Functions of the heating circuit

5.8Flash adaptation

The function is only active in automatic mode ( ).

Direct reactions to deviations in room temperature can be achieved using the function block set- ting: FB2 = ON. A gradient characteristic (FB19 = OFF) must be configured.

Flash adaptation counteracts room temperature deviations by increasing or decreasing the level of the heating characteristic by up to 5 °C. The corrections are made after 10 minutes by 1 °C. The corrected value is indicated in the parameter level under the datapoint for Level, flow.

Note!

Cooling loads, such as drafts or open windows, affect the control process!

Rooms may be temporarily overheated when the cooling load has been eliminated!

5.9Adaptation

The function is only active in automatic mode ( ).

The controller is capable of automatically adapting the heating characteristic to the building characteristics, provided a gradient characteristic has been set (FB19 = OFF). The reference room, where the room sensor is located, represents the entire building and is monitored to en- sure that the Room set point is maintained. When the mean measured room temperature in rated operation deviates from the adjusted set point, the heating characteristic is modified ac- cordingly for the following time-of-use. The corrected value is displayed in the parameter level under Gradient, flow.

Room set point	20 °C	0 to 40 °C
