)
The 0 - 10 V output signal A2 can, e.g., be used for triggering a shutter or heating.
Setting Offset AnalogOut
The target value for this output is the target value (Setpoint) for the ventilation “ offset ”
setting.
Adjustment: range +/- 10,0 K relative to the active Setpoint.
Example for triggering a shutter servomotor:
At factory setting
“ 0,0 K ” = synchronous operation.
The analog output is factory set to increasing activation during increasing temperature.
Reprogramming to
“ Heating function ” , i.e., increasing modulation during decreasing
temperature is possible ( IO Setup).
