Actually I have two questions but will post the other separately. I do a huge amount of repair and maintenance work. Every time I get involved in HVAC sytems and have to wire up a thermostat I get lost. The system I"m currently working on is a new Rheem heat pump. Wires coming from the package unit are pretty standard... red, yellow, green, blue, brown, white(with black stripe). There are 8 terminals in the thermostat (White-Rogers 1F89-211). In general I'm following color codes but am confused as to where the blue and brown wires go although I know the brown is the common for the transformer. The terminals in the thermostat are marked O/B Y G W2 E C L R ... so... which wire goes where????
