Section 1 – General
1.1 INTRODUCTION
This kit is suitable for the Evo S 150.
This manual explains how to install the Pump Control kit and determine the
pump settings.
The Pump control kit converts the demand signal from the boiler pump QX3 mains
voltage output into a Volts Free enable signal for the Grundfos Magna 1 Model
C SELV Start/Stop input signal.
1.2 CONTENTS
This kit includes the following items:

Section 2 – Installation
2.1 PREPARATION
Install the Pump Control kit as follows:
WARNING: Be careful when you install electrical connections. Electric
shock can cause serious injury or death and can cause damage to equipment.
- Make sure that the electrical power supply to the boiler is et to OFF. For safe electrical isolation refer to Gas Safe technical bulletin 118. All work must be carried out by a competent person.
- For access to the control box (refer to refer to manual Evo S INSTALLATION, COMMISSIONING AND SERVICING INSTRUCTIONS Frame 4.6.1).
2.2 INSTALLATION
- Connect the cables from the left-hand side of the relay onto connection QX3, L3, connection 9-brown (live) and connection 10-blue (neutral) on the boiler wiring strip.
- Make sure that the right-hand side cable from the relay goes through the provided cable clamp.
- Insert the relay module into the space between the Mains voltage and PELV installer connection terminals.
2.3 PUMP CONNECTIONS
Mains Voltage Connections 230 VAC
- Connect a suitable 3 core cable between the Boiler and the Pump. 13-Green/Yellow (PE), 14-brown (live) and 15-blue (neutral) on the boiler wiring strip, this provides the permanent supply to the pump.
- Secure the Pump supply cable into the cable clamp at the boiler and the cable retention at the Pump.
In the
supplied Grundfos Installation & Operating instructions refer to ‘Connection
to the power supply, terminal-connected Version’.
For the connection from the relay, refer to the supplied Grundfos installation
and operating instructions ‘Digital input (Start/ Stop)’.
Evo S 150
Hydraulic Configuration| Flow Rate Q (m3/hr) At 20°C| Head (m)| Pump Used
No separation| 6.| 10.| Magna 1 32 – 120F
LLH| 6.| 10.| Magna 1 32 – 120F
PHEX| 6.| 12.| Magna 1 40 – 150F
During the commissioning procedure, to achieve a temperature differential of
20°C at maximum rate, adjust the pump curve following the pump manufacturer’s
instructions.
2.4 OPERATING PANEL
CAUTION: Hot surface – minor or moderate personal injury. To avoid burns,
only touch the operating panel.
The operating panel on the pump comprises of the
following:
| Position | Description |
|---|---|
| 1 | Infrared receiver for Grundfos GO. Plug-connected versions. |
| 2 | Grundfos Eye. Refer to Section 9.1 in the Grundfos Mangal Installation & |
Operating instructions.
3| Infrared receiver for Grundfos GO. Terminal-connected versions.
4| LEDs indicate the control function. Refer to Section 8.2 in the Grundfos
Mangal Installation & Operating instructions.
5| Push-button for selection of a control function
2.5 SETTING THE CONTROL FUNCTION
The pump has nine control functions, refer to section 7 Control Functions in
the Grundfos Magna1 Installation & Operating instructions. Select the control
function by pressing the push-button on the operating panel, see section 2.4
Operating Panel. The control function is indicated by eight different light
fields in the display.
| Position | Description | |
|---|---|---|
| 0 |
Intermediate proportional-pressure curve, referred to as PP2 factory
setting.
1| | Highest proportional-pressure curve, referred to as PP3.
2| | Lowest constant-pressure curve, referred to as CP1.
3| | Intermediate constant-pressure curve, referred to as CP2.
4| | Highest constant-pressure curve, referred to as CP3.
5| | Constant curve III.
6| | Constant curve II.
7| | Constant curve I.
8| | Lowest proportional-pressure curve, referred to as PP1.
2.6 CONTROL FUNCTIONS
Factory setting: Intermediate proportional pressure curve, referred to as PP2.
Proportional-pressure curve (PP1, PP2 or PP3)
Proportional-pressure control adjusts the pump performance to the actual flow
rate demand in the system, but the pump performance follows the selected
performance curve, PP1, PP2 or PP3. See below where PP2 has been
selected.
The selection of
the right proportional-pressure setting depends on the characteristics of the
system in question and the actual flow rate demand. For further information,
refer to section 7.4 Overview of the control functions and 7.5 Selecting
control function in the Grundfos Magna1 Installation & Operating instructions.
Constant-pressure curve (CP1, CP2 or CP3)
Constant-pressure control adjusts the pump performance to the actual flow rate
demand in the system, but the pump performance follows the selected
performance curve, CP1, CP2 or CP3. See below where CP1 has been selected.
The selection
of the right constant-pressure setting depends on the characteristics of the
system in question and the actual flow rate demand.
For further information, refer to section 7.4 Overview of the control
functions and 7.5 Selecting control function in the Grundfos Magna1
Installation & Operating instructions.
Constant curve (I, II or III)
At constant-curve operation, the pump runs at a constant speed, independently
of the actual flow rate demand in the system. The pump performance follows the
selected performance curve, I, II or III. See below where II has been
selected. 
The selection of
the right constant-curve setting depends on the characteristics of the system
in question.
For further information, refer to section 7.4 Overview of the control
functions and 7.5 Selecting control function in the Grundfos Magna1
Installation & Operating instructions.
