Advanced Heat Pump Features (Select Models)
If you have a heat pump heating system, your comfort control can use some special features when
used with an Outdoor Temperature Sensor, such as compressor and/or backup heat lockout based
on outside temperature. For example, if your backup heat does not turn on above a designated
outside temperature, your system uses an advanced heat pump feature.

years, under normal use, once the calendar is set. There are two ways to set the calendar for this
comfort control:
SETTING CALENDAR AFTER COMFORT CONTROL IS ALREADY FUNCTIONING
See steps 1 through 4, in the Advanced Settings section, to set year, month and day.
SETTING CALENDAR WHEN COMFORT CONTROL IS FIRST POWERED
When this comfort control is first powered, the display is ready to set the calendar.
