The pressure setpoint for actual control is determined from a conversion table contained in the software.
Conversion of t

4.3.11 Second setpoint – Setpoint increase/decrease
A second characteristic can be programmed for low-pressure control and can be activated by the internal week
timer or via a digital input of the controller. Setpoint increase/decrease allows better matching to night and week
end operation. Setpoint toggle is performed for the following values:
S
Target temperature(s)
S
Neutral zone
S
Control constant
The polarity of digital input signals can be programmed (low or high active).
