1) Safety limit (manual reset high limit, STB)
Maximum permitted supply temperature = manual reset high limit (STB) – 32 °F
Example: manual reset high limit (STB) = 212 °F, maximum possible supply temperature = 212 - 32 = 180 °F
The safety limit must comply with the requirements applicable in your country.
