Application
The 193-7BM is designed for use on steam boilers where both low water protection and pump control are required. The manual reset feature ensures that operators must physically acknowledge and reset the control after a low water event, preventing automatic restart until the condition has been investigated and resolved — a critical safety protocol in steam boiler operation.
