Heatlink Design

As you can see from the heatlink. There are terminals for common, NO(normally open) and NC(Normally Close). These are used in the S plan wiring systems to control a zone. In addition to these terminals you can also see the OT1 and OT2 terminals, which are used for OpenTherm. As the Heatlink E can work with with a 2 wire system, it is powered by a battery to activate the relay use to control the heating system. So in simple terms means, you do not need to give power to the heatlink.
