hello the group: I've just installed a new "mercury-free" thermostat in my shop. I looked the thing over and realized it has everything needed to control a "constant temperature" enclosure. There's a diode used as temp sensor,easy to remote with two wires, a place to put two AA batteries, a pot to adjust the set temperature, all needed circuitry for a bang-bang controller with 1deg F hysteresis, uses a latching relay so the batteries last a long time, a low battery indicator, and an easily backengineered circuit board, and a low price. There is provision for external power as well. The one I bought is a rite-temp model 6005; distributed by home despot. And it's relatively cheap, about 20 devalued rasbuckniks. All that's required is whatever needed for a heater and its power supply. Unfortunately, not for 110 volts but I didn't look at the relay to get the capability; that may be a lawyer problem rather than a capacity problem. Don
