hi everyone, I just purchased an ecobee 3 and pulled in a new 7 conductor thermostat cable. once I had everything all wired up, it turned on the A/C, and furnace blower fan even though I had the stat set up for heat mode only. I disconnected the yellow and green wire at the furnace terminal board to check voltage(just to make sure the furnace was not back feeding 24 volts up to the thermostat), and I have 24 volts on both wires, has anyone else run into this problem?
