Normal 0 This unit can be reset, just a little complicated thats all.
Firstly, move slider to 'set program'. Then, on the left of the unit are two buttons, 'override' & 'extra hour'. Press and hold both together 'till 'inst' shows on the panel ( about 5 seconds ).
Then ( lots of fingers required! ) press and hold the two buttons mentioned above, along with '-' '+' & 'next on/off ( total of five buttons! ) until the user menu flashes up.
Now scroll to AL, which is probably showing a value of '1', this wants to be changed to '0' to turn off the 'service due' warning. To save this value, press and hold the first two buttons once more and then simply move slider back to 'run program'.
Job Done!!!
I hope this helps. It should certainly remove the annoyance of having to phone your housing association and then sit around waiting for them to show!!

Don't remember security code on thermostat


All Honeywell t-stats have a model # and a 1-800 #. Call them! Have your t-stat apart to see the model#. Or if you don't know how to take it apart call them first. Ask Mr. Google for Honeywell customer service #. Their customer service is usually %100 in helping me when needed.

Honeywell thermostat problems


The power from the transformer that provides 24 volt low voltage to power the T-stat may be gone. Check the 3 amp fuse and/or transformer, both located in the air handler (where the blower fan is).

CFS continues to flash on our thermostat (Honeywell energy star). I assumed this meant clean filter soon. I have cleaned the electronic filter but CFS continues to flas. How do I reset this.


CFS stands for "Call for Service". The thermostat will automatically display CFS after 3000 hours of operation. After service, run the unit. If automatically CFS would have disappeared. If not remove batteries and reset it. Helpful?

Need to know how to calibrate my honeywell RTH221


This thermostat is not field servicable,you cannot calibrate this thermostat.May want to consider moving it closer to return air of equipment, for more accurate sensing of building temperature. Why do you feel that it needs calibrated? Suggest setting another thermometer on top to verify its accuacy.

The timer light flashes twice about every 15 seconds


This may mean that the filters may need to be cleaned. According to service manual the unit has a "Serial reverse transfer
error at start up operation". Call fujitsu for service if the fault cannot be rectified.

Honeywell CM67ng thermostat not working. Have tried various programmes but still seems to have mind of its own. Can we replace with something else?


The cm67ng has a feature which attempts to get the temperature to the desired point before the actual time you set. In reality this "feature" just makes the device turn on and off randomly in a really bemusing fashion. You can turn this off with the following:

1, Set timer mode to "OFF"
2, Hold down "Info i" and press "prog 3" and "prog 4" together. Display Should show a spanner in the left hand corner.
3, press "prog 2"
4, repeated press "clock +" till the characters in the display after the colon read "OP" (the number before the colon seems to vary with model).
5, Press the "temp down" button. The 1 in the right hand of the display should become a 0.
6, Press the "info i" button to save your changes.
7, Switch the mode back to auto, the timer should now behave normally.

You should note that a number of other parameters can be changed in this service mode. Some of which could probably do bad things to your central heating system if set incorrectly.. So this is at your own risk! Either way it's best to read the installation manual before attempting to change anything:
