If another controller (addr. 20 ... 50) is connected to the direct heating circuit pump while the screed function is active, the screed function is cancelled automatically for the direct heating circuit pump.

All other heating circuits except for the direct heating circuit at addr. 10 are disabled. Frost protection monitoring, for example, does not occur for these heating circuits during this time.

Function The screed function is used exclusively for the required drying of newly applied screed on floor heating systems. The process is based on recommendations of the German Bundesverbandes Flächenheizungen (Federal Association for Surface Heating) concerning the heating of fresh floor covers (heating according to a mandatory temperature profile).

This is a special function that is not interrupted by any other control mode (including manual operation or emission measurement.

The screed function can be activated for mixed heating circuits and, in special cases (e.g. in conjunction with a condensing boiler) also for a direct heating circuit.

When the screed function is active, all weather-dependent control functions of the heating circuit concerned are switched off. The respective heating circuit operates independent of the control mode (switching times) as a constant temperature controller.

An active screed function can be deactivated at any time (parameter screed function = OFF).

On completion of the screed function, the heating circuit returns to operation according the current control mode setting.

The screed function consists of two steps:
