Uneven Heat After Creating a Zone

Zones work best when every thermostat heats the same physical space (one room or an open-concept area). Grouping thermostats in separate rooms often feels uneven, even when the zone setpoint is identical.

Why this happens

• Each room has different heat loss (windows, insulation, floor level).

• The zone sends the same setpoint, not a separate target for each room.

• One heater may run longer or reach the setpoint sooner than another.

What to do

1. Keep only the heaters that serve the same space in the zone.

2. Put other rooms on their own thermostats or their own zone.

3. Change setpoint and schedule from the zone so every included thermostat stays in sync.

4. If the rooms should stay independent, delete the zone so each thermostat uses its own schedule.

This is a room-layout limit of zones, not a pairing failure.
