CT100 vs. T2000 thermostat

Can anyone tell me the differences between the older CT100 thermostat and the newer T2000? I have the GC3, and the older CT100 works great - not sure if I would benifit any by upgrading to the newer style T2000?


we have the T2000 and remote sensors around the house.

with the new firmware it all the sensors and T2000 work together.

it takes a avg temp thru the house and runs the HVCA based on the avg temp vs the temp at just the thermostat.

see the attached T2000 and RTS linked in the screenshots below.
