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

59.

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.

To ensure adequate 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.

Fig. 18 Warning 77

5. Storing and handling the product

5.1 Frost protection

If the pump is not used during periods of frost, take
the necessary steps to prevent frost bursts.

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

TM05 8894 2813

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 control 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.

2.1.5.1.0.0 6WDWXV

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

Observe local legislation regarding pump housing
material.

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.

English (GB)

Do not pump aggressive liquids.

Do not pump flammable, combustible or explosive
liquids.

13

6.2.1 Glycol

English (GB)

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.

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

The pump can communicate with Grundfos GO and with other

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

6.6 Insulating shells

Insulating shells are available for single-head pumps only.

Limit the heat loss from the pump housing and
pipes.

English (GB)

Reduce the heat loss by insulating the pump housing and the
pipes. See figures 23 and 14.

• 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.

TM05 2859 3216TM05 3055 0912

Fig. 23 Insulating shells

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

6.7 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. 24. This is
especially important in proportional-pressure control mode with
reduced head at low flow.

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. 32.

• 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.

is not exceeded.

LIMIT

. The pump

Recommended for main pumps in boiler applications where a steady flow through the boiler is required. No extra
energy is used for pumping too much liquid into the system.

In systems with mixing loops, you can use the control mode to control the flow in each loop.
Benefits:

• Enough water for all loops at peak load conditions if you have set each loop to the right maximum flow.

• The dimensioned flow for each zone, required heat energy, is determined by the flow from the pump. You can
set this value in the FLOW

control mode without the use of throttling valves.

ADAPT

• When the flow is set lower than the balancing valve setting, the pump ramps down instead of losing energy by
pumping against a balancing valve.

• Cooling surfaces in air-conditioning systems can operate at high pressure and low flow.

Recommended 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 balancing valves
– differential-pressure regulators
– large pressure losses in those parts of the system through which 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.

Recommended in systems with relatively small pressure losses in the distribution pipes.

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

– sized for natural circulation
– small pressure losses in those parts of the system through which the total quantity of water flows, for

example boiler, heat exchanger and distribution pipe up to the first branching or 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.

In heating systems with a fixed system characteristic, for example domestic hot-water systems, it may be
relevant to control the pump according to a constant return-pipe temperature.

You can use FLOW

System application

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.

You can also set the pump to operate according to the maximum or minimum curve, like an uncontrolled pump:

• Use the maximum-curve mode in periods in which a maximum flow is required. This operating mode is for
instance suitable for hot-water priority.

• 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 you do not want automatic night setback.

This control mode ensures a constant temperature. Constant
temperature is a comfort control mode that you can use in
domestic hot-water systems to control the flow to maintain a fixed
temperature in the system. See fig. 39. When you use this control
mode, do not install any balancing valves in the system.

If the pump is installed in the flow pipe, install a temperature
sensor in the return pipe of the system. Install the sensor as close
as possible to the consumer for example a radiator or heat
exchanger.

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 for example a radiator or
heat exchanger.

The constant-temperature control mode also reduces the risk of
bacterial growth in the system, for example legionella.

Sensor range:

• minimum -10 °C

• maximum 130 °C.

To ensure that the pump is able to control the temperature, we
recommend that you set the sensor range between -5 and +125
°C.

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.
Model B and C:
Change the control settings by means of the display or Grundfos

GO. You can set both positive and negative values.

Once you have enabled automatic night setback, the pump
automatically changes between normal duty and night setback,
i.e. duty at low demand. The changeover depends on the
flow-pipe temperature.

The pump automatically changes over 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 a time lag when
the temperature has increased by approximately 10 °C.

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

The temperature influence function requires the following:

• proportional-pressure, constant-pressure or constant-curve
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

TM05 3219 1212

equal to 50 °C.

• Above 55 °C, select a maximum temperature

equal to 80 °C.

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

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 pumps in a multipump system
communicate with each other via the wireless GENIair
connection.

Pump system:

• Twin-head pump.

• Two single-head pumps connected in parallel. The pumps

must be of the same type and size. Each pump requires a
non-return valve in series with the pump.

You can set a multipump system from a selected pump, which will
then be the master pump.

Check the nameplate to identify the master pump. See fig. 52.

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.

When a twin-head pump is running in constant-pressure control
mode, the second pump starts at 90 % of the maximum
performance. The second pump stops automatically when it is no
longer needed to fulfil the system demand. If both pumps are
running, they run at the same speed.

• Set the control mode to "&RQVWSUHVV" or "&RQVWDQWFXUYH".

8.8.4 External connections in a multipump systems

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.

Set the following on both the master and slave pump:

• Relays

From model B. Configure on both master and slave pump.

• Operating mode, control mode and setpoint

These modes are system parameters and they are shared
between the two pumps.

• Heat energy monitor

The heat energy monitor works on the system level.
Therefore, both pumps display the heat energy for the system,
not for the individual pump.

The heat energy monitor is a monitoring function that calculates
the heat energy consumption within a system. The built-in flow
estimation needed for the calculation has an inaccuracy of ± 10 %
of the maximum flow. Also, the temperature measurements
needed for the calculation have some inaccuracy depending 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 caused by
system imbalances.

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

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. 59. Due to the flap valve there is a difference in the hydraulic
between the two pump heads. See fig. 60.

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.

8.14 Wireless GENIair

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:

• Multipump function.

See section 9. Servicing the product.

• Grundfos GO.

See section 11.1 Grundfos GO.

9. Servicing the product

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.

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.

English (GB)

9.2 External sensor condition

In case of missing sensor signal:

• Pumps produced before week 4, 2016: The pump runs at
maximum speed.

• Pumps produced after week 4, 2016: The pump runs at 50 %
of the nominal speed.

In the case of cascade operation, the required relative inlet
pressure must be increased by 0.1 bar / 0.01 MPa compared to
the stated values for single-head pumps or twin-head pumps in
single-head operation.

The relative minimum inlet pressures apply to pumps installed up
to 300 metres above sea level. For altitudes above 300 metres,
the required relative inlet pressure must be increased by 0.01 bar
/ 0.001 MPa per 100 metres altitude. The MAGNA3 pump is only
approved for an altitude of 2000 metres above sea level.

Sound pressure level

The sound pressure level of the pump is lower than 43 dB(A).

Leakage current

The mains filter will cause a leakage current to earth during
operation. The leakage current is less than 3.5 mA.

Consumption when the pump is stopped

4 to 10 W, depending on activity, such as reading the display, use
of Grundfos GO, interaction with modules.

4 W when the pump is stopped and there is no activity.

Power factor

The terminal-connected versions have built-in an active power
factor correction which gives a cos ij from 0.98 to 0.99.

The plug-connected versions have built-in passive PFC, with coil
and resistors which ensures that the current drawn from the grid
is in phase with the voltage. The current is approximately
sinusoidal which gives a cos ij from 0.55 to 0.98.
