Can I replace my Flash Thermoflash Digi 2 with a Nest Learning Thermostat?

Hi

I have a Flash Thermoflash Digi 2 thermostat and would like to know if I can replace it with a Nest Learning Thermostat?

I've tried the online checker, https://store.google.com/us/widget/compatibility/thermostat?hl=en-US&GoogleNest&pli=1  but that hasnt answered my question as

a) my thermostat has different wire labels

b)  I'm not certain if it is a high voltage system or not (there are references to 3V and 250V)

See photos attached.

Grateful for any help you can offer me

I'm not sure if you have access to the Heat Link system or just the regular Nests.

If you only have access to the regular Nest thermostats then no, it is not compatible.

I have never worked on a Heat Link system so I can't provide help with it.

thank you very much for your reply. Could you tell me the reason it is not compatible with a regular Nest Thermostat ? (eg is it the voltage?)

It looks like it uses line-level voltage which none of the Nest thermostats can handle

Hi there, I have an old yellow one like yours and want to up grade it to a white one as well. Have you had any luck please.

Hello Norine,

 

Thanks for reaching out. I'd love to know more about this.

 

Could you share a photo of your current thermostat's wiring? Also, you can check your system’s compatibility before purchasing a Nest thermostat with our online Compatibility Checker.
 

If there’s anything else I can help you with, please let me know.

 

Regards,

Mark
