Pretty simple question I hope:I have a dual thermostat house (2 stories) both are controlled by a Honeywell rth221B1000, which is a real basic programmable model. Recently, the downstairs one has effectively become stuck on a heat setting. I've taken it off, pulled the batteries, and fully re-programmed but issue remains.The issue does NOT occur on upstairs unit, so my assumption is it is NOT boiler related. I've checked the low-voltage wiring in the unit and it is all secure (I previously knocked the unit off the wall early this week by accident, however I believe this to be unrelated as it worked fine for a couple days before exhibiting current issue).Right now it's reading a temperature of ~78°, although the thermostat shows it is set to 60°, and the baseboards are giving off heat.The only other thought is my repeated removals have made the reconnection be a bit iffy, but I've reseated it several times and the issue remains.Thanks for any help! via /r/DIY http://ift.tt/2C6wxMS
