Don't know anything about this pedal, and their Web Site has no information either.

But, assuming it is just a momentary switch, you have two choices. One of them is to connect it to both pedals with a Y-lead. The other is to pick one pedal as the tempo master, and have it control the other via MIDIclock (you will need to enable MIDIclock out on the master, and MIDIclock in on the other – see UM for info).
