Operating instructions Time Programing Overview The following instructions describe how to set the clock and how to program the time programs of the TCY-MZ for daily, weekly repeated action/function. These operating instructions apply to devices that support time schedules that is devices with an integrated real-time clock.
Up to 8 time and weekday programs can be programmed (Pr01 to Pr08). Time schedules can change the setpoint of the controller. Devices with a "D" addition (e.g. TCY-MZ-D) have a real-time clock with a maintenance-free power backup. A flashing clock time “00:00” indicates that the time has not been set or that the device has been without power for more than 48 hours.
