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.)
