Why does my Honeywell thermostat state temporarily set at 68 degrees? A few days later, it will be set at 62 degrees without anyone touching the thermostat?


It's a programmable thermostat. When you change the temperature, it will say temporary until the next programmed schedule starts or a set amount of time. You will have to program the thermostat to the correct temp settings you wish to have, or you can push "HOLD" after changing the temp to make it stay at that set point. Hope this helps!

Time and vacation symbol flash-all buttons non responsive - how do I fix


Hello there,

Are you SURE the floor temp sensor is wired correctly Page 8 of the Manual ???? It should be across 1 and 2 . if it was on the number 2 and 3 connections, this would simulate a 'remote switch' check the wiring of the floor sensor carefully in the back of the unit.

Something odd about the 'Vacation'mode' setting. You said it has no remote switch but only this 'remote switch' can disable it. by going open circuit. which sounds suspiciously like something is across pins 2 and 3

Time flashing is 'Temporary override'


Read page 16 AND 17 (flashing as you say) of the user manual

Change factory set date on thermostat


This is just general information for most thermostats. Press the set button until the date comes up. Press the up or down temp. buttons to where you want it. Press the run button to lock it in. I hope this helps.

My rth230b temperature up and down control buttons are now not operable, ie they do not move any function up or down. whether it is a clock reset, or changing the temperature.


Verify your battery is good. Make sure it is in manual and not program by using the mode select button. Verify its set to heat. The first push will show the set temp. Push twice or more to change the temp. With that all said if it is still locked out you might have a short. If its been less than a year you can call the support number on your installer sheet and check for warranty info. I didn't see one in the instructions but to be safe make sure there is not a lock out feature too.

Honeywell programmable thermostat


It sounds like you might have the same problem that we have. I read the manual and it says that thermostat has a special lock to prevent tampering. It could be locked. If you override it only last a while and goes back to its original settings. The manual says you need to contact the person who installed it. In our case the person who was in charge when when we had it installed is no longer with the company. We don't know who installed it.
