Sometimes the furnace does a better job than anticipated, i wouldn't worry about it, especially if the furnace shuts off.
the setpoint is the temperature you want it to be
cycle lenghts are determined by how much recovery you are requesting. for instance, in the morning when you wake up, you want the temperature to be at its setpoint. what the thermostat will do is make the furnace run a limited lengths during the recovery process.

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.

I just installed a honeywell 5-2 progammable thermostate.. Everything is hooked up fine and I have my days, hours wake, sleep, leave...etc all set, but when it goes on.. for example, I have it set for...


You didn't include a model number, so it's hard to know for sure - but I'll take a stab at this one. Many of these t-stats have a programmable offset to reduce "hunting". This can be as little as 1 degree or more than 2 degrees.

This means if you set the offset to 1 degree and the room temperature to about 65 degrees, the furnace will heat the room until the t-stat registers a rising temperature of 66 degrees. The furnace shuts off and will not turn on again until the t-stat registers a falling temperature of 64 degrees. The average is 65 degrees, and prevents the furnace from starting and stopping numerous times instead of just once with the 1 degree offset.

You can further reduce the number of furnace start and stops by increasing the offset to 2 degrees. This would work like this when the t-stat is set to 65 degrees and the room is cool:

Room Temp Furnace
63 On
64 On
65 On
66 On
67 On
68 Off

The room is now warm and heat or furnace is off. The room begins to cool like below:

67 Off
66 Off
65 Off
64 Off
63 Off
62 On

With a 1 degree offset, the room temperature varies +/-1 degree (about 2 degrees total). With a 2 degree offset, the temperature about varies +/ -2 degrees (about 4 degrees total).

Also, when the thermostat shut the heat off, the heat that was made is delivered to the space instead of wasted by sending outdoors - so the room will get a little warmer even though no fuel is being burned. The same holds true at the other end. When the t-stat turn heat on, fuel is burned, but there's little heat until the source has reached the optimum temperature and then the heat is delivered to the space.

I hope this helps & good luck! Pleas rate my reply - thanks!

Message: "in recovery"


the "in recovery mode" is refering to a thing called energy recovery management its one of the features on your tstat what it does- when you are using the program on your tstat the "in recovery" starts your unit early so if the tstat is set to be 70 degrees at 8 in the morning when 8 o clock hits it will already be 70 degrees in your house you can turn this feature off if you want in the installation setup codes

Honeywell RTH230B a/c problem


if you set the thermostat on 70 and your house won't get ant cooler than 72, there is a problem with your system,not your stat. I'm thinking you are low on refrigerant if it is somewhat working. when the unit is running, if you can get your hand on the larger refrigerant line under the black insulation, it should be cold, about 55 degrees.

How do I get my honeywell system up and going?


for now, put switches on thermostat to hear and press the up arrow button to the desired temp. All your programed temps will take more explaining and it would be best you secure a owners instruction book from home depot. oif anything, buy thr same thermostat and either keep it or return it . I'd keep it regardless, read the pmphlet,program you heat and a/c before returning for refund. Don't destroy packaging and give them back everything. You will also need two AAbatteries. Good luck.

Honeywell rth230b won't shut off heat


Sounds like a relay sticking. Possibly in the thermostat or possibly the furnace relay at the furnace. The next time it happens, unplug the thermostat from the wall. If the furnace still runs then it's the furnace relay.

Hope that helps...
