Braeburn 2200 - Manual (Page 7)

Symptom: Thermostat turns heating or cooling system on too often or not
often enough.
Potential Solution: Increase or decrease first stage temperature differential
setting 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 8.
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
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 5. If AC power is present, call a
professional service technician to verify thermostat and system performance.
Symptom: HI is shown in the thermostat
display where the room temperature is
normally displayed.
Potential Solutions: The temperature
sensed by the thermostat is higher than the
99˚ F (37˚ C) upper limit of the thermostat’s
display range. The display will return to normal after the sensed temperature
lowers within the 40˚ to 99˚ F (5˚ 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 exceptionally
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 where the room temperature is
normally displayed.
Potential Solutions: The temperature
sensed by the thermostat is lower than the
40˚ F (5˚ 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 (5˚ 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 to allow proper
heating control once installed.

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.
Compressor protection feature may be in effect due to compressor short cycle
conditions. See section 7.
Heating or cooling system may be malfunctioning. Call a professional service
technician immediately to verify system operation.
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 10.
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 5.
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 period expires the system should start
within several seconds.
Thermostat program has been temporarily overridden and program indicator
is flashing in the display. Press the
HOLD button twice to return the thermostat to
normal program operation or wait until next set point and the temporary override
will expire.
Thermostat program is in Extended Hold (Vacation) Mode and
HOLD is showing in
display. Press HOLD button to release permanent hold and return the thermostat to
normal program operation.
