Ecobee4 & Aprilaire 600 w/ External Temp Sensor

I have an externally powered Aprilaire 600 connected to my Trane XR80 furnace with the Aprilaire humidistat, but I want to connect it to my ecobee4 thermostat. Since itís externally powered, I understand I need to use the 2-wire setup, which is fine since I have an 8-wire conductor run to the thermostat. The problem is the external temp sensor.

As far as I can tell, you canít use the ecobee4 with an external temp sensor on the Aprilaire 600. Your only option to automatically control humidity levels with outside temp is to use the ecobeeís Window setting in the installation settings. Is this correct?

Iíve seen a lot of complaints about this setting not working well on the ecobee3. Does anyone know if itís any better on the ecobee4?

Yes..... that is correct.

I don't think that program has changed on the E4 over the E3.
