2 MAGNA3 Communication • AUTOADAPT (factory setting) which is suitable for most installations. • FLOWADAPT in systems where flow limitation is required. • Proportional-pressure control in systems with considerable pressure losses in relation to large flow variations. • Constant-pressure control in systems with insignificant pressure losses in relation to large flow variations. • Constant-temperature control in systems with a fixed system characteristic, for example domestic hot-water systems.

3 MAGNA3 System applications 3. Air handling unit 7. Underfloor/ceiling Constant flow In these systems the flow will vary depending on how many rooms are in operation. However, since the distance is short between the pump and manifold, to which the pipes are connected, there is no variation in pressure losses. Because of this the constant-pressure control mode is the optimum choice. See Constant pressure, page 19.

3 MAGNA3 System applications 4B. Primary/secondary system, secondary pump Secondary pumps are exposed to large variations in flow and pressure losses due to load variations in the system. For this reason, proportional pressure is the recommended control mode. If the pressure losses are below 5 mWc, the constant pressure control mode is a good alternative.
3 MAGNA3 1 2 3. Ground loop System applications Ground source heat pump systems (GSHP) Since the ground loop is a closed system with no variations in flow, the most suitable control modes are constant flow and constant curve.

4 MAGNA3 Functions 4.
4 MAGNA3 Functions Control modes: Quick overview H AUTOADAPT • We recommend this control mode for most heating systems. • During operation, the pump automatically makes the necessary adjustment to the actual system characteristic. Hset1 A1 Hauto_min A3 A2 Hset2 Q H 25 % Q max 90 % Q max FLOWADAPT The FLOWADAPT control mode combines a control mode and a function: • The pump is running in AUTOADAPT. • The delivered flow from the pump will never exceed a selected FLOWLIMIT.
4 MAGNA3 Functions H Δt Differential temperature • Ensures a constant differential temperature drop across heating and cooling systems. • The pump will maintain a constant differential temperature between the pump and the external sensor. Q H Constant flow Note: Available for pumps with production code from 1838. • The pump maintains a constant flow in the system independently of the head. • It is not possible to use an external sensor, instead, the pump uses its internal sensor.
4 MAGNA3 Operating modes Functions AUTOADAPT We recommend the AUTOADAPT control mode for most heating systems, especially in systems with relatively large pressure losses in the distribution pipes, and in replacement situations where the proportional-pressure duty point is unknown. This control mode has been developed specifically for heating systems and we do not recommend it for air-conditioning and cooling systems. Normal The pump runs according to the selected control mode.
4 MAGNA3 The FLOWADAPT control mode combines AUTOADAPT and FLOWLIMIT, meaning that the pump runs AUTOADAPT while at the same time ensuring that the flow rate never exceeds the entered FLOWLIMIT value. This control mode is suitable for systems where a maximum flow limit is desired and where a steady flow through the boiler in a boiler system is required. Here, no extra energy is used for pumping too much liquid into the system.
4 Proportional pressure Constant 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 the parts of the system through which the entire amount of water flows, for example a boiler, heat exchang
4 MAGNA3 This control mode is suitable in systems with a fixed system characteristic, for example domestic hot-water systems, where the control of the pump according to a constant return-pipe temperature is relevant. The pump is from factory set to operate in a heating system with a controller gain, Kp, equal to 1. If the pump operates in a cooling system, the gain must be changed to a negative value, for example -1. This is done via the operating panel of the pump.
4 Temperature sensor Constant curve To measure the temperature difference of the flow pipe and the 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. 24.
4 MAGNA3 H Limited max. curve % % 30 90% n. Q Speed setting from 0 to 100 % TM05 4266 2212 % Mi Fig. 27 Power and pressure limitations influencing the maximum curve You can also set the pump to operate according to the maximum or minimum curve, like an uncontrolled pump: • You can use the maximum curve mode in periods where a maximum flow rate is required. This operating mode is for instance suitable for hot-water priority.
4 MAGNA3 Hset FLOWLIMIT duty point Hset 2 Q MJNJU Fig. 29 Proportional-pressure control with FLOWLIMIT Hset Normal constant-pressure duty point Q MJNJU Fig. 30 Constant-pressure control with FLOWLIMIT H 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 rooms with underfloor heating because of the regulating inertia of the underfloor heating.
4 MAGNA3 Multipump function The multipump function enables 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 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.

4 Relay outputs Analog input for an external sensor The pump has two signal relays with a potential-free changeover contact for external fault indication. You can set the function of the signal relay to Alarm, Ready or Operation on the pump operating panel or with Grundfos GO.
4 MAGNA3 Functions The electrical signal for the input can be 0-10 V or 4-20 mA. You can change the selection of the electrical signal (0-10 V or 4-20 mA) on the operating panel or with Grundfos GO. External control system The analog input can be used for an external signal for the control from a BMS system or similar control system. BMS signal sensor PLC 24V TM05 2888 0612 Vcc TM05 3221 1112 IN 24V Fig. 41 Analog input for an external sensor or control Max.
4 External setpoint function Linear with Stop 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. Note: Available for pumps with production code from 1838. Here, if the input signal is below 10 %, the pump changes to operating mode "Stop".
