Installing Honeywell RTH230B, what to do with blue (B) Wire
I am trying to install of Honeywell RTH230B thermostat. I removed the old Lux mercury thermostat and their were five wires Rh, W, Y, G, and B (blue).
The thermostat has place for all of the wires except the B(blue) wire. Do I need a different thermostat or can the B wire be put in the Rc space or not used at all? |
