I am replacing a Seco TA2000 thermostat with a Hunter 44155C thermostat and need to know how the wires are to be connected. Current connections are (2)White, (O)Orange, (X)Green, (R)Black, (Y)Brown and (G)Blue currently connected. Red and Yellow are present but not connected.

The colors used aren't a standard configuration. Check the thermostat wire connections at indoor unit, noting which colors are connected to which terminals. Post results.

The connections are as stated above - Current connections are (2)White, (O)Orange, (X)Green, (R)Black, (Y)Brown and (G)Blue currently connected. Red and Yellow are present but not connected. I need to know which wires go into G, RC, RH, Y/O, W/B and Y1 on the Hunter unit.
