﻿The operating hours counter can either be configured as a second counter or alternatively as an hour counter.

*Second counter*: The actuator adds up the determined switch-on time accurately to the second for a switched on dimming output. The totaled operating seconds are added in a 4-byte counter and stored permanently in the device. The current counter reading can be transmitted cyclically to the KNX by the "Value operating hours counter reading" communication object or when there is a change in an interval value in acc. with DPT 13.100.

*Hour counter*: The actuator adds up the determined switch-on time accurately to the minute for a switched on dimming output in full operating hours. The totalled operating hours are added in a 2-byte meter and stored permanently in the device. The current counter reading can be transmitted cyclically to the KNX by the "Value operating hours counter" communication object or when there is a change in an interval value in acc. with DPT 7.007.
