7.3.2 On/off control
Set F4 to 0 = OFF and P13 = Differential gap, P14 = Minimum activation time and P15 = Mi-
nimum deactivation time.
The controller issues a control signal OPEN (+) and CLOSE (-). The switching characteristic is
determined by selecting the differential gap. Unnecessary cycles can be avoided by specif-
ying the minimum activation and deactivation time.
7.4 Limitation of the flow temperature
Set P3 = Minimum flow temperature and P4 = Maximum flow temperature
You can enter a maximum and minimum flow set point to limit the flow temperature.
The parameter P3 limits the flow temperature to a minimum and can be set between 0 and
130 °C. The default setting is 30.0 °C.
The parameter P4 limits the flow temperature to a maximum and can be set between 20 and
130 °C. The default setting is 80.0 °C.
In the following example, the maximum flow temperature is limited to 90 °C in weather-com-
pensated control, while the minimum flow temperature is limited to 45 °C. When the flow
temperature exceeds or fall belows the limit value, just the limit value is used for the control,
i.e. the outdoor temperatue in these ranges has no effect on the control.
