Start
This function is used for time- and temperature-controlled screed drying in selectable heating
circuits.
The heating circuits can be selected in the Heating / Screed drying menu. At the end of this
menu, the function can triggered by using Start.
The controller will automatically change to the screed drying status menu. The current Phase
will be indicated on the display and the Remaining time will be indicated as a countdown
(dd:hh). During this process, the directional pad flashes green.
At the end of the menu, Cancel will be indicated instead of start. If Cancel is selected, screed
drying will be cancelled immediately.
At the beginning of the screed drying function, the heating circuits selected are put into operation
for the adjusted rise time with the starting temperature as the set flow temperature. Afterwards,
the set flow temperature increases in steps by the adjustable rise value for the duration of the
adjustable rise time until the holding temperature is reached. After the holding time has elapsed,
the set flow temperature is reduced in steps until the starting temperature is reached again.
If the set flow temperature is not reached within 24 hours or after the rise time respectively, or if it
is constantly exceeded, the screed drying function will be cancelled.
