Risk of damage to building
through overheating screed at
high flow temperatures.
Prevent high flow temperatures
through a temperature limiter
as maximum limiter for under-
floor heating systems.

EN 1264-4. The report to be provided
by the heating contractor must con-
tain the following heat-up details:
Heat-up data with respective flow
temperatures
Max. flow temperature achieved
Operating condition and outside
