Level
VSD full speed level This is the analog level at which all the pumps will be running at full speed. Ensure that it is set lower than
the setpoint if the control direction = ‘Fill’ and higher than the setpoint if the control direction = ‘Empty’.
VSD speed at stop
level
This is the speed the pumps will be running at when at the setpoint stop level.
Manual speed This is the speed a VSD controlled pump will run in manual. If the system is in auto and a duty or standby
pump is running then the auto speed will override the manual speed.
Pressure
PID Proportional Proportional is the controlled speed response based on the analog feedback distance from setpoint
when configured for pressure VSD. ‘Increase’ = More responsive, ‘Decrease’ = Less responsive. See Step
5.11 on the next page for more information on setting the PID.
PID Integral Integral is the controlled speed response based on the analog feedback time from setpoint when
configured for pressure VSD. ‘Increase’ = Slower response, ‘Decrease’ = Faster response. See Step 5.11 on
the next page for more information on setting the PID.
VSD No demand
speed
Once the pump speed has dropped below the No demand speed for the Sleep delay the system will go
to sleep. See Step 5.12 on the next page for more information on setting the No demand speed.
Manual speed This is the speed a VSD controlled pump will run in manual. If the system is in auto and a duty or standby
pump is running then the auto speed will override the manual speed.
Pipe fill If enabled, when the system wakes up from sleep and the analog pressure is more than 20% of the
transducer range below setpoint the system will run a single duty pump at 45Hz to increase the pressure
slowly. If the pump fails to increase pressure to less than 20% of the transducer range from setpoint in 10
minutes a pipe fill fault will lockout the pumps.
Sleep assist When the pump speed is not varying more than 0.1Hz for 20 seconds the system will initiate one of the
following sleep assist modes if selected. ‘Speed minimise’ will slowly drop the pump speed to try and
reach the No demand speed. If the pressure drops from setpoint the system will resume normal running.
‘Boost’ will temporarily adjust the setpoint to setpoint + sleep boost pressure increase to increase the
system pressure, before returning to the normal running and setpoint. This should slow the pump speed to
below the No demand speed if there is no system demand.
Sleep boost pressure
increase
This is the target pressure above the setpoint which the sleep boost will try and reach before returning to
normal operation.
Temperature
VSD full speed
temperature
This is the analog temperature at which all the pumps will be running at full speed. Ensure that it is set
lower than the setpoint if the control direction = ‘Heat’ and higher than the setpoint if the control direction
= ‘Cool’.
VSD speed at setpoint This is the speed the pumps will be running at when at the setpoint.
Manual speed This is the speed a VSD controlled pump will run in manual. If the system is in auto and a duty or standby
pump is running then the auto speed will override the manual speed.
