The 7.5 won't be an issue, as it was just used by the thermostat itself, and was usually 12 anyway. The control signals back to the main board are all grounds with that setup. Most electronic thermostats are battery powered, so supply voltage is irrelevant, but I have no knowledge of the EccoBee
On edit, I looked at the EcoBee, and it's hard to say if it would work on 12 volt power. Worst case, wire in the pek kit.
