Temperature Modes — Ambient vs Floor

Mysa for In-Floor Heating offers two temperature control modes: Ambient and Floor. You can switch between modes anytime in the app settings.

Ambient Mode

Ambient mode uses the thermostat's built-in sensor to maintain your desired room temperature.

| Setting | Value |

| Temperature range | 5–30°C (41–86°F) |

| Display shows | Room temperature |

| Best for | Rooms where comfort is the priority |

Floor Mode

Floor mode uses the external floor sensor to maintain your desired floor surface temperature.

| Setting | Value |

| Temperature range | Up to 40°C (104°F) |

| Display shows | Floor temperature |

| Best for | Protecting sensitive flooring, bathrooms, tile floors |

Tip Use Floor mode with Smart Limit Protection to prevent heat damage to hardwood, laminate, or luxury vinyl flooring.

How to Switch Modes

  1. Open the Mysa app
  2. Tap the In-Floor thermostat
  3. Tap Settings
  4. Select Temperature Mode
