The Ranco ETC-211000 is identical to the Ranco ETC-111000 except that this unit is 2 stage, and has 2 relays to control both heating and cooling at the same time or two heating or cooling stages. (The output relay NC and NO ratings are also different than the single stage control).

This is what I am looking for or some thing similar.

Whatever you do, do not get an Aquamedic Biotherm Controller. I dont think they make them anymore but there are probably some used ones kicking around. I bought several a few years ago and they have all caused me problems. Garbage.
