Appendix A (conguration instructions)
Whentheadditionalreadingintheowtemperaturereadingdisappearsafterthelast
phase, this indicates that the drying process has been completed. Any power failure that oc-
curs while the function is running automatically restarts the drying function.
In systems in which the drying function had to be interrupted due to DHW heating (e.g. sys-
temAnl2.1,seepage16-12),storagetankchargingdoesnotoccurwhilethedryingfunc-
tion is active, provided it is not used for frost protection of the storage tank.
The function block parameters can only be accessed after after starting the function by deac-
tivating and activating the function block again.

16.2.4 Night set-back
Thenightset-back(=differenceoftheowtargettemperatureinratedandreducedmode)is
calculated in all heating circuits with a gradient characteristic as follows:
2x Heating characteristic gradient x (day room temperature – night room temperature)
16.2.4.1 OT activation value in rated operation
If a heating circuit is in reduced operation (automatic mode), this circuit is switched to rated
operation whenever the outdoor temperature falls below 'OT activation value in rated opera-
tion'. Reduced operation restarts after the outdoor temperature rises above the limit (plus
0.5°Chysteresis).
This function prevents the building from cooling down excessively outside the times-of-use
whenlowoutdoortemperaturesoccur.Thetransitiontowardsratedmodecanbecongured
to be variable depending on the outdoor temperature.
