Description
The Taco Post Purge Plug-In Card is a solid state control. Once the priority zone is satisfied, it maintains power to the circulator and/or the zone valve attached to the priority zone - but doesn't fire the boiler. The circulator purges excess heat into the priority zone, minimizing stand-by loss during warm weather months and optimizing boiler operation when used with a boiler reset control. Power can be maintained to the priority zone from twenty seconds to seven minutes by means of an adjustable potentiometer. An extra set of dry contacts is provided on the card to emulate the aquastat closure. This allows use of the Taco PC600 with boilers that have an integrated reset control.
