Algorithm selection
Quick decision guide
- AI Time Based: the first choice for most homes.
- External Sensor Offset Only: stable and simple fallback.
- Aggressive: faster warm-up, at the price of more overshoot.
- MPC Predictive (Beta): aims at a steady arrival rather than a fast one, at the price of more valve movement.
- MPC v2: experimental predictive controller; writes the valve directly where the TRV allows it.
- PID Controller: responsive control with auto-tuning.
- TPI Controller: simple proportional-time behaviour.
- No Calibration: the TRV regulates on its own sensor.
Decision matrix
| Need | Best mode |
|---|---|
| Easiest start | AI Time Based |
| Fastest warm-up | Aggressive |
| Steady arrival at the target | MPC Predictive |
| Strong disturbance handling | PID Controller |
| Very simple control model | TPI Controller |
Advanced note
MPC, MPC v2, PID, TPI and AI Time Based can set the valve opening directly when the device supports direct valve control and the calibration type is Direct Valve Based.
