4Display11 Motor
5Control element (3control buttons)12 Suction nozzle

7Connection to power supply (plug-
type connector)
Design The pump is designed with a radial fluid inlet (suction nozzle) and a radial outlet
(discharge nozzle) arranged on the same axis. The impeller is rigidly connected to the
motor shaft. Mechanical sealing is not required as the rotating assembly is completely
isolated from the stator winding. The rotating assembly is lubricated and cooled by
the fluid handled. The motor housing is equipped with a plug-type connector. The
lubricating system and high-quality ceramic bearings ensure smooth running and a
long service life. The integrated continuously variable differential pressure control
and operating software enable an optimum adjustment of the pump to changing
operating conditions and minimise operating costs. The combination of an efficient
hydraulic system with a high-efficiency electric motor makes sure that the input
power is converted into hydraulic energy as efficiently as possible.
Function The fluid enters the pump via the suction nozzle (12) and is accelerated outward in a
cylindrical flow by the rotating impeller (10). In the flow passage of the pump casing
the kinetic energy of the fluid is converted into pressure. The fluid is pumped to the
discharge nozzle (8), where it leaves the pump. The shaft runs in radial plain bearings
(9), which are supported by the motor (11).

6.3 Shutdown
6.3.1 Measures to be taken for shutdown
The pump (set) remains installed
ü Sufficient fluid is supplied for the functional check run of the pump.
1. For prolonged shutdown periods, start up the pump (set) regularly between
once a month and once every three months for approximately five minutes.
ð This will prevent the formation of deposits within the pump and the pump
intake area.
The pump (set) is removed from the pipe and stored
ü The pump has been drained properly (ðSection8.2,Page37) and the safety
instructions for dismantling the pump have been observed.
1. Observe any additional instructions and information provided.
(ðSection3,Page11)
6.3.2 Shutdown
ü The shut-off element in the suction line is and remains open.
1. Close the shut-off element in the discharge line.
2. Switch off the motor and make sure the pump set runs down smoothly to a
standstill.
NOTE
If the discharge line is equipped with a non-return or check valve, the shut-off
element may remain open provided that the system conditions and system
regulations are considered and observed.
For prolonged shutdown periods:
1. Close the shut-off element in the suction line.
CAUTION
Risk of freezing during prolonged pump shutdown periods
Damage to the pump!
▷ Drain the pump and the cooling/heating chambers (if any) or otherwise protect
them against freezing.
6.4 Returning to service
WARNING
Failure to re-install or re-activate protective devices
Risk of injury from moving parts or escaping fluid!
▷ As soon as the work is completed, properly re-install and re-activate any safety-
relevant devices and protective devices.
For returning the equipment to service, observe the sections on commissioning/startup (ðSection6.1,Page22) and the operating limits (ðSection6.2,Page23) .
In addition, carry out all servicing/maintenance operations before returning the
pump (set) to service. (ðSection8,Page36)

7.2 Mode of operation
7.2.1 Information on settings
For common applications such as two-pipe systems Proportional-pressure Control
(Δp-v) is the recommended operating mode. This operating mode offers an extended
control range with additional potential savings compared to Constant-pressure
Control (Δp-c). Depending on the balancing of branch circuits, undersupply may
occur at a consumer installation.
Constant-pressure Control operating mode (Δp‐c) can optionally be selected for
underfloor heating systems, for example. If noises are audible at low flow rates,
select the Proportional-pressure Control operating mode (Δp-v).
The setting of the head setpoint depends on the piping curve of the system and on
the heat requirements. As standard the pump set is pre-set to Proportional-pressure
Control (Δp-v) operating mode.

7.3 Functions
7.3.1 Setback operation
Function
If the Setback Operation function is enabled, the pump set identifies minimum heat
demand when the fluid temperature sinks continuously. The pump set automatically
reduces the setpoint by 30%. When heat demand rises again, the pump set reverts
to its previous setpoint. For applications with small differences between supply
temperature and return temperature disabling the Setback Operation is
recommended (e.g. for underfloor heating systems combined with condensing
boilers or heat pumps).
The pump set switches to night mode (setback operation) when:
▪ The fluid temperature sinks by 20°C within 2hours.
The pump set reverts to day mode when:
▪ The fluid temperature rises by 10°C.
▪ The pump set has been in night mode for more than 7hours.
The figure below illustrates an example of the criteria used by the boiler and pump
set to switch between day mode and night mode:
