Almost easy installation with a stupid flaw.
This was almost easy as pie, until I went to screw everything back in place. The Temperature knob is positioned right on top of—almost over the wall mounting screw. So how am I supposed to screw this thing into the wall. There’s no drill bit extender in the world that can do that job. Mine must be defective, since I’m not seeing anything like this in other reviews...?

Hi Andy, I recommend to start with the screw that has wiggle room to accommodate the 2nd screw better, if this doesn't work then you may need to get a different electrical junction box, call us for better assistance 855-223-3887.

    Disappointed! Installed 9/2021-unit failed 1/2022
    Installation was easy, but temp was always 10° off. We set the dial at 72 for room temp of 62. Unit worked fine until last night. After having temp set at 62° for weeks, woke up to 85° in the room today. Unit would not turn off-we had to flip the breaker.
