Relay module with pump output

Relay module (available in 2 or 4 channels version) designed to drive loads (more precisely, electro-thermal valves or circulators) via radio in home or office heating/cooling systems. It features independent channels, each of which can be associated with an independent transmitter (radio thermostat or chronostat). This system is undoubtedly the best solution for all buildings in which wires cannot be laid between thermostats and the heating/air conditioning equipment room.
