This function requires the administrator password.
Use this function to Enable and Disable your Master’s control relays during circuit wiring or
maintenance. This function can also ‘hold back’ clocks to manually adjust for daylight savings in the
fall if you have chosen not to use Function 7 “Daylight Savings”.
[7]=Daylight Savings
This function requires the administrator password.
Your LTRx-512 knows the daylight savings time (DST) settings for over 75 countries. By using the 2-
