1.1 INTRODUCTION
1.2 CONTENTS
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.

Section 1 - General

1. 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.
2. Make sure that the right-hand side cable from the relay
goes through the provided cable clamp.
3. Insert the relay module into the space between the Mains
voltage and PELV installer connection terminals.
2.1 PREPARATION
2.2 INSTALLATION
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.
1. Make sure that the electrical power supply to the boiler is
set to OFF. For safe electrical isolation refer to Gas Safe
technical bulletin 118. All work must be carried out by a
competent person.
2. For access to the control box (refer to refer to manual
Evo S INSTALLATION, COMMISSIONING AND
SERVICING INSTRUCTIONS Frame 4.6.1).

2.3 PUMP CONNECTIONS
Mains Voltage Connections 230 VAC
1. 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.
2. 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)’.
During the commissioning procedure, to achieve a temperature di󰀨erential
of 20°C at maximum rate, adjust the pump curve following the pump
manufacturer’s instructions.

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 di󰀨erent light elds in the display.

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 ow 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.
PP3
PP2
PP1

The selection of the right proportional-pressure setting
depends on the characteristics of the system in
question and the actual ow 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 ow 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.

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 ow
rate demand in the system. The pump performance
follows the selected performance curve, I, II or III. See
below where II has been selected.
