For operation as controller (starting from 2.01 ): switch over “Setpoint 1” / “external Setpoint ”
Possible only for operation with one control circuit!

9.5.2.9 Automatic control / speed manual Function
| 7D | (mode 2.01 )
Possible only for operation with one control circuit!
Switch over between automatic control to set target value (depending on the activation: “Setpoint1”,
“Setpoint2”) and the default for “manual operation” set at the device.
If for Analog In 2 “E2 function” is programmed to
| 2E | switch over between “Setpoint1” or “Setpoint2”
and external manual operation. With activated manual mode the display constantly changes between
“actual value” and value for “manual mode”.

9.5.2.10 Reverse action of control function (
2.01 ), Function | 8D |
Switchover between: Increasing modulation during increasing actual-value and increasing modulation
during sinking actual-value.
The factory presets for the “Control function” are dependent on the selected mode of operation (
Controller Setup - reverse operation of the control function).
When switching over via a digital input, the device works with the opposite function as set there.
The inversion of the control function influences both circuits in operation with two control circuits.
