can you post some screenshots of your goal definition and your dependancy settings and your TEC settings?
i tried something like this recently and it was confirmed as a limitation from the developers. just want to make sure we're talking apples to apples.
also for the TEC going too high of temp, that may be a setup issue.
Sure, thanks for getting back to me...
Here is the suface goal
Here is the tec (surface source) with the dependency box
Again, I don't know how to interpret the control value vs the goal and the dead band. My tec just does not come on. (I have been messing around so there may not be any logic left in the settings ;-)
the dead band is explained pretty well in the help
in your case you're telling the software when your goal is greater than the temperature, turn it off. but don't do it until it has gone above your control value plus the dead band. normally the dead band is a slightly larger value so that the control isn't turned on and off all the time.
are you sure that a turning off strategy is what you want?
(also thanks for the screenshots, i thought you were actualy using a TEC)

"the dead band is explained pretty well in the help"
I agree that there is good explanation in the help files but when I can't get something to work, I start questioning everything. The image shows it as a differential value but I wasn't sure if it was specified as such or if it was generated by the software based on an actual temperature that the user entered.
(Also I didn't know that the explanation of the 4 toggle modes was hidden under some type of click-expand dohickey)
"in your case you're telling the software when your goal is greater than the temperature, turn it off. but don't do it until it has gone above your control value plus the dead band. normally the dead band is a slightly larger value so that the control isn't turned on and off all the time."
This is what i want, correct? You say plus the dead band... this is because I have the temperature of my goal set as "minimum value"?
"are you sure that a turning off strategy is what you want?"
I just spoke with my electrical engineer and he corrected my thining on this... I thought the TEC shut off but it actually switches polarity and starts a cooling cycle and flip flops back and forth. So no, I am not sure that is what I want to do.
"i thought you were actualy using a TEC"
I don't know how to create a TEC and cant find any tutorials for it. When I say create a tec I mean model the actual TEC we are using and the "engineering database" is extremely lacking unless you shell out the cash to by the electronics add on. If you want to start another thread on TEC modeling I would be a very willing subscriber.
SO.... If I have it set to come on until it reaches the goal plus dead band, why doesn't it come on?
build a really simple example that you can post. if you can't make it work in a simple model that you can control how it should come on and off, i'd submit to your reseller. haven't had a chance to build my own and check but i did have a problem with them not coming on/off a few versions back. maybe that problem has come back.
