Special Features
Hybrid Heat (heat pump with a furnace system only)
This thermostat works with the Carrier Hybrid Heat systems offering
maximum comfort and economy by automatically controlling whether
your system delivers heating with the heat pump, with the furnace, or
with both options working together.
Service reminders
The thermostat tells you when it’s time to change or service the
UV light in the evaporator coil box connected to the furnace (if
equipped), humidifier pad (if equipped), and furnace filter. Each
reminder –
check UV light, check hum pad, check filter – will be
displayed near the center of the screen. (For important safety
reasons, ask your dealer to replace your UV light.)
To remove the reminder after you or your dealer have
replaced the indicated product, press and hold the
done
button for about three seconds. (Refer to page 28 for
additional details.)
