Bosch Greenstar ZWB-35 - External Pump

Installing the combi boiler in a 2-zone setup with one external circulator pump on the supply side. I see that I can hook the zone wires to the Bosch directly to send the call for heat.

I don't see anything in the documentation on how to power the pump. Do I need to add a zone control panel to the setup or is there a way to do it directly from the boiler?
