3 Description and function

3.1 Intended use

The circulators in this series are designed for warm water heating systems and similar systems with constantly changing flows.

The approved fluids are heating water in accordance with VDI 2035, and water/glycol mixture at a mixing ratio of 1:1.

If glycol is added, the delivery data of the pump must be corrected according to the higher viscosity depending on the mixing ratio.

Intended use includes the observation of these instructions as well as of specifications and labelling on the pump.

Any other use is regarded as improper use.

3.2 Product description

The pump (Fig. 1/1) consists of a hydraulic system, a glandless motor with a permanent magnet rotor, and an electronic control module with integrated frequency converter.

The control module has both an operating button together and an LED display (Fig. 1/2) for setting all parameters and for displaying the current power consumption in W.

3.3 Functions

All functions can be set, activated, or deactivated using the operating button.

When in operating mode, the current power consumption in W is displayed.

When the button is turned, the LED display shows the delivery head in "m"

or the speed stage.

Control modes

Variable differential pressure ( p-v ):

If the volume flow in the pipe network decreases, the pump reduces the delivery head by half (Fig. 2a).

Constant differential pressure ( p-c ):

The control keeps the set delivery head constant irrespective of the volume flow delivered (Fig. 2b).

c1, c2, c3

3 speed stages (c1, c2, c3):

The pump runs uncontrolled in three prescribed fixed speed stages (Fig. 2c).

4 Installation and electrical connection

4.1 Installation

DANGER: Before starting work, make sure that the pump is disconnected from the power supply.

Installation site

- Provide a weatherproof, frost-free, dust-free, and well-ventilated room for the installation. Choose an easily accessible installation site.

- Prepare the installation site so that the pump can be installed without being subjected to mechanical stresses. If necessary, support or secure piping on both sides of the pump.

NOTICE: Provide shut-off devices upstream and downstream of the pump to facilitate potential future pump replacement. Perform the installation in a way that prevents leaking water from dripping onto the control module. To do this, align the upper gate valve laterally if necessary.

- Complete all welding and soldering work near the pump prior to the installation of the pump.

CAUTION: Dirt can cause the pump to fail. Flush the pipe system before installation.

- Choose the correct installation position, with the pump motor in a horizontal position, from only the positions shown in (Fig. 3). Direction arrows on the pump housing indicate the direction of flow.

- If heat insulation work is necessary, only the pump housing may be insulated. The pump motor, module, and condensate drainage openings must remain uncovered.

Turning the motor head

If the installation position of the module is changed, the motor housing must be turned as follows:

• Loosen the interior hexagonal head screws.
• Turn the motor housing, including the control module.

NOTICE: In general, turn the motor head before the system is filled. When turning the motor head in a system that has already been filled, do not pull the motor head out of the pump housing. Turn the motor head with a small amount of pressure on the motor unit so that no water can come out of the pump.

CAUTION: Do not damage the housing seal.

Replace damaged gaskets.

- Turn the motor head in such a way that the plug corresponds to the permitted installation position (Fig. 3).

CAUTION: If the position is wrong, water can penetrate and destroy the pump.

- Tighten the interior hexagonal head screws again.

4.2 Electrical connection

DANGER: Work on the electrical connection must be performed only by a qualified electrician and in accordance with national and local regulations.

Before making the connection, ensure that the connecting cable is not live.

• The mains voltage and current type must correspond to the rating plate specifications.

• Connect the plug (Fig. 4a to 4e).

• Mains connection: L, N, PE.

• Max. back-up fuse: 10 A, slow-blow.
• Earth the pump in accordance with instructions.

Dismantle the plug in accordance with Fig. 5. A screwdriver is required to do this.

• The electrical connection is to be established 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.
• To ensure drip protection and strain relief at the PG screwed connection, a connecting cable with an adequate outer diameter is required (e.g. H05VV-F3G1.5).

• For pumps in systems with water temperatures above 90 °C, install a suitably heat-resistant connecting cable.

• The connecting cable is to be laid in such a way that it can under no circumstances come into contact with the pipe and/or the pump and motor housing.

• The switching of the pump using triacs / solid-state relays must be tested on a case-by-case basis.

CAUTION: Voltage pulsing during phase angle control or external control can cause damage to electronic components.

- Only operate the pump with sinusoidal AC voltage as stated on the rating plate.

- The switching of the pump using triacs / solid-state relays must be tested on a case-by-case basis.

5 Commissioning/operation

WARNING: Depending on the pump or the system operating conditions (fluid temperature), the entire pump can become very hot. There is a risk of burns upon coming into contact with the pump! Commissioning by qualified personnel only!

5.1 Operation

The pump is operated using the operating button.

Turning

Selection of the control mode and setting of the delivery head or speed stage.

5.2 Venting

• Fill and vent the system appropriately.
• The pump rotor space vents automatically after a short time in operation. This may cause noises. If necessary, switch off and on again repeatedly to speed up the venting process. The pump will not be harmed by dry running for short periods.

5.3 Setting the pump

By turning the button, the control mode symbol can be selected and the desired delivery head or speed stage set.

Selecting the control mode

Variable differential pressure ( p-v ): see also Fig. 2a The pump is continuously adjusted within the p-v control mode.

Variable differential pressure ( p-c ): see also Fig. 2b The pump is continuously adjusted within the p-c control mode.

c1, c2, c3

3 speed stages: see also Fig. 2c

The pump is set at a fixed speed within the 3 speed stages control mode.

NOTICE: If a standard heating pump is replaced with this high-efficiency pump, the button can be set on the first, second, or third characteristic curve (c1, c2, c3) on the 3 speed stages scale as a reference point for adjusting the pump set-point.

Setting the delivery head / speed stage

The setpoints / speed stages can be increased or decreased by turning the button to the left or right within the selected control mode. In the p-v or p-c control mode, the setting can be carried out in 0.1 m steps.

When the button is turned in the p-v or p-c control mode, the display changes to the set pump setpoint. The “m” symbol will light up.

In the 3 speed stages mode, c1, c2, or c3 is shown for the relevant pump characteristic curve.
