Durable Construction: Engineered to withstand the thermal stress of frequent cycling in demanding HVAC environments

you must use the ZDB-AF or corresponding series-specific rotation limiters to ensure proper fitment and mechanical strength

It is engineered with accurate 1

Current-Limiting Performance: Restricts the total energy flow during a fault to protect sensitive downstream components

The Copeland Comfort Control (White Rodgers) 90-341 Relay is a heavy-duty

Utica-Dunkirk 14660001 Spill Switch Durable Construction: Engineered to withstandThe Utica Dunkirk 14660001 Spill Switch is a critical vent safety switch engineered specifically for Dunkirk PWXL boilers and compatible Utica gas fired steam boilers. As a primary safety control, this thermal sensing component monitors the draft hood for abnormal flue gas spillage resulting from chimney obstructions or downdrafts. Calibrated to a 340F activation temperature, the switch breaks the electrical circuit to the gas valve when excessive
