At this point, there is really no way to sense or control humidity with the ELK is there?
That RCS TR-40 looks sweet. Can it plug directly into the RS-485 bus, or do you still need another serial port expander set to RS-485 mode? That would actually be a cheaper option than the others if you didn't need another serial port expander.
The only thing that sucks about it, I didn't see that it sensed humidity or did humidifier control. I have yet to understand WHY companies make high end thermostats without humidifier control. It annoys me to no end. I had a Robert Shaw at my old house that controlled the humidity, and while it didn't communicate, it was still awesome. Plus, it had an external temp sensor and it would lower the humidity level automatically to avoid condensation on the windows to keep your window sills from rotting.

It appears that you will need a serial expander to connect TR-16/40 to the M1 panel.
You will also need to consider how the TR will connect to HVAC zone controller (if that's how you want to run it). TR-16 I think povides dry contacts out for heating, cooling, fan etc, so I would suggest that you check with Daikin/Fujitsu/etc to see if they can advise where the dry contacts can connect to their controllers.
