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.
4B. Compressor Lockout
Installation > Advanced HVAC Options > Compressor Lockout
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.
4C. Comfort Alert Active Protection

to exit to the home screen.
If your system does not have a G terminal connection,
proceed to Heating System.
Check fan operation
Menu > Settings > Fan
1. Press the MENU button and select FAN ON in the thermostat
display. The blower should begin to operate. Place your hand by
a vent to confirm blower is running.
2. Select FAN AUTO to return to standard setting. The blower will
only cycle with call for cool or heat.
Check the cooling system
1. Press the Heating / Cooling Mode key one or more times to
select COOL.
2. Press the to adjust thermostat setting 1° below room
temperature. The blower should come on immediately on
high speed, followed by cold air circulation.
14

Check the heating system
1. Press Heating / Cooling Mode key one or more times to select
HEAT mode. If the auxiliary heating system has a standing pilot,
be sure to light it.
2. Press the to adjust thermostat setting to 1° above room
temperature. The heating system should begin to operate.
NOTE: If the system is configured as a heat pump and compressor lockout is
set to ON, the thermostat will not call for heat until after the 5 minute safety
time period. After the 5 minutes expire the thermostat will call for heat.
3. If the system is a multi-stage cooling system, adjust the
temperature setting to at least 3° below room temperature.
The second stage cooling should begin to operate.
4. Press the to adjust the temperature setting above room
temperature. The cooling system should stop operating.
NOTE: If compressor lockout is set to ON, the thermostat will not call for cool
until after the 5 minute safety time period and will display the message A/C
return < 5 min. After the 5 minutes expire the thermostat will call for cool.
3. If the system is a multi-stage heating system, adjust the
temperature setting to at least 3° above room temperature. If the

the second stage of the heating should begin to operate. Within a
very short period, the Back Up heat should begin to run and Back
Up Heat will be displayed.
4. Press the to adjust the thermostat below room temperature.
The heating system should stop operating.
15

Check the back-up heating system
(heat pump systems only):
The Back Up Heat bypasses the heat pump to use the heat source
wired to E & W2 terminals of the thermostat. Back Up is typically
used when compressor operation is not desired, the user prefers to
utilize the back-up heat only, or the compressor is not able to satisfy
the demand for heat to the users desire.
1. Press Heating / Cooling Mode key one or more times to select
Back Up Heat mode. If the auxiliary heating system has a
standing pilot, be sure to light it.
2. Press the to adjust thermostat setting to 1° above room
