Use comfort schedule constraints: set different comfort ranges for different times

Comfort schedule constraints let you define time-based min/max limits (for example night vs morning vs workday). MPC uses these limits directly in optimization.

What does this setting do?

When enabled, the system uses the active min/max limits from the comfort schedule instead of simple day/night fields.

Time-based limits: set different min/max for different parts of the day.
Per day type: define separate schedules for weekdays and weekends (or other day types).
More flexible than day/night: more than two blocks, with exact times.

Difference vs day/night comfort fields

You have two ways to define comfort. Choose one and keep it consistent to avoid confusion.

When OFF: MPC uses the simple day/night min/max fields in the configuration tab.
When ON: MPC uses min/max from the comfort schedule time blocks.
Most common issue: missing blocks (gaps) or invalid min/max (min > max) in the schedule.

How to set comfort ranges for different times

Enable the setting Turn on ?Use comfort schedule constraints? in MPC settings.
Open the Comfort schedule tab Create schedules for day types (e.g. weekday/weekend).
Add time blocks For each block set start/end time and min/max limits.
Save the schedule Comfort schedule is saved separately — make sure it is persisted.
Validate with Preview Run MPC preview and verify limits are respected across blocks.

Examples (typical schedules)

Weekdays: sleep / work / evening

Example where daytime is slightly cooler and evenings are more comfortable.

22:30–06:30 min 20.0°C, max 22.0°C (night)
06:30–08:30 min 21.0°C, max 23.0°C (morning)
08:30–16:30 min 19.5°C, max 22.0°C (workday)
16:30–22:30 min 21.0°C, max 23.0°C (evening)

Weekend: longer comfort window

On weekends you may want higher minimum limits during the day.

23:00–08:00 min 20.0°C, max 22.0°C
08:00–23:00 min 21.0°C, max 23.0°C

Tips (to make MPC work well)

Make sure the full day is covered — avoid gaps between blocks.
Keep limits realistic; too tight min/max can make optimization infeasible.
For savings: lower night minimum and allow a slightly wider maximum during the day.
If control toggles too often: widen limits or adjust min ON/min OFF settings.

FAQ

Why are day/night fields ignored when the setting is enabled?

When enabled, MPC uses the time-block limits from the comfort schedule. Day/night fields may still be visible but are not the primary constraints.

What if there is a gap in the schedule?

If some time has no defined limits, MPC may not have clear constraints. Add blocks so the full day is covered.

Once comfort schedule is set, go back to the MPC guide and continue with identification and preview.
