What the difference between the 548 and 549?
549 has a solar panel to recharge your AA rechargeable batteries
549 Has a rain sensor (In wet areas, simply put a dab of silicone over the 2 contacts if you do not wish to have the sensor work)
549 Is programmable (similar to our 544) but is much easier to program
Ok you guys, some of you aren't reading the instructions: MAKE SURE WHEN SETTING A TIME TO COME ON THAT'S EARLIER THAN THE EXISITING TIME, THE TIMER WILL COME ON YOUR SET TIME ON THE NEXT SCHEDULED DAY.
For instance, if you are setting the clock and it's 11:00 am, and you set the timer to come on at 7 am, it's not going to come on until the next scheduled day, as it is already past 7 am when you are setting the timer.
