My batteries died on mt heat control, I changed them and now have nothing


http://www.gogeisel.com/geiselonline/support/Honeywell/CT3300_CT3355.pdf this is the programming manual- they have a note that if you show low battery after replacing the battery- put the battery in backwards, wait 10 seconds, then put the battery in correctly again to reset it- you will have to reprogram the clock time and date and any settings you had previously.

Trying to set temp on honeywell t-stat


I believe what your experiencing is the 75 degrees is the hold temp position...the display then reverts back to the actual room temperature...it doesn't mean the set temperature changed back to 65 degrees. Try to reprogram the thermostat schedules, and try not to use the hold function...just the temporary hold. (which is bumping the programmed temperature up or down until the next programmed period)

Honeywell thermostat rth 1108


First change the batteries. If that does not help, perhaps the user manual will give some hint as to what this means. I hope this helps.

Honeywell thermostat keeps going to "leave" status and increasing the temperature in our house and we can't figure out how to reprogram it to stop

My remote in my keys no longer work to unlock my doors or trunk. I have changed the batteries in the keys, the light blinks when I push it. What could be wrong? I have a 2001 GS300


Most likely: You have to now "reprogram"your key fob and car to recognize each other. Look in your User's Manual for the car or, if it's an aftermarket fob/lock system, look in the user's manual for that. If there's nothing about battery replacement/reprogramming procedures, and it's a factory system, head into a dealer to reprogram it. It could run you up to $120, but that's cheaper than buying a new fob or system. If it's and aftermarket system and the manual says nothing, go to the place you had it installed (repair facility, Future Shop, etc) and have them reprogram it. If they installed it, they should know how to reprogram it.

Keep in mind, that's only the most likely option. Another possibility is that the receiver in the car, transmitter in the remote, or lock actuators/relays, etc in the car are the issue. It may not have been batteries in the first place at all. That said, it was most likely the batteries, and your best bet is trying to figure out how to reprogram the fob and car to recognize each other.
