary Coil

This innovative system gives the possibility to use the fancoil of the FNL series with one single coil in a 4 pipe system.
By this way the main coil with 4 rows can receive water from the system at a lower temperature than usual, and get an equivalent or even higher capacity.
For instance the feeding water temperature can be 45°C instead of the usual 70-60°C with a relevant energy saving. The system ACHPS, with its combination of special valves and thermostat, provides also the by-pass of the water in the fancoil maintaining a constant pressure in the system.
