I recently installed two Honeywell TH8320ZW thermostats. The installation and pairing process was very straightforward. Now that I can control them from my phone, I wanted to provide some feedback on the app controls themselves. Specifically, there are two areas that I think would really benefit from some UI changes:
The way it cycles through Heat/Cool/Off is really poorly designed. If I have the heat on and I want to turn it to 'off', I can't do that without first cycling through 'cool'. That in turn unnecessarily cycles the AC compressor, placing wear/tear on the equipment. Suggestion: Create a way for the user to select 'Heat', 'Cool', or 'Off' directly, without having to cycle through other states first. (side note: I don't change the fan state that often -- I tend to leave it on auto. However, for those who do, I can see the same sort of UI issue with that control as well)
Second, it is very, very difficult to select a specific temperature on the heat/cool sliders. Maybe I have fat fingers or something, but selecting ‘72’ on those darn sliders is nearly impossible. I can generally get within a couple degrees, but pulling my finger off the slider invariably (and unwittingly) adjusts the temperature up or down a couple degrees. This really needs to be improved.
Overall, it’s fantastic that I can control the thermostats from my phone, so please take this feedback in context – great solution overall that just needs a couple tweaks.
