ClimateTalk Message Description Possible Causes
• Assure 24 volt power to blower and control board.
• Check fuse F2U on control board
• Check for possible short in 115/230 volt and 24 volt circuits. Repair as necessary.
• Replace the control board.
• Populate shared data set using memory card.
• Replace circuit board
• Rewrite data using the correct memory card
• Check Indoor EEV coil connection (PCB and junction connector)
• Replace EEV coil
• Check the resistance value of EEV coil (refer service manual)
• Replace the control board
• Check the connection to liquid thermistor (PCB and junction connector)
• Check the resistance value of the thermistor (refer service manual)
• Replace thermistor
• Replace the control board
• Check the connection to gas thermistor (PCB and junction connector)
• Check the resistance value of the thermistor (refer service manual)
• Replace thermistor
• Replace the control board
• Check the connection to pressure sensor (PCB and junction connector)
• Check the output voltage of the pressure sensor (refer service manual)
• Replace pressure sensor
• Replace the control board
• Check for cased coil and other unit wiring.
• Replace the control board
• Check power supply to OD unit, Gas furnace or Modular blower
• Check for thermostat and indoor unit wiring
• Verify the input voltage at the ID unit and thermostat
After recovering the system with power supply, TSTAT ID NO COM will continue to be
displayed on the thermostat within 2 minutes.
The error code will be cleared automatically.
• Replace control board or thermostat
• Press "LEARN" button on PCB for more than 5 seconds to reestablish network
• Check for cased coil and other unit wiring.
• Replace the control board
• Check power supply to OD unit, Gas furnace or Modular blower
