About OpenTherm

OpenTherm is a non-manufacturer-dependent system of communication between modulating HVAC appliances and room thermostats. It consists of a communication protocol and an interface specification.

The OpenTherm communication protocol is primarily designed to control modulating heating appliances. The protocol is available to members of the OpenTherm Association only.

Membership is open to all companies and organizations which are active in the manufacture, distribution or installation of heating systems and components.
