Ryan,
 
It's been a few months since my questions. I finally got this system installed - ECM4Z with 3/4 HP motor on my Bosch IDS system.
I have to say, it works waaay too good. Exceeded expectations.
 
I have 3 zones, 1 of which is considerably smaller than the others. and this setup does SO well controlling that. 
No need for a bypass, register noise is gone, and it ramps up and down so accurately based on duct temp and ESP. 
The outdoor unit responds appropriately - small zone runs, outdoor is at its lowest capacity.
Thanks for your responses and patience with my previous questions

Hi Ryan,

Controller arrived on Friday and was installed on Saturday. Works great. I actually have used it operating in a differential  pressure mode with a flow probe prior to the filter on the return and a flow probe about 2/3 of the way down the main duct (as I was taught for VAV systems).

I’m very pleased with how this works and it has solved the control problem I was dealing with. The Bosch airhandler in the installation is capable of two speeds, but of course the ECM 4Z doesn’t care about those. One possible improvement for your controller is to allow for a different HI set point for Stage 1 and Stage 2 call. Stage 2 could be at a higher TESP, which would be a bit noisier, but generally wouldn’t be used. As is stands the ramping up of the fan is gentle and not very noticeable unless you listen for it. Much better than before.

Cheers,

Ravi

The unit I installed the FAC-120 on is working great, it has gotten the temps closer to each other and has brought the humidity down to 52-57% before I was lucky to see 59%, so far I’m very impressed with this product
