6.11.27 Electronic limit thermostat
Line no. Operating line
2531 Cutout temp LT
The electronic limit thermostat monitors the current boiler temperature and switches the
burner off when the set limit temperature (Cutout temperature LT) is reached, or when
the boiler temperature can be no longer acquired (short-circuit or interruption of
sensor).
Note!
If an electronic safety limit thermostat (SLT) is used, Cutout temperature LT should
always be set to a level below TempBoilerMaxSLTSec [3639.1], thus preventing the
electronic safety limit thermostat from responding before the limit thermostat cuts out.
