I have a Robertshaw 300-226 hp stat. it has w y r c g b & o connections. y turns on the compressor & w turns on auxiliary heat. b & o select heating or cooling respectively.
I have a 2 stage furnace & wish to know whether this stat wil work with it.
If I connect b(stat) to w1 (furnace) & w(stat) to w2 (furnace) would this work to control 2 stage heating on the furnace?
Is b(stat) at 24 volts like w1, w2 normally are ?
b is powered anytime the heat cool selector switch is in heat mode so no, your connections will not only not work but will kill your HP. Without directly telling you how, yes that stat will work.
