IntermaticPb913n66 W/override F/rc2343pt New

Is this a replacement for pb912m10 motor 125v 60 hz?

What are the dimensions of this unit? I'm building my own ozone purifier for my hot tub, and need to fit this into the weatherproof box.

Does this timer have a low temperature override, to turn the heater / pump on before it freezes?

Does this timer come with yellow and black connector wires?
