Setting up a Taco Post Purge Timer
Would like to install a Taco PC-600 post purge timer into a Taco SR504EXP zone control box with the intent on allowing the circulators to run for a set time after the call for heat shuts the system down. The post purge feature is built into the Burnham ESC boiler being used, but was disabled by design when the zone control box was utilized.
I see in the instructions the card apparently only controls the priority zone.

Even though it's a four zone control, the system is set up with two zones and since there is no indirect hot water (domestic hot water is still from an old tank) the priority zone is not active.
Will this card post purge any of the heating circulating pumps, and if so how should it be set up?
