27:15 Cyclical heating time 15 min
Once the DHW cylinder with priori-
ty is heated up, the DHW cylinder
without priority is heated for a max-
imum duration equal to the set cy-
clical heating time.
28:3 Cyclical pause time 3 min.
After the selected cyclical heating
time for the DHW cylinder without
priority has expired, the rise in col-
lector temperature is captured dur-
ing the cyclical pause time.
