Functions of the DHW circuit

Parameters	WE	Parameter level / Range of values
Day set point	20 °C	PA1, 2, 3 / 10 to 90 °C
Night set point	17 °C	PA1, 2, 3 / 10 to 90 °C
Sustained temperature	10 °C	PA1, 2, 3 / 10 to 90 °C

5.10 Flash adaptation

Direct reactions to deviations in room temperature can be achieved using the function block set- ting: Co1, 2, 3 -> Fb08 = ON.

Flash adaptation counteracts room temperature deviations by increasing or decreasing the flow temperature by up to 30 °C. The shift is displayed under Level in PA1, 2, 3 parameter levels; it cannot be altered. The set point correction over remote room panel is not possible.

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!

Room sensor RF1, 2, 3	OFF	Co1, 2, 3 -> Fb00 = ON
Flash adaptation	OFF	Co1, 2, 3 -> Fb08 = ON

5.11 Adaptation

The controller is capable of automatically adapting the heating characteristic to the building characteristics, provided a gradient characteristic has been set (Co1, 2, 3 -> Fb10 = OFF). The reference room, where the room sensor is located, represents the entire building and is moni- tored to ensure that the Day set point is maintained. When the mean measured room tempera- ture in rated operation deviates from the adjusted set point, the heating characteristic is modi- fied accordingly for the following time-of-use. The corrected value is displayed in PA1, 2, 3 pa- rameter levels under Gradient, flow.
