3.1 Control modes and functions
Variable differential pressure Δp-v (I, II, III)
Recommended for two-pipe heating systems with radiators to reduce the flow noise at hermostatic valves.

The pump reduces the delivery head to half in the case of decreasing volume flow in the pipe network.
Electrical energy saving by adjusting the delivery head to the volume flow requirement and lower flow rates. There are three pre-defined pump curves (I, II, III) to choose from.
Constant differential pressure Δp-c (I, II, III) Recommended for underfloor heating for large-sized pipes or all applications without a variable pipe network curve (e.g. storage charge pumps), as well as single- pipe heating systems with radiators.
The control keeps the set delivery head constant irrespective of the pumped volume flow.
There are three pre-defined pump curves (I, II, III) to choose from.
Constant speed (I, II, III)

Recommended for systems with fixed system resistance requiring a constant volume flow.
The pump runs in three prescribed fixed speed stages (I, II, III).
NOTICE
Factory setting: Constant speed, pump curve III
External control via iPWM signal
The required setpoint/actual value comparison for control is performed by an external controller.
A PWM signal (pulse-width modulation) is fed as a correcting variable to the pump.  The PWM signal generator gives the pump a periodic sequence of impulses (the duty cycle) in accordance with DIN IEC 60469-1.
iPWM 1 mode (heating application):
In iPWM 1 mode, the pump speed is controlled according to the PWM input signal.
Behaviour in the event of a cable break: If the signal cable is disconnected from the pump, e.g. due to a cable break, the pump accelerates to maximum speed. PWM signal input [%]

iPWM 2 mode:
In iPWM 2 mode, the pump speed is controlled according to the PWM input signal.
Behaviour in the event of a cable break: If the signal cable is disconnected from the pump, e.g. due to a cable break, the pump stops. PWM signal input [%]

Venting
The pump venting function is activated by pressing and holding the operating button (for 3 seconds) and automatically vents the pump.
However, this function does not vent the heating system.
Manual restart
A manual restart is initiated by pressing and holding the operating button (for 5 seconds) and unblocks the pump as required (e.g. after a long idle time in the summer).
Lock/unlock the button
The key lock is activated by pressing and holding the operating button (for 8 seconds) and locks the pump’s current settings. It protects against undesired or unauthorised adjustment of the pump.
Activating factory setting
The factory setting is activated by pressing and holding the operating button whilst switching off the pump. When the pump is switched on again, the pump runs using the factory settings (delivery condition).

Intended use

High-efficiency circulators in the Wilo-Para series are exclusively intended for circulating fluids in hot-water heating systems and similar systems with constantly changing volume flows.
Permitted fluids:

• Heating water according to VDI 2035 (CH: SWKI BT 102-01).

• Water-glycol mixtures* with a maximum of 50% glycol.

• Glycol has a higher viscosity than water. If admixtures of glycol are used, the pumping data of the pump must be corrected to match the mixing ratio.
  NOTICE
  Only introduce ready-to-use mixtures to the system. The pump must not be used to mix fluid in the system.
  Intended use includes observing these instructions and the specifications and markings on the pump.
  Misuse Any use beyond the intended use is considered misuse and will void any warranty claims.
  WARNING!
  Danger of injury or material damage from improper use!

  • Never use non-specified fluids.
  • Never allow unauthorised persons to carry out work.
  • Never operate the pump beyond the specified limits of use.
  • Never carry out unauthorised conversions.
  • Use authorised accessories only.
  • Never operate with phase angle control.

Installation and electrical connection

6.1 Installation
May only be installed by qualified technicians.
WARNING!
Risk of burns from hot surfaces!
Pump housing (1) and glandless motor (2) may become hot and cause burns if touched.

• During operation, only touch the control module (5).
• Allow the pump to cool down before commencing any work.

WARNING!
Risk of scalding from hot fluids!
Hot fluids can cause scalding. Before installing or removing the pump, or loosening the housing screws (4), note the following:

• Allow the heating system to cool down completely.
• Close shut-off devices or drain the heating system.

Preparation Installation within a building:

• Install the pump in a dry, well-ventilated, frost-free room.

Installation outside a building (outdoor installation):

• Install the pump in a chamber with cover or in a cabinet/housing as weather protection.
• Avoid exposure of the pump to direct sunlight.
•  Protect the pump against rain.
• Keep the motor and electronics continually ventilated to avoid overheating.
•  The permitted fluid temperatures and ambient tem- peratures should not be exceeded or undershot.
•  Choose an installation point that is as easily accessible as possible.
•  Observe the pump’s permitted installation position (Fig. 2).

CAUTION!
An incorrect installation position may damage the pump.

• Select the installation point in line with the permis- sible installation position (Fig. 2).
•  The motor must always be installed horizontally.
•  The electrical connection must never face upwards.
• Install shut-off devices upstream and downstream of the pump to facilitate pump replacement.

CAUTION!
Leaking water may damage the control module.

• Align the upper shut-off device so that leaking water cannot drip onto the control module (5).
•  If the control module is sprayed with liquid, the surface must be dried off.
• Align the upper shut-off device laterally.
• When installing in the feed of open systems, the safety supply must branch off upstream of the pump (EN 12828).
• Complete all welding and brazing work.
• Flush the pipe system.
• Do not use the pump to flush the pipe system.

Installing the pump
Observe the following points when installing the pump:

• Note the direction arrow on the pump housing (1).
•  Install glandless motor (2) horizontally, without mechanical tension.
• Place gaskets in the screwed connections.
• Screw on threaded pipe unions.
•  Use an open-end wrench to secure the pump against twisting and screw tightly to piping.
• Re-mount the thermal insulation shell if required.

CAUTION!
Insufficient heat dissipation and condensation water may damage the control module and the glandless motor.

• Do not thermally insulate the glandless motor (2).
• Ensure all condensate drain openings (3) are kept free.

WARNING!
Risk of fatal injury from magnetic field!
Risk of fatal injury for people with medical implants due to permanent magnets installed in the pump.

• The motor must never be removed.

6.2 Electrical connection
The electrical connection may only be carried out by a qualified electrician.
DANGER!
Risk of fatal injury from electrical voltage!
Immediate risk of fatal injury if live components are touched.

• Before commencing work, switch off the power sup- ply and secure it from being switched on again.
• Never open the control module (5) and never remove operating elements.

CAUTION!
Pulsed mains voltage can cause damage to electronic components.

• Never operate the pump with phase angle control.
•  For applications where it is not clear whether the pump is operated with pulsed voltage, get the control/system manufacturer to confirm that the pump is operated with sinusoidal AC voltage.
•  Switching the pump on/off via triacs/solid-state relays must be examined on a case-by-case basis.

Preparation

• The current type and voltage must correspond to the specifications on the rating plate (6).
•  Maximum back-up fuse: 10 A, slow-blow.
•  Only operate the pump with sinusoidal AC voltage.
•  Note the switching frequency: – On/off switching operations via mains voltage ≤ 100/24 h. – ≤ 20/h for a switching frequency of 1 min. between switching on/off via mains voltage.
•  The electrical connection must be made via a fixed connecting cable equipped with a connector device or an all-pole switch with a contact opening width of at least 3 mm (VDE 0700/Part 1).
•  Use a connecting cable with sufficient outer diameter (e.g. H05VV-F3G1.5) to protect against leaking water and to ensure strain relief on the threaded cable connection.
•  Use a heat-resistant connecting cable where fluid temperatures exceed 90 °C.
•  Ensure that the connecting cable does not make contact with either the pipes or the pump.
