• Load Pump Max Speed: This is the highest % of PWM
signal the pump will run, regardless of Delta T seng.
• Delta Temp Cool Setpoint: This is the pump speed
that will maintain the Delta T (temperature dierence)
between entering and leaving uid temperatures. For
example, if the Delta Temp is set at 5 deg. F and the
entering temperature is 50 deg. F, the pump speed will
increase/decrease RPM to aempt to deliver 45 deg. F
leaving uid temperature to the system.
• Delta Temp Heat Setpoint: This is the pump speed
that will maintain the Delta T (temperature dierence)
between entering and leaving uid temperatures. For
example, if the Delta Temp is set at 8 deg. F and the
entering temperature is 90 deg. F, the pump speed will
increase/decrease spped to aempt to deliver 98 deg. F
leaving uid temperature to the system.
⚠ NOTICE ⚠
THE SYSTEM WILL ADJUST PUMP SPEED TO MAINTAIN
AT LEAST 4 GPM REGARDLESS OF DELTA T OR MIN. %
SETTING.
