The PCZ-528.3 clock controller can operate in one of the three
modes of operation:
»
Automatic mode
Operation in automatic mode involves the automatic proces-
sing of all programs stored in the memory of the controller.
»
Semi-automatic mode
Semi-automatic mode means a temporary interruption of
operation in automatic mode and the possibility of manually
switching the relay contact to the opposite position. The timer
operation in semi-automatic mode is indicated by blinking of
the timer dial on the controller display. Operation in semi-au-
tomatic mode is stopped when the next operating program
is activated, after which the controller returns to automatic
mode.
»
Manual mode
In manual mode, the list of programs stored in the memory
of the controller is ignored and switching on/off is performed
manually by the user.
In manual mode, the state of the relay can be changed by brie-
fly pressing the +/– button on the front of the controller or an
external button connected to the timer control input.
