5.7 Record - Activation of screed function
4 213 787 / 01
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.
Settings in the TopTronic
®
E control module
Can only be set in the corresponding user level.
Settings under Start screen > Main menu > Service > H­GEN >
Heating circuit > Heating circuit 1, 2, 3* > Screen > 04­060 to
04­064 .
* If there are several heating circuits, a separate screed function must be assigned to each
heating circuit.

Various settings can be made as
well. Prioritisation of the screed func-
tion means the settings are only ac-
tive at the end of the function.
2 Information remaining run time
Request of the active function phase,
the ACT temperature as well as the
remaining run time.
Logging
Please cut out the log and attach it to the controller during active screed function.
