I am a building contractor and recently had an A/C contractor install a high
end 18.6 SEER Lennox Heat Pump with a dual stage compressor and variable
speed air handler in one of our custom homes. We paid for, and the final
invoice clearly indicates that they were to install a Lennox thermostat with
humidity control. They actually installed a Honeywell TH8320 which does not
have idependent humidty control. I'm trying to figure out what to tell them
to replace the thermostat with.
The Lennox tech support individual told me that he thought that for true
optimal humidty control where it works by running the blower on low to
rapidly dehumidify the home, we would have to use the Lennox 81M28
thermostat and that he didn't think we could use other brands.
My question is this: do you think that that the suport tech was correct that
we have to use a Lennox branded thermostat to work best or to work at all
with the Lennox for humidity control? I'm questioning him since he didn't
sound 100% like he was positive about the advice he was giving me.
If it's true that other brands will work just fine with the Lennox system,
do you have a recommendation for the best/most reliable/most bells and
whistles/whatever brand of thermostat? Since we definitely have to swap out
the thermostat, I figured we might as well ask the question as to which is
the best one to buy for them. The Honeywell units sure look much nicer than
the Lennox thermostats (the Honeywell VisionPro TH8321U1006 has independent
dehumidification control), but I don't want to make a decision based purely
Thanks so much for any guidance you can provide me.
