Special operating programs
"Screed drying"
This function is switched on by your contractor. Your
screed is dried in line with a set time program (tem-
perature/time profile) suitable for the relevant build-
ing materials. Your settings for central heating have
no effect on the duration of screed drying (max.
32 days). The system no longer provides DHW heat-
ing. The function can be altered or switched off by
your contractor.
"External hook-up" or "External blocking"
The operating program set at the heat generator has
been switched over by an external switching device,
e.g. EM-EA1 extension (DIO electronics module).
The operating program cannot be changed via the
heat generator control unit for as long as the external
hook-up is enabled.
"Holiday program": See page 32.
For "Holidays at home": See page 30.
Note
The special operating programs are shown on the dis-
play in alternation with the heat generator flow temper-
ature.
In the main menu, you can check the set operating
program under "Information": See page.
