Peter,

Just so I understand:

1. Stand Alone (not connected to HA system)

    RC-80 <---- 4 wires ---->  HVAC unit 



2. If it is to be used with to ECS:

       +------------- 4 wires to HVAC System
     RC-80
       +------------- 4 wires to ECS system


Which means 8 wires to each thermostat (4 to HVAC, 4 to ECS) for using
with ECS.  And, each must be on its OWN serial port.


Is this correct?
