Load Pump Min Speed:
This is the lowest % of PWM signal
the pump will run, regardless of Delta T setting.

•
Load Pump Max Speed:
This is the highest % of PWM signal
the pump will run, regardless of Delta T setting.
•
Delta Temp Cool Setpoint:
This is the pump speed that will
maintain the Delta T (temperature difference) between
entering and leaving fluid 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
attempt to deliver 45 deg. F leaving fluid temperature to the
system.
•
Delta Temp Heat Setpoint:
This is the pump speed that
will maintain the Delta T (temperature difference) between
entering and leaving fluid 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 RPM to
attempt to deliver 98 deg. F leaving fluid temperature to the
system.
Alarms
The system contains an advanced network of sensors for system
monitoring of optimal running conditions. If a problem should
occur, these sensors will quickly identify the issue. In such a
situation, the HMI displays a red LED, and flashing “ALARM” text
on the screen. Additional details about an alarm can be viewed
in “Alarm Info” under the menu.

system.
⚠
NOTICE
⚠
THE SYSTEM WILL ADJUST PUMP SPEED TO MAINTAIN AT
LEAST 4 GPM REGARDLESS OF DELTA T OR MIN. % SETTING.
