I've happened upon a True GDM-26 for use as my fermentation chamber. I've seen references to using an STC-1000/Love/Ranco with these units. What is the recommended approach in wiring these? Bypass the internal thermostat, or can it be plugged in to a Ranco without short cycle issues?
My goal is simplicity (Ranco), but if the best approach is the more complex (Love) one that's fine. I have so much invested in this new system the extra time/cost is irrelevant at this point.
If you have that much invested, it might be prudent to go with the Love controller, as the Ranco doesn't have an anti-short-cycle function. The wiring complexity for any of the three makes you mentioned is essentially identical...
I installed my STC-1000 in the bottom louvers on my TRUE GDM-10 Fermentation Chamber. The existing thermostat is bypassed. Existing wires were used between the lower and upper enclosures. I ran the probe wire through the existing wiring hole in the floor of the unit. The Heat 1/2 duplex receptacle (and an always Hot other 1/2, not on schematic) were installed in the original thermostat cut-out, in case I needed to control a smaller heater or use some other AC device inside the chamber.
IMO, bypassing the thermostat is a better option in that it allows the evaporator fan to run constantly, which promotes defrosting and air circulation.
The heat strip turned out to be oversized and I haven't actually needed to use it all winter.
