Options
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either

12.34.60 Additional cooling stage – Control direction of control valve
Options
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either
"Cooling with additional stage" or "Heating and cooling with additional stages", only
available when the "Extended settings" parameter under "Control of cooling additional
stage" is set on "Yes".
The mode of the control value can be used to adapt the control value to de-energized
