This past weekend I purchased one of those new Wifi thermostats from Home Depot. I have the extra thermostat wire at the thermostat and at the furnace but cannot figure out where to tie it down in the furnace. I have an all electric furnace model ARUF024-00jA-1. There is no spot on the circuit board for the
"C" wire. My thermostat wires are connected to other wires with wire nuts. Is there one particular wire in there that is 24volts AC? There is a terminal that has COM next to it but it has a purple wire that runs to the blower motor connected to it. Anyone help finding a 24 volt ac wire would be greatly appreciated. Thanks.
