Ramsey Electronics URC1 manual For the master user to exclude devices from the user

To set timer1 on for 35 hours 12seconds, and off fore 10mS: *8101*00120035

Hook up some LEDs as shown with series resistors to the timer outputs, and then experiment a bit to see how this method works. Have patience as these codes take a little time to get used to.

For the master user to exclude devices from the user:

To exclude: *X[00-18]1

To include: *X[00-18]0

The access number is found on the chart with the pinouts of CON1. Since there is only 19 devices (0-18), any number over 18 is rejected and the command is aborted.

The URC1 replies with a short then long tone to indicate “A” for acknowledge.

Example to turn timer 2 off from the user: *9181

Where 9 is the control code, 18 is the device number, and 1 disables the device from the user changing it. Notice of course that you must be entered as a master user to change these settings. Entering a 1 disables, and a 0 enables.

Special codes:

Resetting the entire unit:

Reset the display only:

*0000

Clear all:

*0CAL or *0252
