I want to turn off the adaptive recovery. How do i do it?
On the Pro4000 model you hold the 2 arrows until you go into setup mode. Then arrow up ONLY til you get to option 13. The display will read 13 and 1, press the DOWN arrow and it will read 13 and 0. This turns off Adaptive Intelligent recovery. Now hold the 2 arrows til you see the normal display screen. You are done.
I just did this with a Honeywell tech rep on the phone.

The thermostat is not advancing through each program. It is stuck on program one, even though the time is changing on the thermostat.
Sound like you need new one... take a look on amazon ecobee3 Smarter Wi Fi Thermostat Remote Sensor. It's not worth repairing it..

I have a Honeywell RTH7400D programmable thermostat installed and working fine, except that I cannot change the display settings from farenheit to celsius. The package stated that it was both farenheit and celsius capable but the manual does not tell you how to switch it. I live in Canada - everything is in celsius except my thermostat.
A solution would be greatly appreciated.

My thermostat was set on celsius and couldn't get it to change back to fahrenheit. My son suggested pressing both up and down arrow buttons at the same time and it worked. It changed back to fahrenheit.

I just noticed the display stopped working. The fan will turn on when I flip that switch, but it is the only thing that responds. I checked the fuse and everything there appears to be in order.
Hi, take a look on amazon for replacement, here: Defy Mother Nature with our Best Buy. I hope this was helpful. Cheers

I have a two zone thermal control on my boiler one s a honeywell cm61 and the other is a honeywell r6660d. I believe the r6660d is the base unit recieving a radio signal from the cm61 as it is wired to the boiler. I now have both the green LED and the red LED showing. why has the red LED come on and what does it signify?
The problem is that the 2 units are "not speaking to each other". this could be caused by low batteries or a loss in signal caused by a powercut or an objection in the way of the 2 units.
first you need to turn the power off to the r666od (or otherwise known as the HC60NG) for 10 secs, then turn back on. then hold the grey button in for 15 secs. release then hold in for a further 5 secs.
go to the honeywell cm61 press the off button. hold temp up. temp down and prog 1 in for 3 secs until the dipslay goes to INST. at this point release all 3 buttons then press the i button until a beacon starts flashing.
this is now the end to your problem.
N.B the reason the green light was on is because the man override button will have been pressed.
hope this helps

I have an older (~20 yrs) honeywell chronotherm III programmable thermostat controlling an oil furnace and a seperate AC. It will skip over periods, get stuck in periods, not raise the temp, not stop running funace when temp is reached, etc. I've tdecided it's time to replace it, but I don't know what with. Is there a cross-walk somehwere that says "if you had x, you should now get y"? How do you know what's compatible? How hard a job is it for a person (my son, not me!)with computer hardware and automotive skills but no experience in heating to do? Should I call a pro, or is this a DIY project?
Thanks,
Clueless

We just replaced the batteries in our Honeywell RTH230B controller.
I did not turn off the Heat/Cool switch before removing the old and reinstalling the new batteries.
Now, with the new batteries installed, the battery icon is flashing and the controller won't turn on our pellet stove. I checked the battery voltages and the new batteries are fresh.
Is there some type of reset button I need to press to clear the low battery error?
I had this same problem today. I called Honeywell and they said the flashing broken battery symbol may mean low batteries, or it may mean the battery type is incorrect. They recommend only non-rechargeable alkaline batteries. I was using rechargeable NiMH batteries. Even though they were fully charged, I had the flashing battery symbol and the thermostat relay would not work. I replaced with alkaline, the flashing battery indicator went out, the thermostat works again.
Odd that it worked for 3 months on the rechargeables after first install. I did notice the broken battery symbol came on after the first few days, but I checked the battery charges and they were good, so I disregarded the symbol until the thermostat stopped working today. Apparently there is something about the NiMH performance characteristic that the thermostat doesn't like.

How do I switch the rth7600d thermostat from reading in Fahrenheit to Celsius, and vice versa?
When you do your system setup, Function 320 controls your temp. format. Set Function 320 to 1(celsius); Then press DONE. This will solve your problem.( Function 320 is defaulted to 0-Farenheit).

A/C won't kick on w/ Honeywell RTH230B The thermostat went out and needed the batteries changed. I changed the batteries but now the AC unit will not respond or switch on even after waiting the 5 or so minutes for compressor safety. I have tried to reset it several times over a period of a couple hours but still no luck. The unit has worked fine and the AC was running earlier today without any issues.
Hi,
Okay it seems that for some reason the battery change scrambled the brain of the t-stat... that happens...
To fix it you will now have to go into the "Installer Menu" and reset the paramenters of the t-stat.
If you have the Installe brochure then you can look in there and then set the tistat for "heat/cool" and also to "auto fan" and then to "auto changeover" These should get you back to cooling again...
No big problem, just a small programming issue...be patient and if you do not have you book don't worry... you can look it up here...this tip tells you where and how to find any of the Honeywell t-stat manuals.

whdoes it mean of wake, return, sleep and leave on honeywell digital thermostat
I believe it means (I assume winter weather in my example):
1. Wake - This is the time you wake up and you would set the temperature at the time you want it then. So, your temperature throughout the night might have been set at 63, and if your "wake" time on the thermostat is set to 6:00 am and 68 degrees, then your system will automatically adjust the temperature setting to 68 degrees at 6:00 am.
2. Leave - This is the time that you would typically leave your house for work. You probably don't need to heat or cool your house that much during this time especially if no one will be there. So, let's say you leave for work at 8:00 am. You would set this time for 8:00 am and 60 degrees.
3. Return - This is the time you get off work. Let's say you get off at 5:00 pm. You would set this time for 5:00 pm and 65 degrees. Then the system will start warming up at 5:00 pm and will be warmer by the time you get home.
4 - Sleep - This is for when you go to bed. Following the example, let's say that you set your temperature while sleeping to 63 degrees at 10:00 pm. Then, the system adjusts at that time and will adjust again as soon as then next parameter is met, which at this point would be the wake time.
This is usually for a Mon - Fri schedule and then a separate one for the weekend.
