compensation of the pressure setpoint.

The output signal will increase when the pressure signal falls below the setpoint value.
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:
DMD
DTL-series
DTK-series
TTK-series
Pressure ranges up to 500 kPa kan be set.
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.
Note: This input must always be wired since it controls the starting and stopping of normal
control.
