Nest Thermostat compatibility

[Doccolo]

I want to buy a smart thermostat but the wires of my current one don't even appear in the Nest compatibility checker.

Any ideas?

I have a heating system with a boiler supplied by district heating and radiators + a couple of electrical towel rails in the bathrooms.

Hi Doccolo,

Thanks for the photos and for getting back to us.

Wire labels such as Q1, Q2, Q3, and L indicate an incompatible system.

These systems usually only work with thermostats made by the same manufacturer. But some HVAC systems may also have the option to use standard heating system wires. Contact a local pro and have them check if your system can be rewired to be Nest compatible.

Best,
Mel

Hi Doccolo,

Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.

Thanks,
Mel
