System description:
The hydraulic system consists of the boiler circuit (without main pump), and a distributor that is under
pressure. The return flow boost is executed via a bypass pump (4) in fixed speed execution, which is
activated via speed-regulation. Speed level switching must be set to the highest speed. 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.
