Will act as a trigger only upon recipet of an "off" command. Will evaluate as FALSE when triggered. Evaluates as TRUE if program evaluation is triggered by another condition. This (finally) explains the behavior but as a developer I still feel strongly this is a bug. Logical statements should not evaluate to 'FALSE' when the evaluation succeeds. That is bug #1 however if you accept that is how UDI did this (a bit backwards from about any other system I can think of) then bug #2 is that the statement evaluates as TRUE in any case when triggered by another condition (an If Control should only evaluate to TRUE if the controlled item was activated) I realize both aren't bugs (one negates the existence of the other) but do you 3 really think this is 'intended' behavior? Yes, ISY is event driven. "If" statements are affected by any event regardless of how it came to happen (that includes its own then/else clauses). Your first program ran true, the variable changed, this triggered the program "if" again, this time it ran false and ended. This all happened in microseconds. Your second program ran true, the variable changed, this triggered the program "if" again, it ran true again (because "is not" was true and included as an "or") which kept looping back. If you just switch to an integer variable this won't happen since integer variables are never a program trigger. They do evaluate when something else triggers the "if" clause, but they don't cause the evaluation. If you need that same variable to act as a trigger somewhere else, you can have both a state variable and integer one representing the same thing and set both at the same time, but only use the integer variable in your "if" clause of this program. Note: When you name variables, include an "s" or "i" in the name for ease of differentiating. ie $sDefault_Occupancy_Time_In_Hours or $iDefault_Occupancy_Time_In_Hours

That appears in complete opposite to what LeeG stated "Press the device On paddle/button, the Programs | Summary will show the Last Run Time does not change. With If Control the command received has to match the command specified in the If for the Program to be triggered." This is because Lee was referring to a different program that only contained a "switch off" command I agree your reading *should* be how it works... Bill Just to be 100% certain I ran that program last night and it worked as expected. In other words, click "on" and the program runs true click "off" and the program runs false any other action on the switch does nothing (ramp up/down fast on/off etc). edit. . . I just read your program. The loop is from the variable. You are probably using a state variable which is triggering the program. Try an integer variable EDIT

Just be careful not to mess your equipment up. On heat mode there is a reversing valve and it usually turns heat strips on as part of a defrost cycle. You wouldn't want to mess that up and cause damage or freeze up your unit.

Lee's above program will run true when you click "on" on the icon dimmer, and false when you click the "off" side of the dimmer. It can not create a loop. The design of this program has 2 triggers (clicking "on" or clicking "off" on the referenced dimmer). No other action will cause the program to run (natively). "On" click triggers the first line. . . it is true. The second line also evaluate as true because indeed clicking on "is not" clicking off. "Off" click triggers the second line. .. it is false. The first line is also false because indeed clicking "off" is not "is" clicking on. A note: Using the terminology "clicking" instead of "control" might help you. It really drives home the point that you have to actually push the switch and make it "click". No other action besides actually pushing (clicking) the switch triggers a "control" condition.

This is just another hot water heater instead of your current tankless. No this is a point of use instant water heater. I think I could put it under my sink so there is no little under sink tank to keep warm. Would this work? Yes, it is another hot water heater. It is a smaller electric version of what you already have hanging on the outside of your house. It will work. . provided you have a 240v 60 amp circuit available under your sink.

These are what I was talking about. They only turn on when they are actually going to be used. They don't necessarily give you "instant" hot water, but they do greatly speed up the process. Especially if used with a motion detector so that they flip on prior to you actually turning the sink on.

I don't recommend this. It forces your tankless heater to cycle all the time. Every few minutes the pipe cools down and this thing turns on. Notice it says "be sure this doesn't void your warranty" because it usually does .. . for good reason. Although, you can add a small holding tank under the sink and recirc to the holding tank. The holding tank takes a lot longer to cool off so you don't get the constant cycling.

This is just another hot water heater instead of your current tankless.

No good tankless solutions. You can add a tank located closer to the other stuff and run a recirc pump between the tankless heater and the tank. You can't do recirc on tankless without adding a separate tank as this results in excess cycling of the heater. You can add a booster pump to get the water to the other side of the house faster. . . but you can't have the booster pump move too many gpm's or it will exceed the tankless capacity to heat the water. Basically the booster pump is near the point of use and it pumps water from the hot line to the cold line until it gets hot. For example, if there is 5 gallons of water in the pipes and your sink draws 2.5gpm. .. then it is 2 minutes to get water to the sink. If you add a pump that pumps 5gpm plus the sink at 2.5 gpm you drop the time down to about 45 seconds. But realize you are drawing 7.5gpm which may result in less than fully hot water. A system to turn the booster pump on at the right time is where the fun comes in. ISY can control that . . . but most people just have a button to turn it on. Once the hot water gets to the point of use the booster shuts off and doesn't turn on again until someone pushes the button. You can get fancy with other ways of turning the pump on using ISY.

I have cai webcontrol boards monitoring some stuff. I also have some of the lacrosse technology weather stations that log data. The version I have allows you to download the data and import to excel where you can do all kinds of fancy stuff with it. The latter choice is easier and cheaper, but the cai choice lets you put the data into the ISY as variable values in essentially real time.

My house was new construction. My office was a remodel which I just finished 3 weeks ago. My office had a bunch of roof vents which we mostly just boarded over. I had some of them boxed out with duct-board so the hvac guy could tap into them for fresh air and exhaust. I have one of those temp reader laser gun things. Last summer, I pointed it at a west facing roof at 6pm when it was 105 outside and sunny. The roof was 150 degrees. I went in the attic and pointed it at the same spot on the under surface and it was 87.

Of course the price point is very different here, but you might consider forgetting about venting the attic at all. Close up all the vents and spray foam the entire under side of the roof deck. This works awesome. I have both my house and office that way. If you have any hvac equipment/ducting in the attic it will work far better. Your attic will be much more temperate (mine goes from about 60 when it is 20 outside to about 85 when it is 105 outside) so you can actually use your attic for storage or have electronics operating in there. I promise you will see a sizable drop in your hvac bills. Also, no more fiberglass! Man I hate that stuff. And it seals way way better than any other technique. And when you do the roof deck you don't have to worry about leaks around all your ceiling fixtures. But back to the temp. I use a cai webcontrol unit and ioguy's program to log the temp readings every 5 minutes. It's a nice way to gather that data. You can also use some of the lacrossetechnology thermometers with a logging function and download that to a graph. Those are pretty cheap and work pretty well, I have one in my wine cellar, keg, and outside. I used it extensively to evaluate and adjust the hvac equipment in my wine room to optomize the tev settings.

Are you monitoring/logging/graphing your attic temp relative to fan status? I would be curious to see if the temp drops and by how much. Also!!!! be advised that if you do not have the attic/house interface tightly sealed, you may be sucking conditioned air out of the house with your attic fan and thus shooting yourself in the foot! You must have every crack sealed up (and that is hard to do) and you must have very adequate vents for air intake (so that the attic has minimal relative vacuum and is less inclined to suck from the house).

"Is there a way to programattically tell ISY that the Movie scene is no longer On?" Scenes do not have on/off status. But I think what you have is a program that runs in response to turning a scene on, so perhaps what you mean to say is that the program is "true". The way to make the program show "false" is to run the "else" clause. For example, 2 programs are triggered from x-10 and are mutually exclusive. Program 1 If x10 scene 1 is turned on Then set lights this way run "else" clause program 2 Program 2 If x10 scene 2 is turned on Then set lights that way run "else" clause program 1 "Is there a way to programmatically tell ISY that a program is no longer running?" Can't really figure out what you mean here. Again, I think you are confusing programs with scenes here.

It has been a hot topic many a time. Personally I would like to see a check box next to each "if" condition that could be used to allow/disallow it as a program trigger. But I guess the frimware developers aren't keen on it since it would be a major re-write and there is a current work around (separating your if's into multiple programs) that works perfectly. Elk rules only allow the first line to be a trigger. But that also requires multiple programs if you want multiple triggers.

Here it is in the least words possible. During a "wait" or "repeat" the program will terminate and start over when anything in the "if" section triggers. As pointed out above: If your dining room motion status changes during the wait (all "status" conditions are triggers with ANY change in status, Elk zones included). Since your variable is integer, it never triggers. .. so no prob. (State variables are the opposite. . .think "STATe and STATus)

The network module is capable of doing this sort of thing, but it depends on your security system. Since your security system is capable of being armed/disarmed from an iphone app, it is probably also able to be done via other network capable devices. But you will need the API on your unit to get the exact type of command and the exact syntax of the command.

Not exactly closed minded. Not to be argumentative, but I don't see you posting data either. While no system I have seen has thermometers at the ducts measuring the outlet temp and run the math to determine when the best time for that system to shut down is, why would they have not picked the most optimized time for the average install. You speak as though the engineers at Carrier/Lenox/etc are stupid and/or don't care about efficiency and that you know more than them. If some particular install is very different than average, you may have a reason to alter their engineering. Now if you have an older system that shuts down the blower the simultaneous to the condenser, then figuring in a little extra run time may help (or may be counter-productive) depending on what type of install you have. 1) If your ducts and your evaporator are in an unconditioned space (attic) you will want to dump as much heat from your conditioned space into the ducts and evaporator prior to the fan shutting down, otherwise it just ends up in the attic. 2) If your ducts and evaporator are inside the house (basement), you will accomplish nothing by running the fan longer. Eventually heat in your home will be sunk into the ducts/evaporator anyway. In this case, extra run time would be counterproductive (electricity needlessly used to run the fan and double counterproductive since the fan generates heat that ends up in your house). Depending on how you go about altering the fan run time, you may end up damaging the equipment and/or voiding a warranty. EDIT: CMartin. . . all's cool, I also got a bit defensive above.

Every home will have different details. But the companies that make hvac systems are in a huge battle with each other to make their systems the most efficient at the best price. They all continue to run the fan after the compressor shuts down for some period of time. The have a great wealth of knowledge and research on the subject to make that decision. The price of the equipment is the same regardless of how long the fan runs after the compressor shuts down, so it would be silly to think that they didn't set it to the most efficient time. Furthermore, the fan consumes electricity. Just because the air coming out the vent is still a degree or 2 colder than the air that is in the house for a few more seconds, doesn't mean that you are being more efficient. It may be that the fan electric consumption costs you more than that slightly cooler air is worth. Again, the hvac manufacturers are far more versed in this stuff that you and I could ever hope to be and it just doesn't make a lick of sense to think that they didn't already optimize this simple control.

I wouldn't. Any hvac unit that isn't ancient will continue to run the fan after the compressor is off an appropriate time to maximize energy efficiency. Running the fan after that would probably not be to your benefit.

Now this sounds interesting. Since my outlet is very close to the motor I would just wire it to the terminals on the motor. I'm not sure what wiring it to an rf control would do for me other than having to change the batteries very blue moon. Yes, you can just wire directly to the two same terminals on the motor itself that also go to the button. Some of the fancier buttons take issue with this because they use those two terminals to provide power to other functions on the button. But I think it was written earlier that you don't have that kind. Even if you do, putting a resistor in series with the I/O link can fix that.

A lot of people just wire the rf controller to the iolinc. Then you don't have to run wires back to the button or up to the unit. Of course you have to have some soldering skills to do that.

I don't think it is a bad idea to at least give it a try. If it makes no difference, then you can always go back to the old wall wart and use you nice power supply for something else. I will also add that the office dsl modem was 7 years old when it went all flaky on me. So it would appear that the power supply suffered some damage either just from time in operation or a spike hit it, or a bunch of little spikes over time got it. No idea, but I thought it was the modem at first, and clearly I was wrong. Just glad I tried changing the power out first.

Cause I just cut and pasted his stuff to address the question about an email at 30 min, 60 min, and then hourly. Yes, I would bundle the emails. Sorry I should have been more clear that I was answering the timing part of things and leaving your stuff to stand for itself.
