• Assure 208/230 volt and 24 volt power to blower and control board. • Check fuse F2U on control board • Check for possible short in 208/230 volt and 24 volt circuits. Repair as necessary. • Replace the control board. • Select the valid heater kit on thermostat • Valid dip switch selection (heater kit selection out of range of the unit configuration) • Set correct dip switches • Replace fuse • Check wiring to AUX alarm, heater kit, communication connection. • Replace the control board After recovering the system, E5 will still be displayed on the indoor PCB (about 30 seconds). BLOWN FUSE will still be displayed on the thermostat within 45 seconds. They will be cleared automatically. • Check water level in drain pan • Check alarm device. • Close Auxiliary terminals TB4 and TB5 if not used After recovering the system, EF will still be displayed on the indoor PCB (about 30 seconds). AUXILIARY CONTACTS OPEN will still be displayed on the thermostat within 45 seconds. They will be cleared automatically. • Populate shared data set using memory card. • Populate shared data set using memory card. • Replace circuit board • Rewrite data using the correct memory card • Check for obstruction on the fan/motor • Verify the input voltage at the motor • Check wiring or tighten wiring connections if needed • Replace circuit board or motor • Check wiring or tighten wiring connections if needed • Verify the input voltage at the motor • Replace circuit board or motor • Correct motor installation • Populate shared data set using memory card. • Check for obstruction on the fan/motor/ductwork, clean filters • Verify the input voltage at the motor • Check wiring • Replace motor
