Looking for wiring help to give my Ecobee3 control over my older vanEE constructo 1.0 air exchanger. I have a 20 min lighted push button aux control on the upstairs wall directly below my Ecobee3 thermostat & I'm hoping I can just run a jumper wire from that switch into the acc ports of my Ecobee3. I've attached a photo of the back of my aux control switch. Can anyone help provide guidance on how to do this?
