After thirteen years, you have gotten your money's worth out of that one.
I don't really understand 'options'. Replacement is replacement. If you are looking for what to replace it with, I like the Nelson/Signature controllers. They are AFAIC the easiest and simpelest controller for the consumer to operate.
How many zones do you have? Is your conroller indoor or outdoor mounted? You have two schedules, Nelson/Signature have two for the indoor 4 & 6 zone controllers, and three schedules (a,b, & c) for the indoor/outdoor controller
Are you knowlegeable/skillfull enough to install and program the new controller yourself?
