The Green Speed does go into dehumidification mode thoughout the day, but I've been monitoring my meter readings daily and I can tell the energy usage is negligible.
I see this programming logic as a minor irritant during the "shoulder season(s)" here in Florida, which is pretty much November through February. But it's still a great improvement over my old "on" or "off" 10 SEER 3.5Ton Rheem!
For the time being, I've elected to set the control at 75* for cooling 24/7 and I have the heating set for 70* during the day, 64* from 11pm to 8am (cool sleeping is great), and 68* for "wake-up" time (8am-10am). For the last 2 weeks, it's occasionally been cold enough overnight for the heat to come on briefly at wake-up time, but the house will stay between 70* and 73* during the day so the A/C never comes on. After the occasional morning warm-up, there's no need for heat during the day either.
When it gets to 72/73* in the house, I'd still like to see it dehumidify automatically, but it won't when the last hp event was heating. When I feel the humidity is getting a little high, I actually have to go to the control and switch it from "auto" to "cool" and then back to "auto" so it will dehumidify as needed and still be ready for heat in case it gets cold overnight. It appears this will be a daily task for awhile unless Carrier updates the software sometime in the future. (Sorry, Teddy Bear, but I still have no room nor interest in a whole house dehumidifier.)
What are you setting your humidity level at? 50% is optimal. In the "winter" months, you shouldn't have much need for dehumidification.
Maybe some of the other experts can chime in who are more keen on dehumification than I.
I forgot to mention that I recently adjusted the auto cooling setpoint from 75* to 72* for "sleep" time (11pm until 8am) to allow for additional dehumidification in the overnight hours. So before I go to bed around 11:30, I also have to make sure the hp is idle in the "cooling" mode so dehumidification will happen. This hasn't been a problem so far, since the indoor temp has never gone below my "sleep" time heating setpoing of 64*.
Keep posting the results. It is a learning expirence for all. As this progreses , it will be clear what needs to be done. Fresh filtered ventilation air and <50%RH is a must.
Hope a/c designers catch on to what is possible using simple a/c with a whole house ventilating dehumdifier. When this home is unoccupied, the a/c is turned off. The dehu is set at 50%RH with fresh air off. The results are a <50%RH dry home with $15 per month electric bill.
A Ultra-Aire whole house ventilating dehu is no more than a VS a/c.
Is this data from your home in Cape Coral? Do you have pictures of the unit installed, including how it's attached to the ahu, how it vents to the outside, how it drains? From pix I've seen elsewhere, I don't see how such a unit could be installed near the ahu in my laundry room.... also wouldn't want to add another $15 a month to my electric bill.
I also don't see a need for additional ventilation in my house. Two separate infiltrometer tests have shown that my existing ventilation exceeds the ASHRAE minimum, with duct leakage at less than 5%.
So far, the Green Speed dehumidification has cost me almost nothing! I mean my kWh usage for the 2 months since installation is as low as it's EVER been... less than in ANY prior year duing months when NO A/C or heat was used (usually Dec & Feb). Total Dec electric bill averaged 18 kWh/day, Jan bill is on track for 19 kWh/day.
