AssemblyMicrocontroller board that sequences ignition, modulates feed and fan speeds, and shuts down on fault. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
Control System parts and their functions
8 top-level parts · 10 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Bare PCB | 1× | Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it. |
| 2 | Microcontroller | 1× | Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware. |
| 3 | SMD Passive (R/C/L) | 1× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
| 4 | Relay | 3× | Igniter, auger, blowers |
| 5 | Exhaust Thermocouple | 1× | Type-K probe in the flue stream that confirms ignition and detects flame-out. |
| 6 | Vacuum Switch | 1× | Pressure switch that proves negative firebox pressure and cuts the auger if the flue blocks or the door opens. |
| 7 | Room Thermostat | 1× | Ambient sensor that lets the controller modulate output between heat levels or cycle to standby. |
| 8 | LCD Panel | 1× | Status display |
