Howdy all,
I am having a lot of trouble getting an Aprilaire 8870 to work. At this point I'm just trying to get it to work as a standalone thermostat before I add the 8811 into the mix. I hooked it up according to the book, but I'm no sure what to hook into the common. THere's just a dotted line in the diagram. WIthout hooking it up, the unit wouldn't power on. By using a volt meter I noticed that the W1 connecter is getting some juiice, so I jumped a wire from the W1 to the common. Now, the backlight on the unit comes on, and the HVAC system kicks on, but the unit itself won't boot. I've dumped about 3 hours into this, and I'm stuck at this point. Does anyone know what I'm doing wrong?
The diagram I'm following is here, and the only modification I've made is to jump a wire from C to W1. If I don't do that it won't power on at all. The only wire I'm not using from the thermostat is the blue one.
Thanks,
Target
