Satellite with double heat-exchanger

Satellite with a double exchanger, for centralized systems for high and low temperature heating and the production of sanitary hot w ater (only for GE556Y172-Y173), complete with:
- Exchanger for separating the secondary heating circuit from the primary circuit of the condominium.
- Exchanger for the instantaneous production of sanitary hot water (except GE556Y171).
- Self-regulating circulator , which conforms to directive ErP (2009/125/EC), expansion tank, safety valve, manometer, pressure switch, automatic air vent on hea ting side.
- Thermostatic control of the heating temperature (possibility of high and low temperature).
- Automated zone valve, heat ing side.
- Priority control in the production of sanitary hot water (except GE556Y171).
- TMV2+TMV3+WRAS-certified anti-scalding th ermostatic mixer (except GE556Y171).
- Adjustable, by-pass, dynamic balancing valve, primary side (except for the by-pass, there is no primary flow when the satellite is not active), automatic air vent.
- Preparation for housing the satellite inside metal template s provided with interception valves.
- Preparation for installing a thermal energy meter and a sanitary water meter (except GE556Y171), using spacer pipes (in plastic on heating side, and in brass on sanitary side).
- Box with terminal board, for electrical connec tions and commands.
- Maximum operating temperature: 90 °C.
- Maximum operating pressure: 16 bar
(10 bar with spacer pipe in plastic )
