The next generation of Bell & Gossett ZoneTrol™ II zone pump controllers with optional outdoor reset control makes them ideal for green building applications, says the company. The new pump controllers are ready-to-install zone controllers for hydronic circulators in residential and light commercial applications. Standard features include domestic hot water priority timer, post-purge function, and pump exercise. All ZoneTrol II controllers are UL and cUL listed and feature multifunction LEDs that are visible without removing the cover for simplified startup and troubleshooting. All 10 models are compatible with analog and digital 24-vac thermostats, including “power stealing” designs. Four- and six-zone controllers are field-expandable for up to 18 pumps and are available with integrated, pre-wired boiler reset or mix reset controllers. Units with reset controllers also include all of the necessary sensors. All the controllers come with a standard five-year warranty.
