: Signal output 0 - 10 V
The 0 - 10 V output signal can, e.g., be used for triggering a shutter or heating.
Offset AnalogOut
Offset AnalogOut
The target value for this output is the target value (Setpoint) for the ventilation

setting.
Adjustment: range +/- 10 K relative to the active Setpoint.
Example for triggering a shutter servomotor:
At factory setting
“
0 K
”
= synchronous operation.
The analog output is factory set to increasing activation during increasing temperature.
Reprogramming to

, i.e., increasing modulation during decreasing
temperature is possible (
