cont.
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 this light is active, 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: 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 9.
Symptom: Thermostat turns heating or cooling system on too often or not
often enough.
Potential Solution: Increase or decrease temperature differential settings as
appropriate to provide the desired performance level. See Section 4.
Symptom: Low battery indicator is shown in thermostat display.
Potential Solution: Replace batteries immediately to maintain proper system
operation. See Section 7.
Symptom: OFF is shown in thermostat display and heating or cooling system will
not start.
Potential Solution: This indicates that the system is turned off at the thermostat.
The thermostat must be in
HEAT or COOL modes of operation to control the heating
or cooling system. Move the system selector switch to the HEAT or COOL position.
Symptom: Thermostat display is blank.
Potential Solution: It is possible that AC power is not present at the thermostat
and/or the batteries are drained. Check fuse, circuit breaker and thermostat
wiring as appropriate to verify AC power is available. Replace batteries before
reprogramming thermostat. See Section 7. If AC power is present, call a
professional service technician to verify thermostat and system performance.
Symptom: The room is too warm or too cold.
Potential Solution: See Section 5. Review current set point and change
as necessary.
Symptom: Fan runs intermittently or when system is off.
Potential Solution: Fan switch is in Circulate ( ) Mode.
Symptom: HI is shown in the thermostat display.
Potential Solution: The temperature sensed by the thermostat is higher than the
99˚ F (37˚ C) upper limit of the thermostats display range. The display will return to
normal after the sensed temperature lowers within the 40˚ to 99˚ F (4˚ to 37˚ C)
display range. Turn on the cooling system or use other methods to lower the
temperature accordingly.
This condition could occur from the system being turned off during an exception-
ally warm period or upon installation when the thermostat has been stored for a
long period of time in a warm vehicle or location prior to being installed.
Symptom: LO is shown in the thermostat display.
Potential Solution: The temperature sensed by the thermostat is lower than the
40˚ F (4˚ C) lower limit of the thermostat’s display range. The display will return to
normal after the sensed temperature rises within the 40˚ to 99˚ F (4˚ to 37˚ C)
display range. Turn on the heating system to raise the temperature as needed for
comfort within the room.
This condition could occur from the system being turned off during a cold weather
period or upon installation when the thermostat has been stored for a long period
of time in a cold vehicle or location prior to being installed. The thermostat should
be allowed to warm up prior to installation in order to provide proper heating
control once installed.

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.

Battery Replacement

Replacing the Batteries
1. Open the thermostat cover and locate the battery compartment door.
2. Remove the two "AA" alkaline batteries located in the battery compartment.
3. Install two new "AA" alkaline batteries into battery compartment. Make sure to
match the positive (+) ends of the batteries with the positive (+) terminals
located in the battery compartment.
4. Close battery compartment and verify that the low battery indicator does not
appear in the display.
Troubleshooting

Symptom: Thermostat does not turn on heating or cooling system.
Potential Solution: 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.
Compressor protection feature may be in effect due to compressor short cycle
conditions. See Section 6.
Heating or cooling system may be malfunctioning. Call a professional service
technician immediately to verify system operation.
