How can I get the most out of my new Infinity Heat pumps

[derdeutscha]

We just had Infinity 19 SEER/9HSPF heat pumps installed in our house with the infinity controls. We have two systems in our house splitting the house in half with one door seperating the two halves.(3500sqft)

I understand the 25HNA936A003 has a dual stage compressor (copeland digital scroll) that runs at 21,600 btuh on low speed and 36,000 on regular speed. We previously had a 9.5 SEER AC and rarely used it because it would spike our energy bills. (We kept the temperature at about 84 degrees)

What is the most efficient way to run our new ACs? Should we keep both systems on during the day so that one system isn't overworked? We would like to keep the temperature around 80-83 degrees. If we had done that on the old systems it would have cost us probably close to $400/month (entire utility bill)

Also how much energy does just running the dehumidifier take and how do we know if the AC is running on low speed or high speed?

Sorry for all the questions.

What are you electric bills per month?
Location ?
Electric rate?
Age of residence?

Set @ 83'F: ...
basically all one is accomplishing is dehumidification.

Set the Infinity controller to 80* cooling day time and 69* heating and then set to temperature you want when your at home.

Example

Wake~ 78 cool 69 heat
Leave~ 80 cool 69 heat
Return~76 cool 69 heat
Sleep~ 78 cool 69 heat

With the old ACs using them (only one at a time) only for about 4 hours a day our bills ran $270/month. We pay 11cents/kw in florida our house was built by my dad in 1989.

That was 4 hours combined, 3 on 1 system 1 hour on the other.

Does anyone know how you run the dehumidifier without cooling (when the temperature is fine) Does dehumidification without cooling cost near as much as regular cooling?

Electric bills per month means
_______ 2006 ___ 2005 ___ 2004 ___
Jan
Febr
March
April
May
June
July
Aug
Sept
Oct
Nov
Dec

A/C is normally about 1/2 of the total electric bill.

set your humidity level around 45%, the drier the air, the easier to stay comfortable at your target temp. Tell the tech to show you how to get into the controller, tell him you paid enough for the systems and you want to know everything about them.

[emcoasthvacr]

Man -- 80 to 83 target temp.

In Florida, most of our energy is consumed reducing the high latent heating loads from the high humidity levels.

Just remember the lower your humidity level you set with your controls, the more energy you'll use reducing the latent heating loads.

Setting the indoor temperature 10 degrees below ambient while reducing the indoor humidity level 10% below ambient, might be an energy efficient solution -- you certaintly should feel more comfortable.

[aircooled53]

So, run the air conditioning at 83* so indoor humidity level and latent level is higher will decrease the amount of power used per monthly operation..What school of heating and air conditioning did you come out of?

Air Conditioning: The removal of latent heat and humidity of CONDITION space with air changes per hour.

So, I guess if the unit is set higher and humidity builds up during the day along with higher latent heat as the attic and inside of the home builds up , then at 4:45 pm you set the temperature to remove that heat it will take the system about 3-5 hours of air changes to remove that heat.

GOOD LUCK !
