Hello again Airtouch Users!
First a big shoutout to the community for all of the work that’s gone into integrating Airtouch 5 with Home Assistant, its progressed really far over the past couple of years and I am very happy with the integration. I am currently using @TheNoctambulist integration and have had a few different interactions with @smitcoracing as well, both of you are legends for all of the quick responses and help to this group! Thanks guys
Thought I would reach out and ask everyone how the overall performance of the Airtouch is, because I had some questions about my AC system performance vs others. How well does your Airtouch 5 track each zone temperature to setpoint temperature? I have ITCs for each of my zones and the standard behavior I notice is that it doesn’t appear to ramp the unit up until I am ~1 degree above my set point. The dampers are opening to 100% before that, but the actual AC compressor/condenser units do not start putting in the work to really keep the unit down to the set point. Ill provide a basic example from a summer afternoon for a better visual.
In the below graph you can see damper percentage for this zone on the top, a temp delta in the middle (ITC temp - zone desired temp) and mains draw at the bottom.
You can see the zone open to 100% very quickly after the delta crosses the 0 degree point, I think this part is working perfectly. However, looking at the bottom graph, you’ll notice the current draw didn’t really kick up until about 1.5 degrees delta where the unit then brought the zone temp down by about .5 degrees and its steadily been increasing for the past 90 minutes with no real change in power draw from the unit. This is my largest zone in the system, but I dont think that matters in this scenario. I don’t remember the exact size of the AC unit for this zone but it regularly pulls closer to 3000 watts when you can really hear the condenser fan cranking and the unit moving some air.
So I guess my question\concern is, does this seem somewhat normal to others behavior? I would expect that unit to ramp up a little bit more and even overshoot the desired temperature a little bit, not stay regularly 1 degree above it when there should be heaps of capacity left in the unit. I am slightly worried that my Airtouch commissioning process may have not been completed correctly as my faith in the installers of the system is pretty low.
*side note, the bottom graph does include whole home power draw, so the ripples and noise are likely not part of the AC units power draw.
Thanks all!!
