Email just told me that my STS-1000+ has arrived in the mail, going to go home and swap it for the existing STS-1000 control box so I can start playing with ramping ferm temperatures (and stop googling F to C conversions).

Eventually the 1000 will control the keezer and the 1000+ will control the ferment chamber I am building directly on top of the keezer (with fans blowing cold air up from the keezer, a la something like this but less nice looking:
