HVAC · Sequim, Washington
HVAC in Sequim handover should explain how to clean the supplied touchscreen without unintentionally changing its operation. A screen-cleaning mode can temporarily suspend touch input; it is different from a security lock, calibration or factory reset.
Ask the installer to demonstrate the feature and identify the care instructions for the actual control. Do not assume a cleaner suitable for another household screen is approved for this thermostat.

Heating and cooling
Have the provider show how the actual control enters and leaves its cleaning state and what indicates that ordinary touch input has resumed. Keep the permitted cloth and cleaning method with the household operating guidance. If the display does not respond normally afterward, use the service contact rather than changing calibration or installation settings to troubleshoot it.
Record the model and ask which care instructions and cleaning feature apply to it.
Have the installer show the temporary input suspension and normal return without altering operating or commissioning settings.
Retain the relevant instructions and service contact; ask about unresponsive touch behavior before attempting a reset.
