Additional Operation Features
This thermostat provides one type of cold weather compressor protection by
locking out the compressor stage (1st Stage) of heating for a period of time after
a power outage greater than 60 minutes. The lockout period is one hour less than
the outage time, up to a maximum of 12 hours. During that period of time, the
auxiliary heat stage will still be available to maintain the set point temperature.
The compressor lockout can be manually overridden at any time by moving the
system switch to the OFF position momentarily, then back to the heat position.
We still recommend using a separate outdoor thermostat for proper cold
weather protection.
AC Power Interrupt Warning
During a power loss, the thermostat will
display an outage warning. The system
clock will continue to run, and all settings
will be maintained until the outage period
is over. (This feature needs to be enabled -
see section 3)
Status Indicators
HEAT: This will turn on whenever the system
switch is in the HEAT mode. "HEAT" will
flash when the heating system is running.
COOL: This will turn on whenever the system
switch is in the cool mode. "COOL" will
flash when the cooling system is running.
EM HEAT: This will turn on whenever the
system switch is in the EMER (Emergency
Heat) mode.
AUX: This will turn on when the auxiliary
second stage of heating or cooling is
active. The auxiliary stage of heating is
usually the least economical stage of heat.
CHECK: Indicator will be displayed when
a malfunction occurs in the heat pump
system. When CHECK is displayed, call a
professional service technician to verify
system performance and switch the
system to Emergency Heat mode if
required to maintain room temperature.

Troubleshooting

Symptom: The word HEAT or COOL is flashing in the thermostat display.
Potential Solution: This indicates that the heating or cooling system is currently
running. When these systems are not running, HEAT or COOL will not flash.
Symptom: HEAT or COOL is flashing but the system is not running.
Potential Solution: The thermostat is telling the heating or cooling system to run,
but the system is not responding. You may need to call your local heating and air
conditioning contractor.
Symptom: Thermostat does not turn on heating or cooling system.
Potential Solutions: Check to see if OFF is shown in display. This indicates that
the system is turned off at the thermostat. Move the system selector switch to the
HEAT or COOL position. After the compressor short cycle protection 5-minute
period expires, the system should start within a minute's time.
Compressor protection features may be in effect due to compressor short cycle
conditions, power outages or rolling blackouts. See Compressor Protection and AC
Power Monitor on page 15 for a full explanation of this feature.
Heat pump may be malfunctioning. Review the CHECK status indicator in the
display. If the CHECK status indicator appears, call a professional service
technician to confirm heat pump operation and provide necessary service. If
heating is required you can slide the system switch to EMER setting which should
start the Emergency Heat source to provide heating until the heat pump can be
serviced.
Symptom: Thermostat turns on heating instead of cooling, or cooling instead
of heating.
Potential Solution: Check thermostat wiring to make sure that the heating and
cooling stages are connected to the correct terminals on the wiring terminal block
(see section 11).
Symptom: Fan runs intermittently or when system is off.
Potential Solution: This is normal operation when the fan switch is in circulate
( ) mode.
®
Symptom: Thermostat will not follow program set points.
Potential Solutions: Check current time of day, day of week program settings.
Make sure to verify AM/PM indicator is accurately displaying desired time
settings. See section 6. (Potential Solutions continued on page 18)
