OVERVIEW HEATING INSTALLATION
A heating installation usually consists of radiators or convectors, a boiler, circulation pump and a collector with valves for
every radiator group.
Every room is equipped with a temperature sensor VMB1TS which is controlled by one or multiple temperature controllers
VMB1TC. The sensors in turn steer the relay modules VMB4RY (or VMB1RY) that control the valves. As soon as one of
the valves is opened, a relay channel can activate the circulation pump and when one of the sensors is in day or comfort
mode, a relay channel can put the boiler in day mode. When convectors with built-in fan are used, a relay channel can
steer this fan in case the room temperature deviates too much from the desired temperature, e.g. to speed up heating in
the morning.
