I just bought new programmable z-wave thermostats (Honeywell TH8320ZW). I thought I had the wired correctly, but I woke up to a pretty chilly house this morning. The fan is working, but it seems to be blowing cool air. Here is a picture of the original wiring for the upstairs thermostat:
Full disclosure: A year ago, I replaced this thermostat, but realized I had ordered the wrong thermostat, so I put the old one back. There is an outside chance that I wired it back incorrectly, but that would not be typical of me; also I have not noticed it not working properly.
Can someone help me figure out what I did wrong?
OK, I figured out part of my problem, but it presents another question. I have not configured the thermostat (I know stupid mistake, but in my defense those pages were stuck together in my manual). However, there does not appear to be a configuration in the manual that matches my wires. The closest appears to be 2H/1C Heat Pump (with aux heat). If I am correct, and reading the foot notes correct, I need a jumper between E & Aux, and the L is optional. Am I correct?
