DCW_CONDENSATE_RECOVERY
Condensate / reclaim sump transfer with quality-gated divert, stagnation refresh and recovery totalising.
When to use it
Use DCW_CONDENSATE_RECOVERY when air-handler condensate, blowdown reclaim or harvested rainwater is collected in a sump and transferred to a makeup or break tank, and off-spec water must be diverted to drain rather than admitted to the treated inventory.

Supervised control write
DCW_CONDENSATE_RECOVERY commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
