How to configure pgpool2 to only balance requests?

Question

PostgreSQL

Good afternoon!
The task is to organize a cluster with the following scheme:
5 x postgres + repmgr (WAL repl) => pgpool (select load balance) => pgboucer (pool connection)
I could not accumulate comprehensive information on the pgpool configuration in such a way that it:
1. balances select requests between all nodes;
2. monitored the primary-server and sent requests for changing/introducing data to it;
3. did not try to act as a failover manager, because repmgr does this.
I honestly tried to read the documentation, smoke instances, but did not find an unambiguous solution.
