NOTICE
The activation of the screed function must only be made by a specialist trained by Hoval or by Hoval cus-
tomer service.
Description of function
The control module of the TopTronic
®
E contains a functional sequence used for drying out screed fl oors. To start the
screed drying, it is necessary for the individual functions to be set accordingly.

NOTICE
The graphic/table shows the factory settings. The time profi le and the maximum fl ow temperature must be
discussed with the screed layer, otherwise there could be damage to the screen – and in particular, cracks.
REACTION
screed function
• Start/stop: Switch parameter 04-060 ON (1) or OFF (0)
• Power failure in heating-up phase: program restart
• Failure in the steady-state phase: Retain maximum temperature and add the failure time to the steady-state phase
•
Power failure in the cooling off phase: Measurement of actual fl ow value and continue cooling until start value reached
• Program end: Previous basic program active again
Additional info:
When the screed function starts, the heating circuit pump is switched on and the screed function starts after 1 minutes.
The FL set value must be reached in each case so the controller continuously increases the fl ow temperature according
to the set ramp. With HC parameter “04-069 Maximum temperature diff erence ramp increase (factory setting: 10 K)”
it possible to set by how much the FL set value calculation is allowed to increase without the actual value reaching the
set value.
