Programmable cotrol timer – weekly PCZ-531A10

Functioning
The timer sets the brightness of the output circuit to the preset level (range 0-100%) on the preprogrammed hours in daily, weekly, business days (Mo.-Fr.) or weekend (Sa.-Su.) cycles. It is possible to program up to 480 indepen-dent program steps. The controller is equipped with a local input allowing remote control of the controller with any monostable button and with an auxiliary relay that activates when the output is switched on (set brightness level higher than zero).
