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 VMB1TSW which is controlled by one or
multiple temperature controllers VMB1TC / VMB1TCW(W). The sensors in turn steer the relay modules VMB4RYNO /
VMB4RYLD (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.
