How to connect a Saswell scu209led-tm1 output to a Grant Vortex boiler

[satro1]

Hi Installed UFH Manifold, pump, Valve etc, connected to a Saswell scu209led-tm1 Connection Box. On the terminals marked "com" and "no" going to the Boiler. Which terminals on a Grant Vortex Boiler do these 2 connectors go too?
Thanks in advance

Wheres the two port valve wired into?

Wants wiring as an S plan. Is it a heat only/system boiler?
