1 GENERAL INFORMATION

1.1 USES

The NMT (new motor technology) circulating pumps are used for the transfer of liquid medium within systems for

hot‐water heating, air‐conditioning and ventilation. They are designed as single or twin variable‐speed pumping

aggregates where the speed is regulated by electronic device. The pump constantly measures pressure and flow

and adjusts the speed according to the set pump mode. The main purpose of the twin pump is uninterrupted

operation if one of the pumps fails. Common hydraulic housing is equipped with a change‐over flap and two pump

heads, separately connected to the electrical grid.

1.3 PUMP MAINTENANCE, SPARE PARTS AND DECOMMISSIONING

Pumps are designed to operate without maintenance for several years. Spare parts will be available for at least 7

years from the warranty period expiration.

This product and its components must be disposed of in an environmentally friendly manner. Use waste collection

services, if this is not possible, contact the nearest IMP Pumps Service or authorized repairers.

2 SAFETY

These instructions should be studied carefully before installing or operating the pump. They are meant to help you

with installation, use and maintenance and to increase your safety. Installation should only be performed with

regards to local standards and directives. Only qualified personnel should maintain and service these products.

Long press:

5 seconds together with and keys to restore pump to factory settings.

5.1.1.2 TURNING ON AND OFF

On first start up the pump will operate with factory settings in automatic mode.

With subsequent start‐ups, the pump will operate with the last settings that were set prior to its shut‐down.

To switch the pump off, press and hold the key for 5 seconds, until OFF is shown on the display. When the pump

is switched off, the numerical display shows OFF.

To turn the pump on, press the key briefly.

5.1.1.3 PUMP MODES AND PARAMETERS

For transition between modes, we hold the key for 3 seconds and then select the mode in which we wish the

pump to operate with or keys. We confirm the selection with the key.

After confirming the mode, the parameter, which can be set, will automatically be displayed and blink (except for

auto mode). If necessary, we set the parameter value with and keys, and then confirm the setting with the

key or just press the key to accept the given parameter.

We can scroll through the parameters within a mode with and keys. We select the parameter that can be

adjusted (see individual mode) in the mode with the key and set the desired value with and keys. We

confirm the selected value with the key.

5.1.1.4 SETTING THE PUMP TO THE FACTORY SETTINGS

To restore factory settings to the pump, it is necessary to press and hold all three keys for 5 seconds. The pump is

set to the automatic mode of operation. The previously set values for pressure and speed will be deleted.

5.1.2 DIGITAL INPUTS

There are two digital inputs available on the pump, that have different functionality. Inputs can be set by Ethernet

connection on the settings page and overviewed on the overview page.

13

To operate IO2, pumps 24V power supply can be used.

5.1.3 RELAY OUTPUT

The relay output can be set by Ethernet connection on the settings page and overviewed on the overview page.

The relay output can be configured to:

Configuration Description

Run[Default] Shows when pump is running

Operate Shows when pump is standby

Error Shows when pump has an error

No function Relay output doesn’t show anything

5.1.4 ETHERNET

The pump has a built in web server which allows you to access your pump directly via an existing Ethernet

connection.

The web server uses HTML pages to set/view:

Regulation mode settings

Regulation parameters (power, RPM, head, flow)

Relay settings

External control inputs settings

Current and previews error

Pump statistics (power consumption, run time and other).

5.1.4.1 HTML PAGES

There are five available HTML pages that offer different options.

1. Overview (default page when you connect to the pump, web page OVERVIEW) displays pump operation

summary like:

Power consumption,

Grid current,

RPM,

Estimated head,

Input Function Function description

IO1

Run[Default] Start/stop pump

Max Sets pump to operate with maximum power

No function No function

IO2

Run Start/stop pump

Max[Default] Sets pump to operate with maximum power

Pressure switch Decreases RPM when active

No function No function

14

Estimated flow,

Estimated efficiency,

Motor status,

Heatsink temperature,

Operating hours,

Number of restarts,

Energy consumed,

Remote control.

2. Pump settings (web page PUMP) is meant to provide regulation and control (input and output) settings. It has

control over:

Pump head(Limit head setting),

Ratio between head and flow HQ% (Hmax proportional to Q setting),

RPM limit (Limit rpm to setting),

Power limit (Limit power to setting),

Grid current limit (Limit grid current to setting),

Heatsink limit (Limit heatsink temperature to setting),

Relay control(Switch relay control when setting),

Input control (Input I1 and I2 setting),

Setting can be saved to permanent memory by pressing the SAVE button. Pressing TEST you will set the setting, but

will not save them, previous setting can be restored by pressing RESTORE button.

3. Network settings (web page NETWORK) provide a way to change network configuration:

Pump IP address ‐ is a pump network address. The pump is seen as http server on this address, default:

192.168.0.245 (Pump IP address setting)

Subnet mask ‐ sets subnet address range that is on the same subnet and can be reached directly. The rest

of communication goes over the gateway, default: 255.255.255.0 (Subnet mask setting),

Default gateway – provides connection route to larger networks. This is usually a router address, default:

192.168.0.1 (Default gateway setting),

NetBIOS name ‐ is a local network name service. Instead of ‘192.168.0.245’ you can for example use

'http://nmtpump'. Default: nmtpump (NetBIOS name setting),

Twin mode with IP ‐ will connect two pumps for alternating operation. When two pumps are configured

for twin mode, they will switch about once per day. Setting this field to inexistent IP will disable this

option! Set it so the first pump references the second and vice versa. Default: 0.0.0.1 (Twin mode with IP

setting).

Setting can be saved to permanent memory by pressing the SAVE button.

5.2.1 TWIN PUMP OPERATION

During normal operation, only one pump is active, while the other is in standby. Pumps change duty once per day.

Every pump operates according to its own settings, so parameter changes should be made on both pumps. If any

pump detects an error or loss of communication, the standby pump will start in less than 15 seconds.

6 ERROR AND TROUBLESHOOTING

If pump failure occurs, the error causing the failure will appear in the display screen.

Errors on the screen are identified as:

E X Y

E Error marking

X Error group

Y Service code

Error group (X)

Error description Possible cause and solution

1 Low load detected There is no medium in the pump. Check if there is medium in the system.

2 Motor overload Excessive current load or blocked rotor. If the issue persists, check if the rotor is spinning freely.

3 Motor too hot Motor has exceeded allowed temperature and is now stopped to cool down. Once cooled, it will automatically restart.

4 Electronics error An electronics error was detected. The pump can still operate, but needs servicing.

5 Motor/stator failure There could be an interruption in the motor winding. Pump needs servicing.

The service code (Y) is intended for service personal.

If the pump is unresponsive, disconnect and connect it back to the electrical grid.
