4B. Compressor Lockout

Installation > Advanced HVAC Options > Compressor Lockout

This feature is intended to help protect the compressor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can verify if the lockout feature is already present in their system.

Options for this menu item include:

•OFF: (Default) No compressor wait time; assumes lockout feature is already present.

•ON: Waits five minutes before turning on the compressor after a power loss or during cooling/heating cycles. Protects the compressor from short cycling.

4C. Comfort Alert Active Protection

Installation > Advanced HVAC Options > Comfort Alert

The thermostat is compatible with air conditioners and heat pumps that feature Copeland Comfort Alert™ protocol. When the thermostat is connected to comfort alert enabled equipment and active protection is selected, the thermostat will turn off the compressor if a condition exists that may potentially damage the system.

If the thermostat is connected to Comfort Alert™ enabled HVAC equipment, it is recommended that you turn on the Comfort Alert feature in the thermostat. When the feature is turned on and a condition exists that may potentially damage your air conditioner or heat pump, the thermostat will automatically shut off the compressor and display “Call For Service” on the home screen. When you see this message, it is recommended that you call a qualified contractor to schedule a repair appointment.
