Question about Heating & Cooling
Unwanted non-deletable schedule exists. When moving from Sleep schedule to Wake schedule former schedules appear even though correct schedule is placed in memory and is visible as desired schedule for wake mode. Is there any way to purge entire memory and go to default so that I can remove unwanted schedules. This condition only occurs from Sleep to Wake mode. All other modes work correctly. Thanks
Remove the batteries and any power source for 10 minutes. This should go back to factory defaults. Sounds like a stat problem honestly. I would exit the program and change temps manually at all times.

In the set up mode are you sure the lock was not turned on. The set up mode has a different book for the installer. Do you have the book if not check with Honeywell or let me know.

If your manualy setting the program and it kicks itself off, then your therm is bad, look for your warranty paperwork, or call the distributer and give them model and serial, they can point you in the right direction. If your setting a temp and not manualy holding, then it will set back by default. Check your other settings, ensure they work as well..

The thermostat has a function called "Adaptive Intelligent Recovery".
This feature allows the thermostat to learn how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.
You can turn off this function. Download the installation guide at the next link:
and look for funcion number 0530 Adaptive Intelligent Recovery. In this manual you also find the way to do a reset with the function number 0710.
I hope this solves your problem.

The unit is designed to run the indoor fanmotors continuously when in cooling mode on both indoor units (evaporators). The reason is that this circulates the air and the temperature thermistor or sensor is able to sense return air temperature and in turn start or stop the outdoor unit and compressor as required according to the setpoint temperature. The reason for either unit not reaching setpoint temperature can be a couple of reasons. A) Incorrect design - the unit may be too small for the application. You can calculate this roughly at 650BTU per square meter of room in a relatively warm ambient climate. Or secondly B) The outdoor unit has leaked and is short of refrigerant. You can check this when the outdoor unit is running by feeling the thicker copper tube on the right hand side of the unit. This should be cool to cold. If no temperature difference is felt, it is short of refrigerant. Hope this helps you. Goodbye
