Negative Positive
Title: Defective Design
Review: I bought one of these for a simple 2 wire setup (R and W wires). From the manual it looks like you can use it for that. The first one I installed did not work and the customer service person asked me about my setup, we checked that the wiring setup I had was good (touch red to white to make sure it goes on), but it did not work, so they told me it was defective. I went to get another one, and same thing. The think is, if you look at how it's made, it looks like they have connected the wrong posts -- the metal connector that works when you touch the wire to it is not attached to the W wire screw. I tried a different thermostat and it worked fine. So either both of the these CT31A thermostats I bought were defective, or the thermostat was mis-manufactured with a flawed design, or it's not designed to work with a 2 wire setup (though the manual does not say so).Would love to hear from Honeywell what the issue is with this thermostat.
Is the review positive or negative?
