Basic module with weather-sensitive control system,
one buffer as long-term buffer
and a fresh-water module as long-term buffer
System description:
The hydraulic system consists of boiler circuit and a buffer switched as long-term buffer (VAR 2). The return flow
boost is executed via a motor valve (5) on at least 50 °C. The basic module for 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.
