3.1 Location

The pump is designed for indoor installation. Always install the pump in an dry environment where it will not be

exposed to drops or splashes, for example water, from surrounding equipment or structures.

As the pump contains stainless-steel parts, it is important that it is not installed directly in environments, such as:

• Indoor swimming pools where the pump would be exposed to the ambient environment of the pool.

• Locations with direct and continuous exposure to a marine atmosphere.

• In rooms where hydrochloric acid (HCl) can form acidic aerosols escaping from, for example, open tanks or frequently opened or vented containers.

The above applications do not disqualify for installation of MAGNA3. However, it is important that the pump is not installed directly in these environments.

Stainless steel variants of MAGNA3 can be used to pump pool water. See section 6.2 Pumped liquids.

To ensure sufficient cooling of motor and electronics, observe the following requirements:

• Position the pump in such a way that sufficient cooling is ensured.

• The ambient temperature must not exceed 40 °C.

3.3 Mechanical installation

The pump range includes both flanged and threaded versions. These installation and operating instructions apply to both versions, but give a general description of flanged versions. If the versions differ, the threaded version will be described separately.

Install the pump so that it is not stressed by the pipes. For maximum permissible forces and moments for pipe connections acting on the pump flanges or threaded connections, see page

64.

You can suspend the pump directly in the pipes, provided that the pipes support the pump.

Twin-head pumps are prepared for installation on a mounting bracket or base plate. The pump housing has a M12 thread.

8.8.3 "Multipump setup".

6. Product introduction

Right pump head

Left pump head

MAGNA3 is a complete range of circulator pumps with integrated controller enabling adjustment of pump performance to the actual system requirements. In many systems, this reduces the power consumption considerably, reduces noise from thermostatic radiator valves and similar fittings and improves the control of the system.

You can set the desired head on the operating panel.

6.1 Applications

The pump is designed for circulating liquids in the following systems:

• heating systems

• domestic hot-water systems

• air-conditioning and cooling systems.

You can also use the pump in the following systems:

• ground-source heat-pump systems

• solar-heating systems.

6.2 Pumped liquids

The pump is suitable for thin, clean, non-aggressive and non-explosive liquids, not containing solid particles or fibres that may attack the pump mechanically or chemically.

In heating systems, the water must meet the requirements of accepted standards on water quality in heating systems, for example the German standard VDI 2035.

The pumps are also suitable for domestic hot-water systems.

Observe local legislation regarding pump housing material.

Stainless steel variants of MAGNA3 can be used to pump pool water with the one of the following properties:

• Chloride (Cl-) ≤ 150 mg/l and free chlorine ≤ 1.5 mg/l at temperatures ≤ 30 degrees Celsius

• Chloride (Cl-) ≤ 100 mg/l and free chlorine ≤ 1.5 mg/l at temperatures from 30 to 40 degrees Celsius.

We strongly recommend that you use stainless-steel pumps in domestic hot-water applications to avoid corrosion.

In domestic hot-water systems, we recommend that you use the pump only for water with a degree of hardness lower than approximately 14 °dH.

In domestic hot-water systems, we recommend that you keep the liquid temperature below 65 °C to eliminate the risk of lime precipitation.

Clean and flush the system before you add the ethylene-glycol mixture.

To prevent corrosion or lime precipitation, check and maintain the ethylene-glycol mixture regularly. If further dilution of the supplied ethylene-glycol is required, follow the glycol supplier's instructions.

Additives with a density and/or kinematic viscosity higher than those/that of water reduce the hydraulic performance

Fig. 16 Pumped liquids, threaded version

6.3 Pump heads in twin-head pumps

The twin-head pump housing has a flap valve on the outlet side. The flap valve seals off the port of the idle pump housing to prevent the pumped liquid from running back to the inlet side. See fig. 17. Due to the flap valve, there is a difference in the hydraulics between the two pump heads. See fig. 18.

Fig. 17 Twin-head pump housing with flap valve

English (GB)

TM05 8457 2313TM06 1565 2514TM06 1566 2514

Do not pump aggressive liquids.

Do not pump flammable, combustible or explosive liquids.

6.2.1 Glycol

You can use the pump for pumping water-ethylene-glycol mixtures up to 50 %.

Example of a water-ethylene-glycol mixture: Maximum viscosity: 50 cSt ~ 50 % water / 50 % ethylene-glycol

mixture at -10 °C. The pump has a power-limiting function that protects it against

overload. The pumping of water-ethylene-glycol mixtures affects the

maximum curve and reduces the performance, depending on the water-ethylene-glycol mixture and the liquid temperature.

To prevent the ethylene-glycol mixture from degrading, avoid temperatures exceeding the rated liquid temperature and minimise the operating time at high temperatures.

6.6 Radio communication

The radio part of this product is a class 1 device and can be used anywhere in the EU member states without restrictions.

Intended use

This pump incorporates a radio for remote control. The pump can communicate with Grundfos GO and with other

MAGNA3 pumps of the same type via the built-in radio.

6.7 Closed valve operation

MAGNA3 pumps can operate at any speed against a closed valve for several days without damage to the pump. However, Grundfos recommends to operate at the lowest possible speed curve to minimize energy losses. There are no minimum flow requirements.

Do not close inlet and outlet valves simultaneously, always keep one open when the pump is running.

Media- and ambient temperatures must never exceed the specified temperature range.

6.8 Insulating shells

Insulating shells are available for single-head pumps only.

Limit the heat loss from the pump housing and pipes.

Reduce the heat loss by insulating the pump housing and the pipes. See figs 22 and 10.

• Insulating shells for pumps in heating systems are supplied with the pump.

• Insulating shells for pumps in air-conditioning and cooling systems, down to -10 °C, must be ordered separately. See section 11.7 Insulating kits for air-conditioning and cooling

systems.

The fitting of insulating shells increases the pump dimensions.

English (GB)

Fig. 22 Insulating shells

Pumps for heating systems are factory-fitted with insulating shells. Remove the insulating shells before installing the pump.

6.9 Non-return valve

If a non-return valve is fitted in the pipe system, make sure that the set minimum outlet pressure of the pump is always higher than the closing pressure of the valve. See fig. 23. This is especially important in proportional-pressure control mode with reduced head at low flow.

Note: The pump cannot reduce the flow on the inlet side, but is able to control that the flow on the outlet side is at least the same as on the inlet side. This is due to the fact that the pump has no built-in valve.

Technical specifications

7.3.4 Proportional pressure

Proportional pressure is suitable in systems with relatively large pressure losses in the distribution pipes and in air-conditioning and cooling systems:

• Two-pipe heating systems with thermostatic valves and the following:

– very long distribution pipes – strongly throttled pipe balancing valves – differential-pressure regulators – large pressure losses in those parts of the system where the

total quantity of water flows (for example boiler, heat exchanger and distribution pipe up to the first branching).

• Primary circuit pumps in systems with large pressure losses in the primary circuit.

• Air-conditioning systems with the following:

– heat exchangers (fan coils) – cooling ceilings – cooling surfaces.

Characteristics and key benefits

• The head of the pump increases proportionally to the flow in the system.

• Compensates for large pressure losses in the distribution pipes.

7.3.5 Constant pressure

English (GB)

A constant pressure is advantageous in systems with relatively small pressure losses in the distribution pipes:

• Two-pipe heating systems with thermostatic valves: – dimensioned for natural circulation – small pressure losses in those parts of the system where the

total quantity of water flows (for example boiler, heat exchanger and distribution pipe up to the first branching)

– modified to a high differential temperature between flow pipe

and return pipe (for example district heating).

• Underfloor heating systems with thermostatic valves.

• One-pipe heating systems with thermostatic valves or pipe

balancing valves.

• Primary circuit pumps in systems with small pressure losses in

the primary circuit.

Characteristics and key benefits

• The pump pressure is kept constant, independent of the flow

in the system.

Technical specifications

Temperature sensor

If the pump is installed in the flow pipe, install an external temperature sensor in the return pipe of the system. See fig. 31. Install the sensor as close as possible to the consumer (radiator, heat exchanger, etc.).

TM05 2615 0312TM05 2616 0312

Fig. 31 Pump with external sensor

We recommend that you install the pump in the flow pipe. If the pump is installed in the return pipe of the system, you can

use the internal temperature sensor. In this case, install the pump as close as possible to the consumer (radiator, heat exchanger, etc.).

Select this control mode if the pump performance is to be controlled according to a differential temperature in the system where the pump is installed.

Characteristics and key benefits

• Ensures a constant differential temperature drop across

heating and cooling systems.

• Ensures a constant differential temperature between the pump

and the external sensor, see figures 33 and 34.

• Requires two temperature sensors, the internal temperature

sensor together with an external sensor.

Technical specifications

7.3.8 Constant flow Note: Available for pumps with production code from 1838.

The pump maintains a constant flow in the system independently of the head. See fig. 35.

Constant flow is suitable in applications such as air handling units, hot-water systems and ground-source heating systems.

Characteristics and key benefits

• It is not possible to use an external sensor, instead, the pump uses its internal sensor.

• In multipump systems constant flow is only available in alternating and backup operation, not cascade operation.

English (GB)

Fig. 33 Differential temperature

The differential-temperature control mode is available in model B. The model version is stated on the nameplate. See section

6.5 Model type.

Temperature sensor

To measure the temperature difference of the flow and return pipe, you must use both the internal sensor and an external sensor.

If the pump is installed in the flow pipe, the external sensor must be installed in the return pipe and vice versa. Always install the sensor as close as possible to the consumer (radiator, heat exchanger, etc.). See fig. 34.

A constant curve is suitable for systems where there is a demand for both constant flow and constant head, i.e.:

• heating surfaces

• cooling surfaces

• heating systems with 3-way valves

• air-conditioning systems with 3-way valves

• chiller pumps.

Characteristics and key benefits

• If an external controller is installed, the pump is able to change from one constant curve to another, depending on the value of the external signal.

• Depending on your preferences, the pump can be controlled according to either a maximum or minimum curve.

The pump can be set to operate according to a constant curve, like an uncontrolled pump. See fig. 36.

Depending on the pump model, you can set the desired speed in % of the maximum speed. The span of control depends on the minimum speed, power and pressure limitation of the pump.

If the pump speed is set in the range between minimum and maximum, the power and pressure are limited when the pump is running on the maximum curve. This means that the maximum performance can be achieved at a speed lower than 100 %. See fig. 37.

7.4 Additional control mode features

MAGNA3 offers additional features for the control modes to meet specific demands.

7.4.1 FLOW

The feature is an integrated part of the FLOW but can also be used in:

• You can use the minimum curve mode in periods in which a minimum flow is required. This operating mode is for instance suitable for manual night setback if automatic night setback is not desired.

You can select these two operating modes via the digital inputs. In the control mode constant curve, you can obtain constant flow

7.4.2 Automatic night setback

A night setback system is often integrated into a building management system (BMS), or as part of an equivalent electronic control system, which has a built-in timer.

The feature is not beneficial in a room that has underfloor heating because of the regulating inertia of the underfloor heating.

Characteristics and key benefits

• Automatic night setback lowers the room temperature at night, which reduces heating costs.

• The pump automatically changes between normal duty and night setback (duty at low demand) depending on the flow pipe temperature.

• Once activated, the pump runs on the minimum curve.

Technical specifications

The pump automatically changes to night setback when the built-in sensor registers a flow-pipe temperature drop of more than 10 to 15 °C within approximately two hours. The temperature drop must be at least 0.1 °C/min.

Changeover to normal duty takes place without time lag when the temperature has increased by approximately 10 °C.

7.5 Multipump modes

7.5.1 Multipump function

The multipump function enables the control of single-head pumps connected in parallel and twin-head pumps without the use of external controllers. The pump is designed for multipump connection via the wireless GENIair connection. The built-in wireless GENIair module enables communication between pumps and with Grundfos GO without the use of add-on modules. See sections 9. Servicing the product and 11.1 Grundfos GO.

Pump system:

• Twin-head pump.

TM05 2444 0312TM05 2542 0412

• Two single-head pumps connected in parallel. The pumps must be of equal size and type. Each pump requires a non-return valve in series with the pump.

A multipump system is set via a selected pump, i.e. the master pump (first selected pump). The multipump functions are described in the following sections.

Configuration of twin-head pumps is described in section

4.2 Twin-head pump.

For information about input and output communication in a multipump system, see section 7.9.1 External connections in a

multipump system.

7.5.2 Alternating operation

Only one pump is operating at a time. The change from one pump to the other depends on time or energy. If a pump fails, the other pump will take over automatically.

7.5.3 Backup operation

One pump is operating continuously. The backup pump is operating at intervals to prevent seizing up. If the duty pump stops due to a fault, the backup pump will start automatically.

7.5.4 Cascade operation

Cascade operation ensures that the pump performance is automatically adapted to the consumption by switching pumps on or off. The system thus runs as energy-efficiently as possible with a constant pressure and a limited number of pumps.

The slave pump will start when the master pump is running at maximum or has a fault, and it will stop again when the master pump is running below 50 %.

Cascade operation is available in constant speed and constant pressure. You can with advantage choose a twin-head pump, as the backup pump will start for a short period in peak-load situations.

All pumps in operation will run at equal speed. Pump changeover is automatic and depends on speed, operating hours and faults.

English (GB)

You cannot enable automatic night setback when the pump is in constant-curve mode.

7.6 Flow estimation accuracy

Max.

Min.

max

English (GB)

The internal sensor estimates the difference in pressure between the inlet and outlet port of the pump. The measurement is not a direct differential-pressure measurement, but by knowing the hydraulic design of the pump, you can estimate the differential pressure across the pump. The speed and power give a direct estimation of the actual duty point at which the pump is running.

The calculated flow rate has an accuracy specified as ± xx % of Q

. The less flow through the pump, the less accurate the

max

reading will be. The typical accuracy of the flow reading is ± 5 % of the specific pump’s maximum flow. In extreme cases, such as closed valve operation, the accuracy can be up to ± 10 % of the maximum flow.

See also section 7.9.5 Heat energy monitor. Example:

7.8 Priority of settings

The external forced-control signals influence the settings available on the pump operating panel or with Grundfos GO. However, you can always set the pump to maximum-curve duty or stop the pump on the operating panel or with Grundfos GO.

If two or more functions are enabled at the same time, the pump operates according to the setting with the highest priority.

The priority of the settings is as shown in the table below. Example: If the pump has been forced to stop via an external

signal, the operating panel or Grundfos GO can only set the pump to maximum curve.

- Separate input voltages from external equipment from live parts by reinforced insulation.

7.9.1 External connections in a multipump system

The following external connections need only to be fitted to the master pump:

• analog input

• digital input

• communication interface module, CIM If you want to monitor a slave pump, mount a communication interface module on the slave pump too.

The following external connections need to be fitted on both the master and slave pumps:

• Relays (from model B)

The following are system parameters shared between the pumps:

• Operating mode, control mode and setpoint

• Heat energy monitor: Both pumps display the heat energy for the entire system and not only for the individual pump. Please note that all calculations are made in the master pump. If the master pump loses power, the heat energy will cease to increment. See also section 7.9.5 Heat energy monitor.

For more information about input and output communication in multipump systems, see sections 7.9.2 Relay outputs,

7.9.3 Digital inputs and 7.9.4 Analog input.

7.9.2 Relay outputs

The pump has two signal relays with a potential-free changeover contact for external fault indication. See section 3.9 Wiring

diagrams.

You can set the function of the signal relay to "Alarm", "Ready" or "Operation" on the operating panel or with Grundfos GO.

The relays can be used for outputs up to 250 V and 2 A.

Warnings do not activate the alarm relay.

Use C and NC for fault signals as this enables serial connections of more relays and detection of signal cable defects.

Relay output in twin-head pumps

The relay output for both the "Alarm", "Ready" and "Operation" functions operates independently on each pump head. If, for example, a fault occurs in one of the pumps, its respective relay is triggered.

7.9.3 Digital inputs

The pump has a digital input for external control of start-stop or forced maximum or minimum curve. See section 3.9 Wiring

diagrams.

If no external on-off switch is connected, the jumper between terminals start-stop (S/S) and frame ( ) must be maintained. This connection is the factory setting.

For redundancy purposes, the digital input can be used concurrently on the slave pump head. However, as long as the master is powered up, the input on the slave will be ignored. In the event of power loss on the master, the digital input of the slave will take over. When the master pump head is back on, the master takes over and controls the system.

The pump has an analog input for the connection of an external sensor for measuring temperature or pressure. See section

3.9 Wiring diagrams.

You can use sensor types with 0-10 V or 4-20 mA signal. You can also use the analog input for an external signal for the

control from a building management system or similar control system. See fig. 51.

• When the input is used for the heat energy monitor, install a temperature sensor in the return pipe.

• If the pump is installed in the return pipe of the system, install the sensor in the flow pipe.

• If the constant-temperature control mode has been enabled and the pump is installed in the flow pipe of the system, install the sensor in the return pipe.

• If the pump is installed in the return pipe of the system, you can use the internal temperature sensor.

You can change the sensor type, 0-10 V or 4-20 mA, on the operating panel or with Grundfos GO.

The heat energy monitor calculates the heat energy consumption within the system. The built-in flow estimation needed for the calculation has a worst case accuracy of ± 10 % of the maximum flow. The actual accuracy in a duty point will be shown in the MAGNA3 display (available for pumps with production code from

1838). The temperature measurement accuracy also depends on

the sensor type. Therefore, you cannot use the heat energy value for billing purposes. However, the value is perfect for optimisation purposes in order to prevent excessive energy costs. See also section 7.6 Flow estimation accuracy.

To counterbalance any inaccuracy on either the internal and external sensor it is possible to manually enter a temperature offset. The offset is entered in integers, for example 2 degrees. The offset range is within ± 20 degrees celsius. To set the temperature offset, see section 8.7.4 "Controller settings".

Note: Temperature sensor offset is available for pumps with production code from 1838.

The flow and volume accuracy is calculated and shown in the display, see sections "Estimated flow rate, accuracy", page 39, and "Accuracy of values", page 39.

The heat energy monitor requires an additional temperature sensor installed in the flow pipe or return pipe depending on where the pump is installed.

"Linear with Min."

Here, a 0-10 V or 4-20 mA signal controls the pump speed range in a linear function. The range of control depends on the minimum speed, power and pressure limits of the pump. See figs 53 and

54.

You can measure both heating and cooling in the same system. If a system is used for both heating and cooling, two counters are automatically shown in the display. See section "Heat energy", page 39.

Monitoring heat energy in multipump systems

In a multipump system, the master pump calculates the heat energy regardless of which pump, master or slave, is running.

If the master loses power or has a fault on the external sensor, the accumulation of heat energy will not be counted until the master is powered back on or the external sensor error is remedied. If the master is replaced, the heat energy values for the system is reset.

7.9.6 External setpoint function

You can use the analog input to influence the setpoint externally. The external setpoint function can be used in two different ways:

• "Linear with Min."

• "Linear with Stop" (available for pumps with production code from 1838)

In both modes the input signal range is influenced linearly.

The external setpoint function operates differently depending on the model. For models A, B and C, the maximum speed is often obtained at voltages lower than 10 V, as the span of control is limited.

In models newer than A, B and C, the internal scaling has been optimised making the dynamic area bigger, thus giving a better control of the pump speed when using the external setpoint function.

TM05 5367 3612

The same applies if the pump is receiving a setpoint from Building Management Systems.

"Linear with Stop" Note: Available for pumps with production code from 1838.

Here, if the input signal is below 10 %, the pump changes to operating mode "Stop". If the input signal is increased above 15 %, the operating mode is changed back to "Normal".

Guidelines for setting of PI controller

For most applications, the factory setting of the controller constants, gain and integral time, ensures optimum pump operation. However, in some applications an adjustment of the controller may be required.

You find the setpoint displayed in figs 59 and 60.

English (GB)

Controller_setting_menu_with_temperature_offset

undef-079undef-080

Fig. 59 "Controller gain Kp"

Fig. 60 "Control. integr. action time Ti"

Proceed as follows:

1. Increase the gain until the motor becomes unstable. Instability can be seen by observing if the measured value starts to fluctuate. Furthermore, instability is audible as the motor starts hunting up and down. Some systems, such as temperature controls, are slow-reacting, meaning that it may be several minutes before the motor becomes unstable.

2. Set the gain to half the value of the value which made the motor unstable.

3. Reduce the integral time until the motor becomes unstable.

4. Set the integral time to twice the value which made the motor unstable.

Rules of thumb

If the controller is too slow-reacting, increase the gain. If the controller is hunting or unstable, dampen the system by

reducing the gain or increasing the integral time. Model A: Use Grundfos GO to change the controller constants, gain and

integral time. You can only set positive values. Models B, C and D: Change the control settings by means of the display or Grundfos

GO. You can set both positive and negative values.

control mode

• pump installed in flow pipe

• system with flow-pipe temperature control.

Temperature influence is suitable for the following systems:

• Systems with variable flows for example two-pipe heating

systems, in which the enabling of the temperature influence function ensures a further reduction of the pump performance in periods with small heating demands and consequently a reduced flow-pipe temperature.

• Systems with almost constant flows, for example one-pipe

heating systems and underfloor heating systems, in which variable heating demands cannot be registered as changes in the head as is the case with two-pipe heating systems. In such systems, you can only adjust the pump performance by enabling the temperature influence function.

Selection of maximum temperature

In systems with a dimensioned flow-pipe temperature:

• Up to and including 55 °C, select a maximum temperature

equal to 50 °C.

• Above 55 °C, select a maximum temperature

You cannot use the temperature influence function in air-conditioning and cooling systems.

Max 0.8 x 4

English (GB)

Before dismantling

WARNING

Electric shock

Death or serious personal injury

- Make sure that other pumps or sources do not force flow through the pump even if the pump is stopped. This will cause the motor to act like a generator, resulting in voltage on the pump.

WARNING

Electric shock

Death or serious personal injury

- Switch off the power supply for at least 3 minutes before you start any work on the product.

- Lock the main switch in position 0. Type and requirements as specified in EN 60204-1, 5.3.2.

WARNING

Magnetic field

Death or serious personal injury

- Persons with pacemakers disassembling this product must exercise care when handling the magnetic materials embedded in the rotor.

9.1 Differential-pressure and temperature sensor

The pump incorporates a differential-pressure and temperature sensor. The sensor is located in the pump housing in a channel between the inlet and outlet ports. The sensors of twin-head pumps are connected to the same channel and the pumps therefore register the same differential pressure and temperature.

Via a cable, the sensor sends an electrical signal for the differential pressure across the pump and for the liquid temperature to the controller in the control box.

If the sensor fails, the pump continues using the last measurement from the sensor and operate based on this. In earlier software versions, model A, the pump runs at maximum speed in case of a sensor fault.

When the fault has been corrected, the pump continues operating according to the parameters set.

The differential-pressure and temperature sensor offers substantial benefits:

• direct feedback on the pump display

• complete pump control

• measurement of the pump load for precise and optimum control resulting in higher energy efficiency.

9.3 Disassembling the plug

11.2.3 Reuse of communication interface modules

You can reuse a communication interface module in a CIU unit used together with Grundfos MAGNA Series 2000 in MAGNA3. Before you use the CIM module in the pump, reconfigure the module. Contact your nearest Grundfos company.

11.2.4 Auto detection of CIM modules

If a pump in a system with multiple pumps is replaced with a newer version (model D), the new pump automatically detects if the existing pump(s) and/or BMS system are older and adjusts itself accordingly.

Auto detection in twin-head pumps happens if one of the pumps is replaced and paired with a newer model than the existing one, i.e. MAGNA3 model D. The new pump automatically detects the model version of the existing pump. If the old pump is an older model, the new pump will adjust itself making it compatible with the old system.

Auto detection can be manually overruled if the system is controlled by a SCADA system. However, when integrating a newer model with an older setup, we recommend that you choose compatibility mode.

For more information on how to manage auto detection directly on the pump, see section "Multipump profile selection", page 45.

11.2.5 Grundfos Remote Management

Grundfos Remote Management is an easy-to-install, low-cost solution for wireless monitoring and management of Grundfos products. It is based on a centrally hosted database and a web server with wireless data collection via GSM or GPRS modem. The system only requires an internet connection, a web browser, a Grundfos Remote Management modem and an antenna as well as a contract with Grundfos allowing you to monitor and manage Grundfos pump systems.

You have wireless access to your account anywhere and anytime you have an internet connection, for example via a mobile device. Warnings and alarms can be sent by e-mail or SMS to your mobile device.
