How do you want to control when the heater turns on? Is it the same time everyday? Just weekdays? Should it turn itself off after x-amount of time? Do you need a user interface (lcd+buttons) to set the time? Do you want to schedule the next on-time and duration? Is it scheduled based on a realtime clock or some # of hours in the future? or be able to cancel the next warmup? how may button clicks can you tolerate?
