Hopefully somebody can help. A/c’s run fine , change to heat on incommand and no furnace operation. Few calls to in command they say gate way bad….replace gateway same problem. I jumped the blue thermostat wires at the furnace and furnace wires up and works fine. I’m about to buy a manual thermostat and run my furnace from there instead of through incommand system. Any thoughts? When I switch from a/c to heat I hear a relay click in rear a/c unit which is normal but the a/ c is not telling the furnace to turn on. Any help would be appreciated.
Thank you
