The Adam (HA) gateway works seamlessly with OpenTherm boilers and heat pumps as well as 24V 1A on/off contacts. This gateway is designed to optimize efficiency and control over your heating systems, regardless of the type or brand of boiler or heat pump.
In the Netherlands, almost all boilers and heat pumps support OpenTherm or On/Off 24V/1A. Some heat pumps have a 230V on/off contact. You cannot connect Adam directly to this and a Relay box 5V is required. Do you want to know for sure how to connect Adam (HA) to your boiler or heat pump? Then look at the Plugwise Connection Table.
