days), the mixer circuit is automatically regulated using
the set parameters. EN 1264 must be observed. The
report to be provided by the heating contractor must
contain the following details regarding heat-up:
■ Heat-up data with respective flow temperatures
■ Max. flow temperature achieved
■ Operating state and outside temperature during
handover
