Meaning for the LMV3 System Corrective Action
Note: Diagnostic codes are additive. If a diagnostic code appears that is not on this list, it is a combination of multiple diagnostic codes.
Any # Timeout building automation interface
1 Modbus timeout
2 Reserved
Any # TUV test
A fault occurred during the TUV test. See diagnostic codes for more
information.
1 (-1) Invalid phase
The TUV test can only be started in phase 60 (operation). Reset the fault.
When the LMV3 reaches phase 60, attempt to start the TUV test again.
2 (-2) TUV test default output too low
The TUV test default output (parameter 133/134) cannot be set lower than
the lower load limit (parameter 545/565). Either increase the TUV test
default output or decrease the lower load limit, then reset the fault.
3 (-3) TUV test default output too high
The TUV test default output (parameter 133/134) cannot be set higher
than the upper load limit (parameter 546/566). Either decrease the TUV
test default output or increase the upper load limit, then reset the fault.
4 (-4) Manual interruption No fault: The TUV test was aborted manually by the user.
5 (-5) TUV test timeout
There was no loss of flame after shutdown of the fuel valves. Check for
extraneous light or a faulty flame scanner, then reset the fault and start
the TUV test again.
Any # Trim function: Invalid analog value
1 Start prevention
2 Warning (trim function temporarily disabled)
Any # Trim function: Invalid curve setting of VSD / PWM blower
The following equations set the limits on the curve settings for the VSD /
PWM blower.
Fuel 0: Parameter 669:00 + parameter 547 ≤ curve point ≤ parameter
669:01 - parameter 548
Fuel 1: Parameter 669:00 + parameter 567 ≤ curve point ≤ parameter
1-9 Minimum value VSD curve invalid
A VSD curve point is below the permissible minimum value (diagnostic
code = point number, example: 1 = point P1)
21-29 Maximum value VSD curve invalid
A VSD curve point is above the permissible maximum value (diagnostic
code = point number, example: 21 = point P1)
41-49 Fuel 1: Minimum value VSD curve invalid
Fuel 1: A VSD curve point is below the permissible minimum value
(diagnostic code = point number, example: 41 = point P1)
61-69 Fuel 1: Maximum value VSD curve invalid
Fuel 1: A VSD curve point is above the permissible maximum value
(diagnostic code = point number, example: 61 = point P1)

Modbus communication has been interrupted for longer than the setting
of parameter 142. Re-establish communication, then reset the fault.
An invalid 4-20 mA signal was detected on input X64. Check the wiring to
terminal X64. Check the value of parameter 916. A value under -16%
indicates <4 mA is being detected, while a value over 26% indicates >20
mA is being detected.
