Can I buy a Nest thermostat and will it work? I hate the thermostat that came with our loft.

Red - marked ‘12v’

Black - marked ‘gnd’

Hiya Chicl32,

 

Thanks for showing an interest in our community!

 

Unfortunately, since your current thermostat system lacks the standard labeling found on most thermostats, it's impossible to definitively say whether a Nest thermostat will be compatible based solely on the wire colors. 

 

Each wire on your thermostat system has a specific function, such as providing power, triggering heating or cooling, or controlling the fan, and Nest thermostats require specific wires to be present for proper operation.

 

Given the absence of standard labeling on your system, contacting a qualified HVAC technician is the best course of action. They can visit your location, identify the function of each wire in your current thermostat system, and definitively determine Nest thermostat compatibility.

 

Let me know how it goes.

 

Regards,

Angel.
