Level:
In addition to the gradient, the level of the heating characteristic can be lowered or raised by
±
30°C using the parameter P2. This parameter provides you with a further option to adapt
the heating to your individual requirements. The parameter P2 can be accessed on the instal-
lation level and has the default setting of 0 °C.
The right graph in Fig. 4 shows how the level displacement by -19°C effects a heating char-
acteristic with a gradient of 2.2.
7.1.2 Fixed set point control
Set the function block F1 to 0 = OFF.
A sensor VS for the flow temperature is required.
When the fixed set point control is selected, the set point of the flow temperature appears on
the left-hand side of the display and the actual value of the flow temperature appears on the
right-hand side.
The default set point for rated operation (time-of-use) is 65 °C and for reduced operation
(time of non-use) 50 °C.
Note:
The current flow temperature set point can be briefly changed on the display level. It
remains activated until the next time-of-use or time of non-use comes into effect.
See chapter 5.1 on setting.
