System description:
The hydr. system consists of the boiler circuit, the buffer switched as long-term buffer (VAR 2), and the distributor. The
return flow boost is executed via a thermal valve (28) on at least 50 °C. The basic module for boiler / DHWC & buffer
control is equipped with a weather-sensitive control system for 2 heating circuits (option), and is combined with a bus-
capable heating circuit expansion module (25). Two heating circuits are equipped with analogue room control units
(option), the two other heating circuits are equipped with digital room control units (option) for remote control.
