4. Select one of the four below parameters using the settings button
(5).
– BAUD = baud rate setup (available values 4.8 - 9.6 - 14.4 - 19.2 -
38.4 - 56.0 - 57.6 kbps)
– PROT = communication protocol (available protocols “mod” =
Modbus; “bac” = BACnet
– ADDR = address setup (available address 1-247 for Modbus 0–
127 for BACnet)
– MODU = optional module setup (“none” = no module; “wifi” =
Wireless module; “485” = RS-485 module)
5. Press the parameter button to enter the submenu
6. Edit the values using setting buttons.
7. Press the parameter button to confirm and store the new values.
8. Press mode button to exit the submenu.
9. Repeat above procedure for each of the three parameters.
If no buttons are pressed for 10 seconds, then the pump exits the cur-
rent menu and continues start-up procedure. All the parameters that
are changed but not confirmed restore back to previous state.
NOTE: The communication setup menu is available only on display and
not through communication bus.
6.1.2 Change the control mode
The pump can be controlled by a BMS (Building management system)
or other devices through the RS-485 communication port via Modbus
or BACnet protocol.
The following instructions are used when making the change on the
user interface. See
on page 9.
• Press the operating mode button (1).
• The operating modes are cyclically changed by the pressed button.

6.1.3 Change the set point
1. Press one of the arrow setting buttons (5).
The display starts to blink.
2. Change the value using the buttons (5).
3. Wait 3 seconds to store and activate the new set point.
The display will stop blinking to confirm the change.
NOTICE:
If a check valve is installed in the system, ensure that the pump head is
sufficient to allow flow through the system
6.1.4 Change the displayed unit of measurement
Power, Flow, Head and Speed parameters cyclically change by press-
ing the parameter button (3). In order to change the unit of measure-
ment, follow these steps:
1. Press the button (3) to change the unit of measurement. See
on page 9.

2. When flow and head are displayed, by pressing the button (3) for
more than one second at each of these parameters, the unit of
measurement automatically changes as below:
– Flow: m3/h
↔

– Head: m
↔

6.2 Start or stop the pump
CAUTION:
• The pump must not run dry as this can result in premature
failure of the bearings in a very short time. Fill and vent
the system correctly before first start-up. The pump rotor
chamber will be vented after the pump is powered on
with an automatic air venting procedure. "deg" will be dis-
played indicating degassing process.
NOTICE:
The system cannot be vented through the pump.
• Start the pump in one of the following ways:
– Switch on power to supply the pump.
– Close the start/stop contact by jumpering terminals 11 and 12
on single phase pumps and terminals 13 and 14 for three phase
pumps, or through a remote dry contact..
– Send start command through the communication bus.
The pump starts pumping in constant pressure mode with the fol-
lowing default set points:

52.5 ft
105–XX (Max head 105 ft)
For more information about how to change setting, see
on page 11.
• Stop the pump in one of the following ways:
– Switch off power supply to the pump.
– Open the start/stop contact.
– Send stop command through the communication bus.
6.2.1 Automatic air venting procedure
At each power-on of the pump unit, an automatic air venting proce-
dure is executed. During this phase, the user interface displays "deg"
(degassing) and a count-down begins until the completion of the pro-
cedure.
The air venting procedure can be recalled or skipped:
• Manually by pressing simultaneously the two buttons (5). See
on page 9. The feature will remain disabled until power to
pump is disconnected.
