1.1 INTRODUCTION
1.2 CONTENTS
This kit is suitable for the following boilers:
Evo S range of boilers utilising the Grundfos UPMXXL
25-120 pump.
This manual explains how to wire the pump leads to the
installer wiring connections and determine the pump
settings within the boiler control.
The Pump is powered by a 230 V auxillary supply
within the boiler, and controlled by a PWM signal.

Section 1 - General

Install the pump electrical connections as follows (refer to Figure 1).
1. Mains power connections 13 earth, 14 live and 15 neutral.
2. PWM connections 37 ground (Blue) and 38 PWM (Brown) signal,
the remaining Black wire should be taped back or removed.
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 manual ACV Evo S INSTALLATION,
COMMISSIONING AND SERVICING INSTRUCTIONS Frame 4.6.1).

Table 7 - Standalone Boiler
The process to determine the settings for a modulating boiler pump is dependent upon
the hydraulic properties of the installation. For setting of the minimum pump speed the
worst-case ow rate of the system should be set, this must be above the minimum ow
rate allowed by the boiler model. This will ensure that the minimum speed setting cannot
result in a ow rate lower than the minimum ow rate for the boiler model.
The table above shows the initial settings, these can then be adjusted to ensure that
the system ow meets the boiler model requirement. The actual value of the ow
through the boiler can be read from the boiler HMI under ‘Diagnostics heat generation’
8366, also by pressing the ‘I’ information button. The value is shown in l/m. So nal
adjustments can be made to ensure compliance.
