5.2Fixed set point control

During the times-of-use, the flow temperature can be controlled according to a fixed set point. Outside the times-of-use, this set point is reduced by the Set-back difference. Both Minimum flow temperature and Maximum flow temperature parameters are set to identical values.

Parameters	WE	WE*	Range of values
Max. flow temperature	90 °C	50 °C	20 to 130 °C
Min. flow temperature	20 °C	20 °C	20 to 130 °C

* Default setting applies to system Anl 9, underfloor heating

5.3Underfloor heating

The system Anl 9 is designed for radiator heating in conjunction with an underfloor heating cir- cuit.

The maximum flow temperature of the radiator circuit is only available to the underfloor heating circuit. If the radiator circuit is in rated operation, its flow temperature is only reduced so far to ensure that the flow temperature of the underfloor heating circuit does not fall below the temper- ature according to the heating characteristic for the control circuit RK2. If the radiator circuit is switched off due to the outside temperature, the controller still continues to regulate a flow tem- perature according to the heating characteristic for the control circuit RK1 at the flow sensor VF1 despite of the deactivated circulation pump UP1.

Functions such as Optimization, Adaptation or Flash adaptation are only available for the ra- diator circuit after regulating the temperature according to the room temperature. A connected remote operation also only has an influence on the operation of the radiator circuit.

The summer mode causes both heating circuits to be switched off. The OT deactivation value in rated operation parameter relates to both heating circuits, whereas the OT deactivation value in reduced operation parameter only effects the radiator circuit.
