bctl
1-wire based boiler/DHW/distribution heating system controller
bctl is a C++ state-machine based boiler controller utilizing a 1-Wire bus for sensors and I/O. It implements a multi-loop circulation/distribution controller targeting a dual boiler system for combined wood/fuel based heating. The wood fired boiler system utilizes hot water thermal storage and indirect heating of domestic hot water during firing. It includes provision for dumping excess heat to the distribution system, as well as provision for heat recovery during a cool-down cycle...
