Hi,

The flow switch signal is connected to Digital Input CH15b. To bridge it out connect a plain wire jumper between +C to*CH15b. The 24VAC connections on 11 & 12 will no longer be required.

It's a different chiller but the link below shows a similar flow switch with contacts between the terminals as listed.*

Provided this works, a traditional paddle style or differential pressure type of switch with voltage free contacts fitted between +C & CH15b should work fine.
