Pressing the OK button when CLOCK is selected opens the following menu on the controller front panel.

To modify the date and time fields, simply select each field and apply the data modification method. The day of the week is recalculated automatically.

The "cal" line is used for correcting clock drift. To do this, note the controller clock drift by comparing it with a standard reference clock for a considerable period of time (several weeks or more) and record the drift detected in this line. For example, if the internal controller clock gains 12 seconds in 1 month, set –3s/wee. This correction will be corrupted if the controller is subject to prolonged power break or to signification temperature variations.
