5.5 Control mode 5, Pressure control with outdoor temperature
compensation of the pressure setpoint.
The output signal will increase when the pressure signal falls below the setpoint
value.
The AO1 inverted signal is received from AO2.
The setpoint value follows a settable pressure-to-outdoor temperature relation.
The pressure transmitter must have an output signal of 0...10 V DC, for example:
DSU
Pressure ranges of up to 2500 kPa kan be set.
The temperature range for outdoor temperature will be set to the low range for
this control mode, -
20…+60°C.
DI1, Start signal
Normal control will only be activated when this input is activated, closed. When
the start signal is deactivated the controller will set the output to 0.
This input must always be wired since it controls the starting and stopping of
normal control.
