Please note
Risk of damage to building
through overheating screed at
high flow temperatures.
Prevent high flow temperatures
through a temperature limiter as
maximum limiter for underfloor
heating systems.
Note
Observe the specifications of
EN 1264-4. The report to be provided by
the heating contractor must contain the
following heat-up details:
■ Heat-up data with respective flow tem-
peratures
■ Max. flow temperature achieved
■ Operating condition and outside tem-
perature during handover
Control settings, hydraulics
This function must be set to "NO" if the
heat pump is not ready for operation
