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 limit thermostat, extension of service data interrogation PB:03h
SB:10h by the meter readings of the second fuel, PB:05h SB:09h shows the fuel
currently burnt
• 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: Pressure switch-min-oil active from phase 38 or safety time (phase 40)
Extension: Setting of dead band zone for load controller contacts, analog input and
BACS output
• Extension: POC for fired 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
