Advanced Heat Pump Features
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.
Setting the Calendar
This Comfort Control is designed to automatically keep current
time and day in memory for up to ten years, under normal use,
