Mini-Split Temperature Changing on Its Own

Last updated: November 3, 2026

If you've noticed your mini-split's setpoint changing without you adjusting it, this is likely caused by Climate+, a feature designed to help maintain more accurate room temperatures. Climate+ is enabled by default when you first set up your Mysa for Mini-Splits. Here's what's happening and how to adjust it.

Why This Happens

Climate+ is an optional feature that automatically sends commands to your mini-split to compensate for temperature differences between where you placed Mysa and where your mini-split measures temperature.

The problem Climate+ solves:

  • Mini-splits have internal thermostats that measure temperature at the unit — often mounted high on a wall near the ceiling

  • This can differ significantly from the temperature where you actually sit

  • Many mini-splits stop heating or cooling slightly before reaching the target temperature

  • This often leaves rooms too warm or too cool

How Climate+ works:

  • Monitors the actual room temperature using Mysa's sensor

  • Compares this to your target temperature

  • If there's a difference, sends additional commands to your mini-split

  • Essentially acts as a smarter thermostat that measures temperature where it matters

How to Disable Climate+

If you prefer your mini-split to operate without Mysa adjusting the setpoint:

  1. Open the Mysa app

  2. Tap your thermostat

  3. Tap Settings (bottom right)

  4. Tap Thermostat Preferences

  5. Turn Climate+ off

When to Keep Climate+ Enabled

Climate+ works well when:

  • Your mini-split consistently stops before reaching the target temperature

  • The mini-split's wall position causes inaccurate temperature readings

  • You want tighter temperature control in the room

When to Disable Climate+

Consider turning Climate+ off if:

  • You hear frequent beeping (each beep is Mysa sending a command)

  • Your unit already maintains accurate temperatures on its own

  • You prefer the mini-split's native control behavior

  • The automatic setpoint changes are disruptive

What to Expect with Climate+ Off

With Climate+ disabled, Mysa will send commands only when you manually adjust the temperature. Your mini-split will rely on its own internal thermostat, which may result in slightly less precise room temperatures depending on your unit's placement.
