Serial Thermostat for Modulated Furnace

[George M]

I am completing the construction of a new home. In it are three Rheem modulated furnaces. I wanted to be able to control them with my automation system (ELK - CQC) but cannot find any info on a thremostat that I can connect to that works with modulated furnaces with ECM motors. In reading the literature on the Aprilaire 8870, it does not mention modulation at all.

Does anyone know if there is a product that will work for me??

Thanks

It looks like you will only get stage 1 and 2 with the 8870.

Thanks for the link. However it didn't really answer the question. What I am trying to find out is are there any serial controllable thermostats that will keep the furnace and blower fully modulated.
