18SYSTEM MALFUNCTION SCREENOUTSIDE: 84_ | FAN: AUTO71_HVAC SERVICE1--- 800--- 555--- 1212SYSTEM MALFUNCTIONCALL TECHNICIAONA07036Fig. 34 -- System Malfunction ScreenFan CoilThe code number represents flash code on circuit board of fan coil.Certain faults will generate a system malfunction message on themain screen. When this occurs, a technician should proceed to theLast 10 System Events screen in the Service Menu to determinewhich fault has caused the message.Below is a list of which faults will result in a System Malfunctionevent:Code 37 -- Heater output sensed On when not energizedCode 41 -- Blower Motor Fault (ventilator, humidifier,dehumidifier, outdoor unit will be turned off)Code 44 -- Motor Communication Fault (ventilator, humidifier,dehumidifier, outdoor unit will be turned off)Code 45 -- Control failureFurnaceThe code number represents flash code on circuit board of furnace.Code 13 -- Limit Circuit LockoutCode 14 -- Ignition LockoutCode 15 -- Blower Motor Lockout (ventilator, humidifier,dehumidifier, outdoor unit will be turned off)Code 21 -- Gas Heating LockoutCode 22 -- Abnormal Flame Proving SignalCode 23 -- Pressure Switch Did Not OpenCode 24 -- Secondary Voltage Fuse OpenCode 33 -- Limit Circuit Fault AND high heat only is activeCode 41 -- Blower Motor Fault (cooling mode only) (ventilator,humidifier, dehumidifier, outdoor unit will be turned off)Code 45 -- Control Circuitry LockoutNOTE: For codes 13, 14 and 21, the system will use heat pumpheating exclusively if available. When the error code is cleared ordisappears, furnace heating will resume if still requested.Service Tool ModeThe --V model of user interface software version 21 can be used asa service tool on any Infinity system. Attach the --V model userinterface anywhere on the ABCD wiring (e.g. at the indoor oroutdoor unit). When the user interface powers up, it will ask theuser if they wish to enter service mode. Selecting “Yes” will allowthe --V model user interface to take over as the system controller,putting the regular system user interface to sleep. The screen on theregular user interface will display “IN SERVICE MODE”. The --Vmodel user interface will then learn all equipment and function asthe system controller. While in service mode, the --V model userinterface will not transfer any settings or information to or from theregular user interface----it only takes over control of the system.After removing the --V model user interface from the ABCDwiring, the regular user interface will take over the system after twominutes.Outdoor UnitThe code number represents flash code on circuit board of outdoorunit.Code 25 -- Invalid model plugCode 45 -- Control FailureCode 47 -- No 230V at unitCode 48 -- Loss of inverter communicationsCode 69 -- Inverter internal faultCode 73 -- Contactor shortedCode 74 -- No high voltage at compressorCode 76 -- Low stage didn’t start three timesCode 78 -- High stage didn’t start three timesCode 81 -- Thermal lockout in low stage -- 4 hrs.Code 82 -- Thermal lockout in high stage -- 4 hrs.Code 83 -- Low Pressure Lockout -- 4 hrs.Code 84 -- High Pressure Lockout -- 4 hrs.Code 85 -- Low contactor openCode 86 -- Low contactor shortedCode 87 -- High contactor openCode 88 -- Inverter Temp Lockout or High Contactor ShortedCode 96 -- VDC under voltage lockoutCode 97-- VDC over voltage lockoutCode 99 -- High torque lockoutUser InterfaceS Temp sensor failed, loss of communication with smart sensor,smart sensor fault. “NO SENSOR DATA” shownS Indoor unit communication faultS Outdoor unit communication faultS Packaged product communication faultS NIM communication faultS SAM communication faultS Possible Frozen CoilS High Room Temp Alert, when 100_F exists for at least 10minutes, and removed when less than or equal to 98_F existsS Low Room Temp Alert, when 38_F exists for at least 10minutes, and removed when greater than or equal to 40_F existsS High Humidity Alert, when 80% Rh exists for 30 minutes, andremoved when less than or equal to 78% Rh existsThe user can press the right side button to dismiss the notice. Theregular run mode screen will then appear except “SYSTEMMALFUNCTION” will appear in place of the day/time. If the errorhas not disappeared within 24 hours, the above display will return.If the error code disappears, “SYSTEM MALFUNCTION” willdisappear and the day/time will reappear.Copyright 2011 Carrier Corp.
