USNRET Posted July 3, 2015 Share Posted July 3, 2015 (edited) One of my thermostats occasionally decides to reset itself to 68 degrees. It is a Honeywell basic thermostat and is set to hold 78 (no programming / schedule has been coded). Every so often, always at night, it changes to hold at 68. I have gone as far as replacing the thermostat and it still happens. The battery has been checked and replaced. The wife certainly doesn't change is as she hates colder temps and I have never seen either child touch a control and the times it happens they are deep asleep. Wired correctly and connections are tight. WTFO???? Edited July 3, 2015 by USNRET 1 Quote Link to comment Share on other sites More sharing options...

USNRET Posted July 3, 2015 Author Share Posted July 3, 2015 With all the problems you have reported, have you thought of moving? Too much hassle and no money. This zone is the one that I have had zero problems with (except this now). Finally got the others to run fault free for a while now.........KNOCK ON WOOD Quote Link to comment Share on other sites More sharing options...
oldtimer Posted July 3, 2015 Share Posted July 3, 2015 OK that wasn't much help. Have you thought about making sure you aren't on top of an ancient American native burial ground? 1 Quote Link to comment Share on other sites More sharing options...

oldtimer Posted July 3, 2015 Share Posted July 3, 2015 Well then something is obviously haunted. I doubt it is the thermostat since you replaced it. Wait to see if your kids float to the ceiling. if they do then move regardless of cost. The only other explanation is you have a thermostat poltergeist. That would take over whatever thermostat you install. Quote Link to comment Share on other sites More sharing options...
USNRET Posted July 3, 2015 Author Share Posted July 3, 2015 (edited) The only other explanation is you have a thermostat poltergeist. That would take over whatever thermostat you install. Got it, perhaps the kids can dust the ceilings while there. The ghosts seem to only appear in the dining room thermostat as they choose not to tamper with the others. You may have something there oldtimer as a smoke detector on a 22' high ceiling decided to twist out of its mount and dangle from the wiring in the same area.

Guest thesloth Posted July 3, 2015 Share Posted July 3, 2015 If you have a mulitmeter then maybe check the control voltages? Could be low or high and causing the thermostat to freak out maybe. You should have 24VAC. Quote Link to comment Share on other sites More sharing options...
totalcomfort Posted July 3, 2015 Share Posted July 3, 2015 Step one chunk the Honeywell!! Step 2 buy a emerson blue t-stat. Step 3 install . Problem solved!! Been in HVAC for over 20 years and run my own company. Honeywell always gave me fits with weird problems, will not use them anymore. Their commercial grade controls are very good. If you need help wiring it up PM me and I can talk you thru it. 2 Quote Link to comment Share on other sites More sharing options...

A Priest Just kidding doesn't sound that bad, I do like the idea of the kids dusting the ceiling. Lived in a 100+ year old house once that had many problems like this and much more but nothing scary enough for us to move, but it did change our opinion of some things for sure. 3 Quote Link to comment Share on other sites More sharing options...

totalcomfort Posted July 3, 2015 Share Posted July 3, 2015 (edited) Step 2 buy a emerson blue t-stat Given the above wires (not heat pump) what model / part number? Can you sell?Go to your local HVAC supply store tell them you need a Emerson blue tstat single stage for gas/electric heat.I can get you one and ship it to you, but you will save money buying local most of the time. You should not have to pay more than 60 to 65 $ for it. You have a easy hook up. Common wire colors Y=cool G=fan W=heat R= power 24volt.. When you get tstat it should have a red jumper wire between RC/RH. If not make one to jump these together, then connect the red wire to these. Make sure you turn breaker off to unit so you don't short the transformer while changing the Tstat. The blue wire in your pic is common and goes back to C Edited July 3, 2015 by totalcomfort Quote Link to comment Share on other sites More sharing options...
JJkizak Posted July 3, 2015 Share Posted July 3, 2015 The dude is right, junk the Honeywell which is sporadic due to poor battery contacts and programming and go to the Emerson which is rock solid with the blue screen. My local repair company will only install these units. My other Honnywells always required constant monitoring for spasdic changes.

Moderators Travis In Austin Posted July 3, 2015 Moderators Share Posted July 3, 2015 Honeywell makes great Turboprop engines, controls not so much. Is this it? 58 on Amazon with free shipping if you have prine. http://www.amazon.com/Emerson-1F80-0471-Programmable-Thermostat-Display/dp/B0035UGKJM Quote Link to comment Share on other sites More sharing options...
Moderators Travis In Austin Posted July 3, 2015 Moderators Share Posted July 3, 2015 Carl, Would a wifi capable tstat do you any good at all? One you can control from phone? Quote Link to comment Share on other sites More sharing options...
