System version 1:
Modulating weather-compensated heating
controller with EMS BUS control
One benefit of this system version is the ability of the
modules to communicate to enable heating circuits to be
regulated (WM10 and MM10 function modules) with the
MCM10 module via a common BUS, parallel to
connection J on the MCM10 module (Æ fig. 3, page 59).
This ensures optimum matching of the generated amount
of heat to the actual heat demand of all heating circuits in
the heating system. With this version, the heating system
achieves optimum comfort with maximum energy savings.
