I ve installed 2 of the t6 pro and both stats will not shut off when 70° is reached but they both work properly if set at 68 or 72. We just installed the system Tuesday

Typically a tstat does not turn on and off at 70 all the time. It won't turn on until 69 and will turn off at 71. If it kept the house at exactly 70 it would cycle on and off 300 times a day. Give it some time and possibly watch what it does at 68 a few more times to see if your statements are true. Im doubting both tstats are bad and don't believe you have a set up issue.

Focus pro deadband temperature settings. Can I set in auto different temperature 10pm- 6am heating 72 cooling 75 6am-10pm heating 71 cooling 74

The deadband setpoint is the limit of how close your heating temp can be to your cooling temp. I believe you are trying to program your tstat to run at certain times. This would be possible if your tstat is programmable. Not sure if yours is. But a 3 degree deadband is a good setting. Hope I answered your question!!

In the cooling mode for zone 1, why won't the temperature stay as set on the cool setting?

If it 2 degree cooler then that's fine .adjust your thermostat 2 degrees higher so you will get the temperature

I have a Honeywell VisionPRO TH8000 series thermostat which is about 2 years old and what I find is happening is when I arrive home and I find that that the thermostat has gone into revovery mode which...

Check your drain line for a float switch. It's possible it is tripping the tstat (as it should) if the drain is backing up. Another scenario, depending on the type of unit you have is that the air is being forced into the float switch therefore tripping the tstat. If you don't have batteries in it, try putting batteries in it for a week and see if the problem goes away. If so this would mean the tstat is losing power somehow. Either float switch or faulty wiring. Good Luck!!

In "Heat" mode, the displayed

You have something else going on. The tstat is probably sensing a remote temp. Is it hanging on the wall next to the furnace? Maybe warm air is coming from the furnace closet and fooling the tstat? Or an appliance or TV located too close to is, and heating it? If its quickly increasing the temp during unit operation only, it may be sensing air through the hole in the wall, directly being the tstat, where the wires come though to connect to the tstat. Try plugging that hole and test it. Or possibly the ceiling register that supplies air is facing the tstat, warming it by blowing hot air directly at it. If that's it, remove the grille and face it away. Not sure what else it may be. Hope this helps!

Leaking water sitting on bottom shelf of frig.In

Good day,
The problem you have is the defrost system is barely able to get the job done. This has been done for some time to improve the energy efficiency of newer machines.
You will need to remove the rear panel in the freezer compartment and totally defrost the drainage system. It takes time to allow everything to melt down and dry out. Rushing it will only cause the problem to reoccur in a short time.

To help in the future, there are 2 possibilities. Some models of your machine are making an aux heater to aid in keeping the drain from freezing up. Check with a good appliance parts house, not Sears.

The second thing you can do is replace the defrost thermostat that is mounted on the top of the cooling coil. It's a small 1" round disk with 2 wires connected to it.

The original may be 45,50,55,60 or 70 degrees. Whatever it is replace it with the next higher temperature rating. For example, if it's 50 degrees, replace with a 55 degrees ect. Helps a lot.
This replacement thermostat is not a sears or Whirlpool part. You need to buy the tstat as a G.E. product.
The part number is WR50X50, WR50X55 ect. The last 2 numbers are the temperature.

Setting changes! what is most effecient setting? Is a manual available?

Hi; Okay I have had over the last 25 years been ask the same question a thousand times. Technicly speacking so many BTUs are needed to cool or heat a space,(square feet).If You have a high heat or cooling load it will require more BTUS to reach Your normal desired temperature If You leave for work in the summer and turn up the tstat to 90

degrees. When You get home and turn down the tstat to 75 degrees Your air cond. system will run a very long time and pull more power due to the excessive load. This process can sometimes exceed the normal amperage rating ion the equipment and will incress Your power bill and shorten the life of Your equipment. So with this being said You can pay me now or pay me later. I personally think if you leave out for any length of time set Your tstat up to 80 degrees or 5 to 7 degrees slide cooling or heating this is acceptable. I wouldnt recomend a programmable tstat these devices are very complex to program or diagnose. These devices will make You some times pull Your hair out and run around the house screeming in a rage.

Freezer drain line keeps freezing over

Good day,
Whirpool machines have a very short defrost cycle, as compaired to many brands. This definitely contributes to the problem.
1. Make sure the drain fittings and drain hose to the drain pan are completely open. Not just open, but blown free of any debrise.
2. My experience with many whirlpool products, is ice built up under and back of the drain pan in the freezer compartment. It cannot be seen.
To solve this problem long term, means unplugging the machine, defrosting, and drying it out completely.
24 hours and idealy with a floor fan blowing into the compartment.
3. As well, you wil notice a small round disk clipped to the top of the evaporator. This is the defrost thermostat, and controls the temperature during defrost.
I change and bump this tstat up 5 degrees.
For example, if it's a 50 degree tstat, I replace it with a 55 degree. Or if it's 55 degrees I use a 60 degree model.
You will not be able to buy this as a Whirlpool item, but you can with a little effort, use a GE kit.

The part number for GE replacement kits are for example "WR50X55", the last 2 numbers are the temperature of that tstat, and run in 5 degree increments from 45 degrees to 60 degrees.

A sharp appliance parts house counterman should be able to help you.

P.S. The tstat in Whirlpools are often given in Celsius.
You'll have to convert that to farenheit
Patience in drying the machine is your friend here.

Message: "in recovery"

the "in recovery mode" is refering to a thing called energy recovery management its one of the features on your tstat what it does- when you are using the program on your tstat the "in recovery" starts your unit early so if the tstat is set to be 70 degrees at 8 in the morning when 8 o clock hits it will already be 70 degrees in your house you can turn this feature off if you want in the installation setup codes

Tried resetting the thermostat. Shows 70 degrees for a second. Then back to 78.5 degrees. When I use the arrow adjust to change settings the number does not change

Depends on your Tstat. The set point is different from room temp. My tsat show set point and room temp. But to answer you when you set at 72 and room temp is 75 . It will go back to room temp till you reach that temp. Rusty
