System description:
The hydraulic system consists of the boiler circuit, the distributor, and a combination buffer that is switched as load
compensator (VAR 1) in the bypass. The return flow boost is executed via a thermal valve 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). One heating circuit is equipped with an analogue room control unit (option), the second heating
circuit is equipped with a digital room control unit (option) for remote control.
