Aprilaire 8820 Won't pair with C4

[iHomeHarmony]

Hey guys a little help.  I have a job site where they have qty 4 Aprilaire 8820 wireless thermostats installed.  C4 has a certified driver for this, I can't these to pair with C4 for the life of me.

 

I set the thermostat to Automation Mode

Logged into the thermostat directly and added it to wifi. I see it on the network.

C4's instructions are to just enter the IP address in composer and refresh navigators.  But it just says offline.

I talked to Aprilaire and they were at a loss.  They said the blink wifi symbol and the fact that it was on scannable on the network means it's not connected to the automation system.

The automation system, in this case C4, says to enter IP address and refresh navigators.  I called C4 and they said it might be network issue.

So I unplugged my network, plugged the EA5 directly to the Comcast router and added the thermostat to the Comcast Wifi. Disabled firewall completely. 

Still can't get it pair with EA5.  Says that the thermostat is offline.

Any help would be much appreciated!

If you turn on debug print in the driver's properties and then address the thermostats in connections, what is the output of the driver?

I just went through this with an 8830, so it should be identical. 

I can't remember exactly what I did, but I believe I ended up switching it back to AprilAire Cloud control, adding it to the network in that way from a factory reset stat. I then added thee IP address in controller for the driver, and then switched back to automation mode in the stat. I think ended up doing the trick and prevented the Wifi status symbol from flashing (not the pulsing/growing they talk about in the manual).

Thanks TMJ4, this didn't work.  Any other suggestions?
