System
parameter - Logical alarms display
The controller operates with 2 types of alarms: system and logical.
The system alarm is e.g. unconnected or damaged sensor, unassigned terminal of programmed
output, etc. These alarms are always displayed.
The logical alarm is caused by failure to meet any condition (logic), e.g. failure to reach the required
temperature behind the mixing valve within 1 hour or failure to reach the DHW temperature after
more than 3 hours, see alarm overview.
All alarms are displayed in the alarm history, see → Alarms menu according to the date and
time of occurrence for their later search and possible evaluation.
INFO - It is not recommended to activate the display of logical alarms in heating systems
for a boiler with manual stoking.
