What E05, PRS, IF or HF means on Raypak, Pentair, Hayward & Jandy gas heaters.
What it is for
A focused workflow instead of a generic form
Pool Heater Error Codes is designed for pool service technicians looking up gas-heater display codes by brand and model family. Its public description is intentionally limited to functions present in the Android app.
Check the entered values, calculated output, saved record, and any source or assumption notes before relying on the result.
Core field and project records stay on the device. They leave when you deliberately use an available export or Android share destination.
Verify before field use
Always verify the exact model and code in the current manufacturer manual. De-energize and follow qualified-service procedures before opening equipment.
