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
