Braeburn 51** series thermostat troubleshooting

SYMPTOMPOTENTIAL SOLUTION
Thermostat does not turn on heating or cooling system.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. Compressor protection features may be in effect due to compressor short cyde conditions, power outages or rolling blackouts.
Thermostat turns on heating instead of cooling, or cooling instead of heating.Check thermostat wiring to make sure that the heating and cooling stages are connected to the correct terminals on the wiring terminal block.
Thermostat will not follow program setpoints.Check current time of day, day of week program settings. Make sure to verify AM/PM indicator is accurately displaying desired time settings.
Thermostat turns heating or cooling system on too often or not often enough.Increase or decrease first stage temperature differential setting as appropriate to provide the desired performance level.
Thermostat turns on second (auxiliary) stage of heating or cooling too quickly or not quickly enough.Increase or decrease second (auxiliary) stage temperature differential setting as appropriate to provide the desired performance level.
OFF is shown in termostat display and leating or cooling system will not startThis 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 several seconds.
Low battery indicator is shown in thermostat display.Replace batteries immediately to maintain proper system operation.
Thermostat display is blank.It is possible that AC power is not present at the thermostat and the back-up batteries are fully discharged. Check fuse, circuit breaker and thermostat wiring as appropriate to verify AC power is available. Replace back-up batteries before reprogramming thermostat to make sure you have back-up power.
Thermostat will not allow me to program a setpoint temperature higher than 90° F(32° C).This is above the normal thermostat temperature setting range of 45° to 90° F(7° to 32° C).
Thermostat will not allow me to program a setpoint temperature lower than 45° F (7° C).This is below the normal thermostat temperature setting range of 45° to 90° F (7° to 32° C).
Thermostat will not allow me to change the setpointThe Keypad is locked. Press both the A and V key together at the same time for one second to unlock
The room is too warm or too cold.
HI is shown in the thermostat display where the room temperature normally displayedThe 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 (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. The thermostat is equipped with a mechanical high temperature safety switch that will turn off the thermostat should the temperature exceed 99° F (37° C).
LO is shown in the thermostat display where the room temperature normally displayedThe temperature sensed by the thermostat is lower than the 40° F. (5° C) lower limit of the thermostats 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. If the temperature in the controlled space seems to be normal, wait for the thermostat to acclimate to the correct room temperature. If the room seems to be colder than usual, 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.
