Honeywell Thermostat Programing

Canz · May 15, 2014

Hello, I am hoping someone can help me out and give me some ideas. I am using the Z-wave Honeywell thermostat (TH8320ZW) and I have turned the internal Home/Away programing off.

I have created some programs to set the cool and heat temp set points such as.

*******

If

M-F and time is 5:30am

Then

Stop program â€“ Bedtime

Set â€“ Heat Set point to 69

Set â€“ Cool Set point to 74

Else

Blank

********

I have additional programs set up that take effect at different times though out the day and then end the program that ran before it.

But what I am looking to create is a program, that when someone changes the temperature at the thermostat it will suspend all of the other programs and Hold the new temperature setting for a period of time (2hours) and then picks backup where it left off. Does anyone have any ideas on how to create something like this? Or something that will monitor set point change.

Thanks

Matt

Hi Matt-

Place all of your tstat schedule programs in a folder.

Create the following program outside of that folder:

Program: StatWatcher

If
       (
            On Mon, Tue, Wed, Thu, Fri
            From     5:25:00AM
            To       7:59:59AM (same day)
        And (
                 Status  'Thermostats / LR Thermostat - Main' is not 69Â° (Heat Setpoint)
              Or Status  'Thermostats / LR Thermostat - Main' is not 74Â° (Cool Setpoint)
            )
       )
    Or (
            On Mon, Tue, Wed, Thu, Fri
            From     8:00:00AM
            To      10:59:59AM (same day)
        And (
                 Status  'Thermostats / LR Thermostat - Main' is not 70Â° (Heat Setpoint)
              Or Status  'Thermostats / LR Thermostat - Main' is not 72Â° (Cool Setpoint)
            )
       )

Then
       Wait 2 Hours
       Run Program StatWatcher (Else Path)

Else

Then set the folder conditions for thefolder with the schedule programs to:

Folder Conditions for 'Testing'
Add conditions to limit when programs in this folder are allowed to run.

If
       Program 'StatWatcher' is False

Then
  Allow the programs in this folder to run.

Obviously, you will need to duplicate the schedule and values for Heat and Cool set points in the StatWatcher If section. Be careful to get the Or's and And's in the right places. I only did 2 time frames as an example, you will need to continue with the remainder of yours and adjust the times accordingly.

Also, my stat is Venstar/Insteon - the set points are represented on the "Main" node. Your Zwave stat may represent these differently. Adjust the code accordingly.

This will prevent scheduled changes from occurring for 2 hours after a manual change is made. After 2 hours the folder will re enable and the next scheduled change after that point will happen normally. If the previous change was missed due to the hold, it will NOT take effect after the hold expires. If you wish for the changes to take place at the hold expiration time, we will need to trigger the schedule programs within the folder. To do that, we can modify the Else section of StatWatcher to include a "Run If" of each schedule program.

Hope this helps.

Xathros, Thank You for the Reply. I will give that a try tonight. But I had 3 questions

1) Can I put all of the timeframes under one StatWatcher Program?

2) I am not understanding the Else section of the Statwatcher Program. Should it blank to create the False condition under the Folder Conditions?

And to add the trigger to cause the Programs to run after the Hold would it just be

Else

Run IF â€“ Program A

Run IF â€“ Program B

And so on.

3) And just to confirm for those programs to run properly I need to use

IF Time is â€“ 5:30AM to 8:00AM

(or )

IF Time is â€“ 5:30AM

Thanks for all your help, Matt

Xathros, Thank You for the Reply. I will give that a try tonight. But I had 3 questions
1) Can I put all of the timeframes under one StatWatcher Program?

Certainly. I only did 2 timeframes in my example but you can continue what I started adding more to the if in the same structure that I provided.

2) I am not understanding the Else section of the Statwatcher Program. Should it blank to create the False condition under the Folder Conditions?

If left blank, it would have the limitation of having to wait till the next schedule arrived for the automatic changes to occur again. The folder will become enabled as soon as the 2 hr delay expires but that won't trigger the schedule programs rather will simply allow them to be triggered. The next trigger would be the first schedule time that occurs AFTER the delay has expired. If you ad Run If's of the schedule programs to the Else of StatWatcher, we can eliminate that delay.

And to add the trigger to cause the Programs to run after the Hold would it just be

Else

Run IF â€“ Program A

Run IF â€“ Program B

And so on.

Exactly. Where Program A, B, C... are your schedule programs withing the folder.

3) And just to confirm for those programs to run properly I need to use
IF Time is â€“ 5:30AM to 8:00AM

(or )

IF Time is â€“ 5:30AM

Your existing schedule programs can use either format. For the watcher, ther need to be in the From...To range format.

Thanks for all your help, Matt

Anytime. Happy to help.

Xathros, I am hoping you can help me. I have tried your suggestion with my program however i am running into a problem. It was working fine but for some reason it has stopped working correctly on its own. Normally i get it working where the stat watcher is false and then the corresponding daily program starts. from what i can tell the daily program runs until it gets to the daytime shift. 6:30 - 16:30 and then it should lower the temp for when I arrive home from work. However it seams that at 16:30 it doesn't low the temp and the StatWatcher program kicks in and keeps the temp at the previous set temp of 80deg and doesn't resolve until i run the Else path of the StatWatcher.

This is the programs, first is the StatWatcher followed by daily programs. Please let me know if you notice anything that could be causing my problem.

Thanks again- Matt

@Canz

So sorry for the delay in getting back to you. I was away on Vacation and have spent the last 3 days catching up here.

On first glance, my suspicion is that your problem occurs on Wednesdays. This could be due to the fact that Weds is missing from the Spring_Weekday_1630-Sunset program. I also notice Weds missing from Spring_Weekday_0530-630. If this is by design, I will dig deeper but on first glance this appears to be the issue.

That's cool, no rush. Sorry i am just now getting back to you, Wednesday was left out by design because my wife was working from home, but i am having the problems on the other days too.

oberkc · August 23, 2014

Is it possible you have a couple of "loops" here, where executing the THEN or ELSE section of your first program causes a change in the conditions, causing a reevaluation, causing....etc...? It appears to me that your first program condition is based, in part, on the setting of your main thermostat. It further appears to me that each of your "WEEKDAY" programs causes a change to you thermostat setting which would cause a reevaluation of your first program conditions.

I am also a little confused about what it is you are trying to accomplish, suspecting that there is a lot of unecessary complications here. If all you are trying to do is to set the thermostat to certain settings at certain times of certain days, why not use a handful of simple programs, such as:

IF

On Mon, Tue, Thu, Fri

And time is 4:30:00PM

Then

Set 'Main Thermostat' 75° F (Cool Setpoint)

Set 'Main Thermostat' 64° F (Heat Setpoint)

Else

- No Actions - (To add one, press 'Action')

If

On Mon, Tue, Thu, Fri

And time is 5:30:00AM

Then

Set 'Main Thermostat' 76° F (Cool Setpoint)

Set 'Main Thermostat' 67° F (Heat Setpoint)

Else

- No Actions - (To add one, press 'Action')

If

On Mon, Tue, Wed, Thu, Fri

and time is 6:30:00AM

Then

Set 'Main Thermostat' 80° F (Cool Setpoint)

Set 'Main Thermostat' 55° F (Heat Setpoint)

Else

- No Actions - (To add one, press 'Action')

If

On Mon, Tue, Wed, Thu, Fri

and time is Sunset

Then

Set 'Main Thermostat' 77° F (Cool Setpoint)

Set 'Main Thermostat' 65° F (Heat Setpoint)

Else
