Hi Njboluc1,
Thank you for reaching out and we're sorry for the delay.
As long as the HVAC unit is 24V it could be compatible with the Nest Thermostat. You only need to connect the R and W to the R and W terminal on the Nest Thermostat and the B wire to the C terminal.
Also, check out this online compatibility checker for further information.
Best regards,
Ryan
