Your thermostat might show up just fine after this. We suggest that you try to clear the app data (in your phone settings) if you must reinstall the app.
  • Try resetting the account at the thermostat and rebooting your phone if you’re still facing glitches.


What does re-setting the thermostat do?

In a nutshell, resetting your Daikin thermostat means you’re restoring it to the factory settings.

Overall, the action can help correct issues that could be affecting it such as programming problems, connection issues between your HVAC system and the thermostat, and more.

In truth, digital thermostats tend to need a reset from time to time to put it back into proper working order (they typically lose efficiency over time).


When should you reset a thermostat?

You can tell when resetting the thermostat is necessary because it normally stops regulating your home temperature as it has always done.

For instance, a malfunctioning thermostat might be the culprit if an A/C or furnace starts to short cycle and run almost nonstop.

A reset may also be needed after a power outage.

In addition, the remedy to some Daikin thermostat error codes is resetting the thermostat.

To come to the point, it is always worth trying to reset the thermostat anytime you’re experiencing HVAC system issues.

In fact, it should be one of the first Daikin thermostat troubleshooting steps you try when your thermostat starts to generally act funny.

But make no mistake about it- not all thermostat mishaps will be rectified by resetting the unit, not least the critical ones.

Of course, such errors are beyond DIY troubleshooting and are better left to a professional repairman.
