Description
The Xylem-McDonnell & Miller 7B1R Resistor is used with 7B switch assemblies to provide resistance input for level control adjustment, supporting accurate operation in HVAC systems. It now includes the SA7-3 slide wire kit for calibrated setting of control response. It operates by varying electrical resistance to reflect level changes, enabling the switch to respond according to set points. Connected within control circuits of level monitoring assemblies, it interfaces with switches and related components to maintain proper system response and operational control.
