30 Revision history of LMV37.4 17.12.2018
Software version V02.90
Optimization: Indication of errors on the parameter and info / service menu
Optimization: Rectification of eBus error telegrams, correction of manufacturer's
code for safety temperature limiter, extension of service data query PB:03h SB:10h
in order to read out / query the meter readings for the second fuel; the current fuel is
output in query PB:05h SB:09h
Optimization: Curve setting invalid (OFF UPr) upon change to cold settings
Optimization: Setting of minimum / maximum output via the parameterized
output
Optimization: Shorter startup time with valve proving (prepurge or postpurge time
simultaneously with valve proving)
New function: Loss-of-flame test (TÜV test), forced shutdown of fuel valves
Extension: Oil pressure switch-min active from phase 38 or safety time (phase 40)
Extension: Setting of dead band zone for load controller contacts, analog input and
building automation system output
Extension: POC for firing on oil (alternative to pressure switch-max)
New function: Valve proving via pressure switch-min
New function: Abortion of postpurging (see postpurge time, extraneous light test in
phase 78)
New function: Evaluation of load controller contacts for multistage operation (normal
/ interchanged)
New fuel trains LoGp, Lo-2V, LoGp-2V
New operating modes (e.g. without actuator)
New function: Backup / restore via AZL2 (only with new software version AZL2)
Software version V03.00
Optimization: Maximum time of safety phase reduced from 28 to 27 seconds.
