I'm looking at building a glycol setup, and I keep seeing aquarium chillers on Ebay that have what look like modified STC-1000 controllers, but the temperature range is limited to 10°-50°C (50°-122°F). Has anyone had luck swapping out the stock controller with an STC-1000 or ITC-1000 for lower temps?
