Two Stage Systems

A 2nd stage is a second or additional system
that will provide extra heating or cooling. When
a 2nd stage is operating the display will show
the number 2 by the heat/cool icons.
A temperature differential (default value is 2.0 °F or 1.0 °C) and time
delay (default value 20 minutes) control the 2nd stage cycle.
Operation of the 2nd stage begins when:
• The room temperature changes from the setpoint by the sum of the
1st and 2nd stage differential settings.
• The first stage has been on for the specified delay time, but the
heating/cooling demand has not yet been met.

Energy Efficient Recovery

With Energy Efficient Recovery, the thermostat "Looks Ahead" to the
next event and attempts to reach the next setpoint at the exact time of
the event. If you have two stages, the thermostat will use only the first
stage during this period. This is more efficient than waiting until the
next event and then turning on both first and second stages.

Backlit Display

This thermostat is equipped with a backlight to make viewing the display
easy. Press the
turn off after 10 seconds of inactivity. If the thermostat is wired to have
the backlight stay on all the time the night light can be turned on/off in
the settings menu.
