Minvector Baseboard Heat 24Volt Transformer

I have Line voltage Baseboard heat system.  There is a transformer installed already  Called a Minivestore Model 50240.  24V .15 Amp

 

It switches 240V and the diagram has two systems loaded onto the termostat with 2 wires out of the transformer to the thermostat.  There is a third ground wire in the run that is not ebeing used but is there.    I have pictures of the thermostat , wiring and Minvector if I could post all i would.

Let me see if this drop box link works

Can I use a Nest on this system?  

 

Thank you

Hi CDFields85, 

 

Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. Are you located in North America or Europe? Could you link here the photo of your current thermostat wiring configuration so we can take a closer look? You may also use our Compatibility Checker to determine if a Nest Thermostat is compatible with your heating and cooling system.

 

Keep us posted.

 

Best,

Zoe

I am aware of the compaitibility chart but there is a way to make this work I just need to find out how.  Is it another transformer etc... or can i turn the ground into a C wire since its not being used?  The ground goes back to the Main panel not the heating units.  They are high voltage baseboard connceted to the transformer that converts to low voltage as per my question and attachments

See if this link works

Hi there, 

 

Thanks for the confirmation, and I'm sorry for the delay. Your system could be compatible with our Nest Thermostat if there's a transformer that converts your high-voltage system to low-voltage. But to get a better understanding of your thermostat wiring, send us a photo of how the thermostat wires are connected to the thermostat, including their labels. It will help us get a better look to check for its compatibility with our Nest Thermostat.

 

Regards,

Zoe

The pictures I posted right above show exaclty what you are asking for

The scond pic that says , "wiring showing the ground not being used" is the the termostat with the Red and white wire connected thats it.

The next picture is the wiring diagram that is being used and that is the minivector information.  So you can see the wiring that wires coming into the transformer on the right then exiting to Thermostat on the left .  One red one white to the thermostat as noted on the diagram.  The green ground is not hooked up so pissibly I can turn that into a C wire.  What would the end near the thermostat connect to?

 

I havent seen a reply with the photos and wiring .  Thank you

Hello CDFields85, 

 

I'm sorry for the late reply and for any confusion caused.  Regarding your question about using the green wire as a C wire, typically, the C wire (also known as the common wire) provides a continuous source of power to the thermostat. It is commonly used to power Wi-Fi-enabled thermostats or provide a constant power supply to the thermostat. To use the green wire as a C wire, you would need to ensure that it is connected to the C terminal on both the transformer and the thermostat. The other end of the green wire should connect to the C terminal on the thermostat.

 

However, it's important to note that the specific wiring configuration can vary depending on your HVAC system and the compatibility of your thermostat. In this matter, I highly recommend you contact a professional HVAC technician to take a closer look at your system's compatibility with our Nest Thermostat and provide you with accurate advice based on your specific setup.

 

Thanks,

Zoe
