What is it?

This Relay Box is suitable for heat pumps and other systems that have a heating contact and a cooling contact that are 0-250V and 0-16A.

When Adam has a demand, Adam’s heat source contact will close. The plug then determines whether this demand is for heating or cooling. When there is a heat demand, the heat contact of the Relay box will eventually close. When cooling, the cooling contact of the Relay box will eventually close. If there is no heat or cooling demand, both contacts are open.

Note, does your heat pump have a demand contact and a potential-free heating/cooling contact? Then only use a plug with a 230V relay box. Connect the Relay Box 230V plug to the heating/cooling contact and set it as device type cooling contact and connect Adam to the potential free demand contact.
