System Start Up Procedure
Adjusting Sleep Function –
Parameter B5-15 in Set Up Menu “STUP”
Perform system static pressure test:
 With pump running, allow all the control
valves to close.
 Make note of the pressure on the liquid filled
gauge assembly.
 Press the “STOP” button on the drive. Wait
between one and five minutes to see if the
system is able to hold the static pressure
between the check valve before the pump
and the control valves. If the system is not
able to hold the pressure maintained on the
drive, please refer to the troubleshooting
section of this manual (page 17).
NOTE: Use good quality 2-way control
valves that will provide a 100% closed
seal with no leakage.
 If the system is able to maintain pressure,
then allow flow to the smallest capacity
(GPM) heat pump.
 Press the “RUN” button on the drive to allow
flow to the smallest unit. Make not of the
frequency (Hz) on the home screen of the
drive during this operation.
 To enable the stop function, you must
change parameter B5-15 to 1-3 Hz below
the operating frequency on the smallest unit.
NOTE: The drive must be in the stop
position to make this change.
 After this has been set, go back to the home
screen by pressing “ESC” key three times.
 Press the “RUN” button At this point the stop
function has been set. You can cycle through
all the individual heat pumps to ensure that
the stop function is working properly. If the
motor is not stopping or cycling, please refer
to page 17 to troubleshoot the stop function.
NOTE: If you have any questions, please
contract your distributor.
Setting the Dry Run Protection –
Parameter B5-12
 By default the drive setting for Parameter
B5-12 = 0 (disabled).
 Go to the Set Up Menu “STUP” and change
B5-12 = 2 (Dry Run Enabled) Refer to page
10 to navigate the drive menu. This setting
ensures that there is the proper amount of
water in the canister.
NOTE: The Dry Run Protection (B5-12 =
2) must be enabled to prevent damage
to the pump, motor and piping. This
setting will shut down the pump if the
canister were to run dry due to a leak.
