You can set up to seven period times with different
calculated flow temperatures. If less than seven periods
are to be used, set the remaining period times to 0 days.
Mark the active window to activate the underfloor drying
function. A counter at the bottom shows the number of
days the function has been active. The function counts
degree minutes as during normal heating operation but
for the supply temperatures that are set for the respect-
ive period.
NOTE
During under floor drying, the heating medium
pump in 100% runs, regardless of the setting
in menu 5.1.10.
TIP
If operating mode "add. heat only" is to be used,
select it in menu 4.2.
For a more even flow temperature the addition
can be started earlier by setting "start for addi-
tion" in menus 4.9.2 to -80. When set under
floor drying periods have stopped, reset the
menus 4.2 and 4.9.2 as per previous settings.
