Idle Band — how far the temperature can drift from the target before the system activates.
Shutoff Buffer — degrees before the exact target where devices cut off. Positive = early cutoff, letting thermal momentum coast in. Negative (down to −2°C) = deliberate overshoot. Set to 0 to run all the way to target.
Momentum Factor — °C of early shutoff per °C/hr of current temperature rate. At 0.25 (default), a room cooling at 2°C/hr shuts off 0.5°C before target and coasts the rest. Higher = shuts off earlier, relies more on inertia. Auto-set from outdoor/indoor gap.
Thermal Coeff — °C of early shutoff per °C of outdoor/indoor temperature gap. At 0.05, a 10°C gap adds 0.5°C to the shutoff margin (outdoor conditions keep pushing the room after appliance stops). Higher = more aggressive early shutoff. Auto-set from outdoor humidity.
Coast Direction — Cool+: cooling cuts later (runs further toward/past target), heating cuts sooner (stops below target) — room settles lower than target. Warm+: cooling cuts earlier (stops above target), heating cuts later (runs past target) — room settles higher than target. Effect scales with Idle Band: at ±100% with a 2°C band the shift is ±0.8°C. Neutral = symmetric shutoff at the momentum-predicted point.
