README.mdSaunaControlUnit
Control unit for sauna oven. Ensures comfort and safety. Cheap control units are good for regualation and some basic safetey functions. This project is designed to add some comfort and safety topics
- Enhanced safety by control internal power lines and oven function
- Enhanced comfort: Acceess via WLAN
- Two relay banks to ensure the system in case of one relay fails

Questions
How big is the KTYSimulator PCB?
It measures 40.6 × 36.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KTYSimulator use?
21 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the KTYSimulator KiCad files?
From the JuergenMH/SaunaControlUnit repository on GitHub, at the commit this page was made from: the board is KTYSimulator/KTYSimulator.kicad_pcb and its schematic KTYSimulator/KTYSimulator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KTYSimulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask JuergenMH before reusing the design.
