Understanding Auto (Heat & Cool) ModeUpdated 13 hours ago
Auto Mode allows your Mysa to automatically switch between heating and cooling to maintain comfort within a user-defined temperature range. When enabled, Auto Mode provides dual setpoints—a Heat To and Cool To temperature—and Mysa will manage heating or cooling as needed to keep your space between those two temperatures.
Availability
Auto Mode is available on Mysa for Central HVAC after:
The thermostat is paired, and
The firmware is version 4.4.11 or higher.
Note: Auto Mode must be enabled in the app before it will appear on the thermostat hardware.
The app will prompt you to enable Auto Mode and set the deadband the first time you select it.
How to Turn On Auto Mode
In the Mysa App:
Tap the device tile.
Open the Mode menu.
Select Auto.
If this is your first time enabling Auto Mode, the app will:
Prompt you to enable it.
Guide you through setting the deadband (minimum separation between Heat To and Cool To setpoints).
Once enabled, Auto Mode becomes selectable on both the app and the thermostat.
To Adjust Auto Mode Settings Later:
Go to Device Settings > Thermostat Preferences in the app.
From here, you can:
Enable/disable Auto Mode.
Adjust the deadband range.
How Auto Mode Works
When Auto Mode is active, the app displays dual setpoints:
Heat To — Mysa runs heating if the room temperature falls below this setpoint.
Cool To — Mysa runs cooling if the room temperature rises above this setpoint.
Deadband — If the room temperature is between the two setpoints, the system will remain idle (fan may still run based on your fan settings).
Heat or cool engagement may still be subject to system delays and protections such as Minimum Compressor Off Time or Cycles Per Hour.
Deadband Explained
Deadband prevents the system from switching between heating and cooling too frequently.
The minimum separation between the Heat To and Cool To setpoints is enforced by the app.
Default Deadband: 4°F (2°C)
Adjustable Range:
4°F to 10°F (1°F increments)
2°C to 6°C (0.5°C increments)
Defaults, Ranges & Limits
| Setting | Value |
|---|---|
| Default Deadband | 4°F (2°C) |
| Deadband Range | 4–10°F (2–6°C) |
| Heat To Range | 41–86°F (5–30°C) |
| Cool To Range | 61–98°F (16–37°C) |
App vs Thermostat Hardware Behavior
In the Mysa App:
Full dual setpoint control (Heat To / Cool To).
Deadband can be configured under Thermostat Preferences.
Device tile and control screen show Auto Mode when active.
On the Thermostat Hardware:
Auto Mode only appears after being enabled in the app.
When selected:
The mode menu displays Auto mode icon + “AUTO”.
The thermostat screen shows AUTO (no numeric setpoints).
Users cannot adjust Heat To / Cool To directly on the hardware.
Switching to another mode on the hardware then back to Auto will retain the previously defined setpoints from the app.
Scheduling & Shortcuts
Auto Mode supports both schedules and shortcuts in the Mysa app:
You can include Auto Mode in your schedule like any other mode.
Set Heat To and Cool To temperatures for each scheduled or shortcut event.
If you experience unexpected heating or cooling behavior in Auto Mode, verify your setpoints, deadband setting, and ensure all system protections (like compressor delay) are accounted for.
