Wiring in a 208A KTU.
« on: October 16, 2017, 07:18:59 AM »
OK.... I now have 2 of the 3 208 KTU's for my system.... and I'm trying to wire them in..... so far... no response.... I have power and the ICM line is established... but when I go to test it.... nothing. so far, I have the TO link in, Term #25. the specs on the 212 also show a link to the CO (207: 5B to 212: 17A.) the first 3 control leads are in place. (C: 18, 19, 20) and are attached to 2, 3, and 4A on the 207. I temporarily shorted terms 3 and 4 to see if the A-lead was working, nothing. when I pick up the ICM the 207 jumps to life, but nothing from the 208. what am I missing? what do I need to do to make sure the units is working?
