Focus pro thermostats
 
Anyone having problems lately with the Honeywell Focus Pro stats?
I installed 2 focus pro 5000's and 2 focus pro 6000's and had to remove them due to erratic operation. Just wondering if its just me.

Thank you

no problems whatsoever with all the ones I have used. what kinda erratic operation exactly are we talking about and with what brand of furnace etc. you gotta be very careful how you stick them onto the back plate to not damage pins etc and never use wire less than #18 gauge and make sure all the connections are down to bare copper if using older wiring.

I installed two pro 6000's in the last two weeks that seemed a good two degrees out of factory calibration. Both showed a consistant higher temp reading over true temp.
I've decided to go with thermostats which could be field recalibrated if nessesary.

Haven't had any problems with them myself.

I too would like to know what kind of erratic operation your talking about. I don't install Focus Pro's in volumes so I can't say much except I've never had a problem with the several I've dealt with/installed. I have seen many erratic or poor behaving thermostats though. They were all White-Rodgers or other odd brands. None of the Honeywell Pro series have given me problems.

Yes
 
I have had to pull a couple in the past month. Both would hang up on the desired setpoint and never cut off. I also have had problems in the past month with a couple of the 8000's. On one the touch screen was inoperative in places and the other just did whatever it wanted. You could stick it in heat and it would switch to cool and so on. I replaced all of mine with the same thermostats. Honeywell stands behind thier stuff well. It definately isnt the same stat it was 6 years ago but still heads and tails above anything else on the market. I have had several stats that the backlight wouldnt stay on even if told so. I let that issue ride. I install at least one a day and some days up to three. Percentage wise, I havent had any significant problems to get me really worried yet.

Thanks all for the input.
I've installed dozens of the focus pros over the last few years and they've been great.
It was just the last few that have given me problems. The first problem was (according to the customer ) that the differential was so tight that it was short cycling. I eliminated all other possible causes for short cycling before pulling the stat off. Unless I'm just not seeing it, the differential appears to be fixed and cannot be changed. If I'm wrong please explain where I can increase it to 2 degrees.
Other problems was that that the 6000 would only maintain 70 degrees in the house regardless of set point. The next day, thermostat would respond to set point properly.
New thermostat, problem solved. Just a lot of expensive gas used

On the first issue you need to ignore what the instructions recommend and set the CPH between 1 and 3. Any more then that and it will cycle way too often. I'm assuming this is gas forced air or hot water heat. If it's hot water I'd lean towards 1 CPH, and forced air, 3.

I've had a White-Rodgers touchscreen stat do this. Only in heating mode and it wouldn't shut off no matter what you did. Only thing to do was a battery pull then it behaved fine afterwards. Happened twice.
