Operating instructions

■ The screed programme affects all ena-
bled heating circuits in parallel.
■ The selected "Screed program" is
continued after a power failure or after
the control unit has been switched off.
■ The selected operating programme
continues if the "Screed program"
has terminated in accordance with the
programme or, before its expiry, the
temperature/time profile "0" is selec-
ted.
■ The temperature/time profiles 7 to 12
regulate to the maximum flow temper-
ature.
■ If the time profile has a higher set flow
temperature, the set temperature is
limited by parameter "Maximum flow
temperature" (see page 109) for the
heating circuit.
■ The power consumption increases
when using an instantaneous heating
water heater (accessory) for drying
buildings.
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
