Automatic switch back from manual to auto operation after programmable time

The duration of the extended day/ night operation can be limited with the parameters SYS-01/ SYS-02.


When the user switches the wall module button to the ‘DAY’ position, the "ManSwCond" output is set to ‘1’ , indicating the extended day operation and the day extension timer starts. When the extended day timer exceeds the value of SYS-01, the "ManSwCond" output switches back to auto mode.

To restart the day extension timer, the switch must be set back to auto and then to day again.


When the user switches the wall module button to the ‘NIGHT’ position, the "ManSwCond" output is set to ‘0’ , indicating the extended night operation and the night extension timer starts. When the extended night timer exceeds the value of SYS-02, the "ManSwCond" output switches back to auto mode.

To restart the night extension timer, the switch must be set back to auto and then to night again.


Note: To disable the automatic switch back from manual day or hight operation to automatic operation set the SYS-01/ SYS-02 to 0.
