4D. O/B Configuration

Installation > Advanced HVAC Options > O/B Configuration

This configures whether the O/B terminal for the heat pump reversing valve will be energized during cool (O) or heat (B) mode.

4E. Fast Second Stage (for homes with multi-stage systems)

Installation > Advanced HVAC Options > Fast Second Stage

If the user has multi-stage equipment and would like to have the ability to rapidly heat or cool on command, then set this feature to the ON position by pressing the ENTER key. Once in this mode, the thermostat will instantly turn on all available stages when the set point is manually changed 3 degrees or more from the current room temperature.

4F. Smart Fuel Logic (for homes with a heat pump AND gas furnace)

Installation > Advanced HVAC Options > Smart Fuel Logic

The thermostat has the capability to control dual-fuel systems without an outdoor temperature sensor. The thermostat can determine when the heat pump is no longer efficient and can perform system changeover to the gas furnace. In the Smart Fuel Logic menu, choose:

Standard: The default setting

Comfort: Brings on gas furnace sooner at higher outdoor ambient temperatures

Economy: Brings on gas furnace at lower outdoor ambient temperatures
