The only thing you control via the ISY is your thermostats and the subsequent programs for it to behave how you want? Obviously your system is how a normal zoned system would be designed, but I feel like there are scenarios where I would want individual control of dampers without having to adjust said thermostat to have that area's damper close/open. Are you able to do this in your current system? I'm assuming no since the dampers and thermostats are wired to the zone controller and it makes changes based on set point.

Can you send me the thermostats, dampers, and the zone panel you installed?

Yes, this is really not going to be used in a heating scenario in any capacity (I live in Florida). From an A/C perspective, I like to keep my office colder than the rest of the house. Basically I'm just trying to figure out a way, again, if it at all, to keep a single room multiple degrees cooler than the rest of the house.

Yeah, I guess that's mainly what I am asking/trying to figure out. In theory, I could program something like the following: -Main thermostat is set to 76 -If wireless thermostat is changed to a set point lower than main thermostat, reduce main thermostat to match wireless set point (thus turning on the system) and close the dampers in the other rooms -Once wireless thermostat hits set point, change main thermostat back to original set point and open all dampers -If during operation the main thermostat increases 1 degree, open all dampers Ultimately, I am assuming that with dampers cut off to the area where the main thermostat is mounted, it is not going to drastically change temperature which should let me control it with the above scenario/programming. There's also the ability to just scrap this idea as a whole. The dampers are a phase two installation after the new HVAC so if I change my mind on doing this, no big deal.

I'm looking to create a pseduo zoned system using programming and dampers that I can control. In theory I could just buy a zone controller and hook the dampers and stats up to that, but I'd rather not.

I am in the process of purchasing a new house and doing a full replacement of the original HVAC system from 1997. We've settled on a multistage heat pump system that is being engineered to allow damper control without adverse effects (heat/pressure buildup when closed, etc.). I mainly want to be able to turn down a wireless thermostat in a separate room (let's say my office), close dampers where desired, and cool the single room without drastically changing the temperature in the rest of the house. I am now struggling to find the best option to integrate this system. I can control the dampers via Insteon On/Off modules with ease, but deciding on the thermostat has been a pain point. The Insteon thermostat does not support heat pumps in addition to its reliability issues. The Venstar + Insteon adapter seems like a decent option for main thermostat, but I'm not sure how the wireless options work, if at all. I also see there are some abilities to integrate other wireless thermostats on the market via the network module. Can anyone suggest a good way to do this and what thermostat/wireless options I should look at? From a programming angle, do I need to write it out so that the main thermostat actually adjusts its set point to turn the HVAC on? For example, main thermostat is set to 76 and I turn down a wireless thermostat to 73, I assume I then need to change the main thermostat set point to 73 so the unit comes on and the dampers close per my design. If that's the case, should I then have it change the main thermostat set point back to 76 once the wireless set point hits 73?

I've spoken with support (Steve) a few times, but he really just gave me info on how an all on could happen due to noise. He didn't mention any real fix and said PLM replacement/new PLM firmware is not known. This seems to contradict what Michel has said previously.

Michel, Not sure what you're referring to - I was under the impression this is a firmware update that would require PLM replacement.

Just an update on this - I spoke with SH support today and they had no idea about this issue or a pending firmware upgrade. If the devs are aware of the issue/working on firmware, they have not informed support.

Thanks for the diligence and info - makes sense. I assume if I factory reset said device, it would have to go into linking mode again.

No problem, thanks.

I've used New Insteon Device to add all of my devices. PLM v9B

Based on the PLM link table after adding a new device post deletion, it does appear that it has marked the link correctly and allowed the new device to take over that slot in the database. I still just find it odd that it doesn't need to go back into linking mode if I re-add the deleted the device. When I re-add the deleted device, the PLM links exist, the device links exist and match the ISY links, so I'm sure everything would probably work without issue.

When deleting a device, does the ISY actually delete the links from the PLM as well? I deleted a device and viewed the PLM link table and said device was gone. However, oddly (in my opinion), when I added the same device back, the PLM did not beep and go into linking mode. Is this intended behavior? I'm not seeing any issues, but am curious for my own knowledge.
