XS Systems (red boxes)- The most common problems are in the Timer power and mode settings. Others can be fixed by simply replacing the batteries or resetting the unit. Try to isolate the problem by setting up the units one at a time in a controlled environment. Start with all of the components powered off then power on the Timer. Slowly go through each of the options (refer to instructions), then sync other components one at a time until the system setup is complete and working, or the problem has been reproduced. Once the problem has been isolated, refer to the trouble shooting guide for instructions on fixing the problem.
