45 High T
e boiler detects a sudden, unexpected increase in the ΔT between
the ow probe and the system return probe.
e power of the burner is limited to pre-
vent damage to the condensation module
and once the right ΔT is restored, the boiler
resumes regular operation. Make sure there
is water circulating in the boiler, that the
pump is congured according to system
requirements and that the return probe
works properly. (1) (2)
