Can I use ACC+ and ACC- on my Ecobee 3 to power a relay?

I'm wanting to install a motorized damper and my ERV to the Ecobee 3. If the ACC+/- terminals will power a relay, I can get a DPDT relay to power the damper and ERV to both turn on at the same time when it sees a signal from the Ecobee, Does anyone know the output signal from these contacts?
