Parameters may contain either static numeric values or runtime placeholders.Placeholders are replaced live during program execution.
Numeric ranges
Unless otherwise specified, numeric parameters must be in the range 0–65535.
Runtime placeholders
Single-letter placeholders may be used in any parameter position (T,S,O,P,I).
| Placeholder | Meaning | Notes |
|---|---|---|
| A B C D E G | User parameters | EEPROM-backed, editable in GUI |
| X Y Z | Temporary storage | Runtime values |
| r / R | Formula result | Result of last executed formula |
Restrictions:
- Placeholders must be exactly one letter
- Lowercase sensor variables
a b c dare formula-only - Placeholders bypass static range validation
WARNING:
Runtime placeholders disable most fail-safe checks.Users must ensure correct ranges, execution order, and initialization.Invalid runtime values may cause unexpected behavior.
