Setup Nest Thermostat two-stage for Electric Wall Heaters

[cabinguy]

I have a seasonal cabin that currently has two 240 volt wall heaters.  each is on a separate circuit and I am working on a design with Aube relays that allow connection to 24volt thermostat systems like Nest.  I would like to use the heaters as a two stage system.  I have questions on the C Wire and Rh wire connections when a relay is used for each wall heater.

Please see the link below for details.

Hi @cabinguy! 

Thanks for reaching out to the community. Thank you for your interest in setting up the Nest thermostat two-stage for electric wall heaters, but no need to worry; help is here. I need to know a few things about your thermostat in order to provide you with a better resolution.

• What Nest thermostat model do you have? For your reference, you can check out this article on how to tell which Nest thermostat you have.
• When was the thermostat installed?
• What is the make and model of your HVAC equipment?
• How many wires are there?

I'll be waiting for your response; any additional details you can provide will be helpful.

Best regards,
Jeremy.
