Do the instructions say you can use this thermostat on a 12 volt DC system? Your house is 24 volt AC power.
The industry standard on the new thermostat terminals is:
Red = power in
White = heat
Yellow = air conditioner
Green = fan
On the old thermostat the blue wire is "ground" providing power for the thermostat between it and the red wire. Cap off the BLUE WIRE before you short out the new thermostat!!!!!!
If this was your house:
Connecting the Red wire to Yellow would start the air conditioning compressor.
Connecting the Red wire to Green would start the fan
Connecting the Red wire to White would start the furnace.
This thermostat is not designed to support a two speed fan. Cap the grey wire.
I don't believe you can get by with tying the high and low speed fan wires together with burning something up. Were did you find the information saying this thermostat is correct for your application?
The "B" and "O" terminals are only used on heat pump applications.
