Our warmup floor thermostat (3iE) was installed in 2016 and has worked fine until last week when the screen went black and we noticed 3 tiny blue lights flashing at night (they are always flashing, we just didn't initially see them). What is the problem? Thank-you

If a Warmup 3iE thermostat has a black screen and flashing blue lights, it could indicate a power issue or a system fault. The thermostat may have entered standby mode if no buttons were pressed for 1 minute, causing the screen to dim, but flashing lights suggest a deeper fault. It may also require a reset by holding the power button for 3 seconds, or it could be experiencing a wiring or hardware problem that needs professional inspection.
