Review on Honeywell TR75VA001 Circuit Breaker Transformer by Bobby Martinez

This transformer works great for the zone valves on my boiler. The device is designed to operate with approximately 6 zones (at least with Taco Zone valves). The breaker is a bonus in case you get confused or the valve fails. It's bulky but surprisingly strong when mounted on a 4-inch electric plate held in place by just a breakaway nut.
