The drying function is activated by changing the setting
STOP
to
START
after
Temperature re
-
duction
. The course of the drying process can be monitored in the information level over the
icon of flow temperature display ( ) of the associated heating circuit:
Temperature build-up phase
Temperature maintaining phase
Temperature reducing phase
The drying process has been successfully completed when the additional icon in the flow
temperature display goes out after the last phase without the operating fault appearing.
STOP
on the display indicates that there has been a deviation of flow temperature of more
than 5 °C for longer than 30 minutes. The function is canceled by the controller in such
cases. While
STOP
appears on the display, the controller keeps the flow temperature con
-
stant at 25 °C.
A power failure while the drying function is active or when
STOP
appears on the display au-
tomatically leads to the drying function restarting.
In systems in which the drying function had to be interrupted due to DHW heating (e.g.
Anl 2.1, 4.1), storage tank charging does not occur while the drying function is active, pro-
vided it is not used for frost protection of the storage tank.
Note!
The function block parameter can only be accessed when the function has started by deacti-
vating the function block and activating it again.
