HOFFMAN SERIES 21H - TEMPERING VALVE Excess Pressure Pump Model 21LT 100–140°F (38–60°C)

Model 21LT 100–140°F (38–60°C)

the control will turn off the boiler if it recognizes an out-of-water condition when the sensivity threshold is exceeded

Model 21LT provides the greatest accuracy of temperature control

so to change the rotation on the pumps simply loosen the bolt that holds the pump-end to the motor

All programmable parameters are stored in non-volatile memory
