R & C from the Sage should be 24V, do you have a meter, you can confirm that. So those two go to the two right hand connections on the TPI, that powers it up. No ground, just use the two terminals provided.
What isn't clear is the two left connections on the TPI, I think they are dry contacts, a meter would confirm that since the wiring diagram is not real clear.
If so jumper from Red on the right terminals to either left terminal, that puts you hot leg on the switch, the other left terminal gets white wire back to W on the Sage. That will send the signal back to the Sage, which in turn opens the Z-one.
The Z-one end switch after 15 seconds turns on the call to the boiler, indicator lights on the Sage confirm the Z-one has made it's end switch.
Maybe someone else here knows the TPI and IF the left two connections are a dry contact.
The fact that the wiring schematic shows either 120V or 24V on those connections makes me think it is just dry contacts that you apply power to?
