Chapter 8: Timers Menu
The ReefKeeper Lite has 16 timers that can be used. Timers have a number of settings that allow
them to be used in powerful ways. Timers are used to run on/off cycles that can be linked to a
variety of functions. They can be set to turn on for specifi c days of the week, have their durations
be set to random and have added repeat cycles.
