Notice :
- This hydraulic schematic just shows the
basic principle. The installation must be
in accordance with local regulations.
- With underfloor heating an over
temperature thermostat has to be installed.
- Anti thermal siphon dip has to be installed.
- up to five boilers can be linked together to
provide sequence control
