Peter,

Thanks for the info.  Worthington has them on their web page at $118.95
which seems like a good price.

I've tried to research on the HAI page, but all they have is the
"operations" manual.  They offer installation manual only to "dealers". 
Harrummph!

Mind my asking a few (ok, a lot) questions?

How was the installation?  

Did you have to run extra wires to thermostat location or just use the 4
wires already available?  

Is there a "control box" that mounts at the HVAC unit and requires
power?

Do you have all 3 connected to one serial port or use separate serial
ports (does ECS support the "networking" of all 3 together directly?)?

My "guess" is the RC-80 can connect using the existing 4 wires from the
current thermostat, but at the HVAC unit, you have to disconnect them
and wire instead to a controller box.  Wiring from controller box goes
to HVAC unit and separate wiring (2,3 or 4 wires?) go to rs-232 of ECS. 
Is this correct?  

Thanks for your help.

Bill Walters
