Parameter Name
Manual Fire Rate U Not set 0-100%
Sets a manual fire rate for the burner. Settings from 20-100% will hold the burner at that fire rate during
operation. Settings from 0-19.9% will shut down the burner. A setting of ---- (undefined) sets the burner
for automatic mode.
Min Load Change
123:00 - 0%
123:01 - 1%
123:02 - 0%
0-100%
This serves as a dead band for load changes. If the requested change in fire rate is less than the setting of
this parameter, the actuators (and VSD) will not move. Settings of 5% or above may be counterproductive,
not permitting the boiler to closely match the load which may in turn cause hunting.
Index 00 = fire rate via Modbus (terminal X92)
Index 01 = fire rate via analog input (terminal X64)
Index 02 = not used.
TUV Test 0 -6-1
Activates the loss of flame test (TUV test). Setting this parameter to 1 starts the test. A value of 0 is
returned when the test is completed successfully. A negative value is returned if the test was unsuccessful.
See error code 150 for the cause of an unsuccessful test.
Mains Frequency 1 0-1
Sets the mains frequency:
0 = 50 Hz (Europe)
1 = 60 Hz (US)
AZL Brightness 100% 0-100% Sets the brightness of the backlight on the AZL display. A value of 100% is maximum brightness.
Password Timeout O 60 min 10-120 min
Sets the password timeout on the AZL display. If no buttons are pressed on the AZL display for longer than
this period of time, the AZL automatically logs out of the OEM (O) or service (S) level and reverts back to the
user (U) level.
Fuel Meter Scale 0 0-400
This sets the number of pulses per unit volume of gas or oil flow, for use with gas or oil meters having a
pulsed output.
Reset Fault History 0 -5-2
This parameter is used to delete the fault history from the user (U) level only. The service level fault history
cannot be deleted. To delete the user level fault history, change this parameter to 1, press Enter, then
change to 2, and press Enter again. This must be done within 6 seconds. If done successfully, this
parameter will return to 0. If done too slowly, this parameter will change to -1.
Load for TUV Not set 20-100% This sets the load for the loss of flame test (TUV test).
Modbus Activation 0 0-2
Sets the Modbus operating mode:
0 = off (inactive)
1 = on (active)
2 = not used
Modbus Watchdog 120 sec 0-7200 sec
If no communication occurs for this period of time, the LMV3 considers the Modbus to be unavailable and
will look for a fire rate command from another source (see parameter 942 for more details). A setting of 0
makes the timeout inactive and the LMV3 will wait for the Modbus communication to be available again.
Spare U 1 1-8 This parameter is not used.
Spare S 30 sec 10-60 sec This parameter is not used.
