- Thermostatic control of the heating temperature (possibility of high and low temperature)
- Motorized zone valve, on heating side
- Priority control in the production of domestic hot water (except GE556Y171)
- TMV2+TMV3+WRAS-certified anti-scalding thermostatic mixer (except GE556Y171)
- Manual air vent valve, adjustable by-pass, dynamic balancing valve, primary side (except for the by-pass, there is no primary flow when the satellite is not active)
- Pre-arrangement for housing the HIU inside a metallic template fitted with shut-off valves
- Brass spacers for installation of thermal energy meter and domestic water meter
- Box with terminal board for electric connections
- Max. working temperature: 90 °C
- Max. working pressure:
