NOTE: Only the installing contractor should set System Settings.

The System Settings Menu gives nine more ways to get the most from the thermostat.
The information below describes how these features enhance thermostat performance.
Equipment Setup – Make selections about the types of equipment used in your heating/cooling system.
First, choose what type of equipment is used for the 1st Stage Heat.
Choices are: None, Furnace (e.g., gas forced air furnace), Strip (e.g., electric baseboard
heating), or Heat Pump.
On 9825i2 models, choose 2nd Stage Heat.
Choices are: None, Furnace, Strip, or Heat Pump.
If Heat Pump is chosen for the 1st Stage Heat and Furnace is chosen for the 2nd Stage Heat, two new menu items will appear on
the Equipment Setup Menu; Comp. Type and 2nd Stage Fan.
The Comp. Type allows you to determine how 1st and 2nd stage heat work together.
Add-On – 1st stage heating compressor on the heat pump will be turned off when 2nd stage heating is activated.
Standard – 1st stage heating compressor will continue to operate with the 2nd stage furnace for added heating.
The 2nd Stage Fan determines how the fan will operate.
Plenum – Allows the furnace to control the fan.
ON – Allows the thermostat to control the fan.
