- Worth noticing
- The site distinguishes manufacturer-manual statements from owner reports and says it does not bench-test heaters.
Field notes
Readers first match their heater to a controller description, using details such as button layout, screen type, and whether codes include a dash. The reference covers multiple error formats, including rotary-knob LED flashes, and offers separate symptom guides for problems such as white smoke and lockouts. Its stated method relies on manufacturer and seller manuals plus public owner reports, not bench testing.
