The APU EGT Red limit corresponds to which temperature?

Explanation:
The key idea is understanding what an APU EGT red limit represents: the maximum exhaust gas temperature allowed to protect the APU from overheating. For this aircraft, that upper boundary is 807 degrees Celsius. Reaching or exceeding this value triggers protection to prevent damage, so 807 C is the official red-line limit. The other temperatures aren’t the configured limit: 806 C is not the stated red limit, 1038 C would be well beyond the safe envelope for the APU, and 0 C isn’t a meaningful exhaust-temperature limit for this context.
