I have a Heidolph Unimax shaker platform with a Incubator 1000 heated air circulator for temperature control. I would like to be able to cycle the heating on and off with the Incubator 1000 but keep the fan running while not heating. I realize that this would require some surgery to the hardware.
Has anyone done this sort of stuff before?
I'd find the wires to the heating element, put a SSR in the way (Crydom, by preference: after deducing if it's AC or DC powered) and then have a standalone thermal controller (30 USD from Aliexpress, more for 'cough' proper devices like a CAL9000).
Done.
Oh, and feed the controller with a thermocouple appropriate to the temperature, or a Pt 1000 or 100 thermistor.
All fairly straightforward, might just be fiddly depending on how accessible the heater wires are.
