Icomfort touch thermostat VS comfortsense 7000.


I have a 3 ton Lennox system, installed in 2005, it has the CBX32MV air handler, HPXA16 2 stage compressor unit, no humiditrol. The other day I got three great thermostats at an auction. Two are Lennox, the Y2081 comfortsense 7000 and the 49W95 Icomfort touch. When I bought my heatpump they said I could control humidity in the house, but needed an outdoor temperature sensor (X2658). At present I have the signature stat.
I think both of these Lennox thermostats may be able to do the humidity control if I had the outdoor temperature sensor, and I am sure that my airhandler can't communicate with the Icomfort stat as it is presently configured. My questions are:
1. Is there a significant advantage to the Icomfort thermostat over the comfortsense 7000? are there other efficiencies to be gained by using one or the other?
2. If there are significant gains available by using the Icomfort stat, can the airhandler be made compatible by just changing out the control board? would the control board in the compressor unit have to be changed as well?
3. Can I do dehumidification to a target value of relative humidity without the humiditrol unit? I am not concerned with being able to add moisture to the air, just remove it.
4. would I need other sensors or hardware to manage dehumidification?
I also got a honeywell vision pro 8000 model TH8321U1006, which I think is essentially the same as the comfortsense 7000.

Thank you for your time, any advice would be greatly appreciated. ag1380

The honeywell 8321 monitors the indoor humidity when programmed to do so without additional sensors. The other two t-stats Im not familiar with. Installer code 380 will activate this feature.
Warning: It controls the humidity by allowing the indoor temp to be lowered by as much as 3 deg. below set point to achieve the desired humidity level. The t-stat will automatically control the unit in first stage cooling if you have in set up for multi-stage.

Without a communicating system the comfort sense 7000 will be a better option. No need for the outdoor sensor if you just want to dehumidify. Run a wire from D on the stat to,I believe it's DS in the air handler. There's also a jumper on the air handler control board that links R and DS and it will need to be cut.

Marty S and Mr. Eubanks,

Thank you for taking the time to reply to my post. I guess I'll use the Comfortsense 7000 to keep it all in the family. Thank you for the advice on the control board and wiring, I should be able to handle that without a problem.

One more question, I would guess that the Comfortsense t'stat also lowers the set point and "overcools" to dehumidify. I can imagine it would manage both the fan speed and compressor in the process, do you know if it does it without such a potentially large temperature swing as the Honeywell may impose?

Thanks again,

Mark E

Basic setting-no over cooling. It only slows the blower speed.
Precision- will over cool by 2 degrees and slows blower speed
Don't use humiditrol or aux settings.
