Yes, this is the model that you will need.
Yes, if I remember correctly, the number of stages in both heat and cool are programmable.
This thermostat will work, as long as your forced-air heating is only one stage.
We recommend that use the TH8110U1003 touchscreen thermostat. If you want a digital thermostat without touchscreen capability, the TH6220 series would be a more affordable alternative.
Yes, it has an EM Heat setting (only for heat pumps w /auxiliary heat). The thermostat controls Emergency and Auxiliary Heat and the compressor is locked out.
The model # of the thermostat is TH8320U1008 (3H/2C + Heat Pump). The model # of the outdoor sensor is C7089U1006.
Yes, the TH8320U1008 thermostat will work for your application.
This means that your auxiliary heat is on. This may be set as your second stage and may be coming on when there is a call for heat.
It sounds like the system is having difficulty reaching the set point and it needs the extra heat from the Aux heat strips to reach the set point. This prevents the heat pump from running at full load for days at a time. When the weather gets cooler, the heat loss from the house goes up and the performance of the heat pump goes down at the same time. Eventually, the weather gets cold enough that the heat pump cannot keep up with the demand by itself, and the heat strips (Aux) are used to make up the difference.
This will depend on the programming times you set up, the temperatures you set the thermostat to, and the type of heat source you have. By simply programming the thermostat to lower temperatures when you are not home, you can have significant energy savings.
You will need to program this thermostat to use the "Auto Changeover" function. To do this, change the Manual Changeover setting from "0" to "1" as described on page 2 of this product manual http://s3.pexsupply.com/manuals/1249544874360/Honeywell_TH8110U1003_Setup&Test_PocketGuide.pdf
You are right, it CAN do it. You have to have the INSTALLER manual though and get into the INSTALLER setup to enter the proper code. It is not in the user manual.
It can do it. You need to go into set up and change the value of setting 300 from 0 to 1. Then you will be able to select auto in the System portion of the screen.
Check wiring setup to ensure it is correct for your application, i.e heat pump,furnace etc. Setup functions should be checked (0170 etc).
Roget - You have to go into the installer setup and change the setup function 0300 to a '1'. The 'AUTO' will then show up.If you don't have an installation Guide you can download one from Honeywell. - Be Blessed.
