Designed for setups with more than two boilers connected to a single chimney, the relay box enables the connection of up to four boilers. If the system requires more capacity, two relay boxes can be used together. This allows for the connection and control of up to eight boilers. Each boiler is managed individually using Exodraft EBC22/24 control units.
Relay box for EBC24 (up to 4 boilers). Use additional relay boxes for more boilers.
Controls for chimney fan systems for boilers and multi-storey buildings
