Thermostat Wiring Help
Here's my issue: I have a little tiny greenhouse (more of a box than a house) that I am raising vegetable seedlings in until the night temps are warm enough to transplant into the garden. During the day the temps are starting to get hot to the point that I need to install an exhaust fan.
I have an old 12V PC fan and a 12V wall adapter power supply that I'd like to connect together with a thermostat. I have an old Honeywell manual dial thermostat that should work, but I need some wiring help. The thermostat has the following wiring connections: G, RC, RH, Y, A, O, W, and B. I only have two wires coming from the power adapter (hot and return), so where do I hook them to on the 'stat to make the fan work? Remember that the honeywell is not digital, and should work with this application.
