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.
Three Stage Systems
A 3rd stage is a third or additional system that will
provide extra heating in heat pump applications.
When a 3rd stage is operating the display will
show the number 2 and E by the heat icon.
A time delay (default value 20 minutes) controls the 3rd stage cycle.
This time delay starts when the second stage turns on.
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 button to activate the backlight. The backlight will
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.
Overriding the Schedule Settings
When the thermostat has been programmed, the settings and the
schedule are saved. The thermostat will run to the schedule unless an
override is entered.
Two methods of override are available.
Permanent Override
Press START/STOP SCHEDULE until the word SCHEDULE is not shown
on the display. A Permanent Override allows the thermostat to maintain
a setpoint indefinitely. To switch between Schedule and Permanent
Override, press START/STOP SCHEDULE button. Press
change the setpoint. The heat or cool mode should be selected.
