1. Introduction

Medium UPM - EU range

This data booklet applies to the Grundfos Medium UPM pump range.

Applications

In a modern heating, cooling and domestic hot water

supply system there are different circuits in which

Medium UPM pumps in different versions can be

placed. A differentiation must be made between the

heating (or cooling) production and the distribution.

On the production side there are some applications

where pumps are used in primary or internal circuits

e.g. for geothermal or solar thermal brine circuits.

The distribution side is often split into two circuits - a

primary and a secondary circuit - in order to keep the

flow and temperature independent from each other. A

heat exchanger, a hydraulic separator or a buffer tank

can be used for this separation.

For some heating generators (e.g. condensing boilers,

heat pumps or district heating) it is important to keep

the return temperature as low as possible. Therefore it

is necessary to keep the right balance between flow in

primary and secondary circuits. Without separator, the

primary pump creates a differential pressure in the

secondary circuits. A generator effect can happen in

the secondary pump, from which Medium UPM pumps

are protected.

The primary pump is mostly integrated into the heating

appliance and controlled via a control signal (e.g.

PWM or BUS) to ensure the optimum operation of the

boiler, for instance.

Introduction

Medium UPM

Fig. 1 Complete domestic heating system combined with renewable energy sources

On the generation side, most pumps are externally

controlled via control signal ( PWM, LIN bus) by the

appliance control. The pumps on the distribution side

are often stand-alone pumps and mainly internally

controlled (AUTO version). The pumps in circuits with

variable flow are differential-pressure controlled either

as constant pressure (CP) or proportional pressure

(PP) control. In addition to 3 different control curves

each, there is the option to select the AUTOADAPT CP

or PP mode. With AUTOADAPT, the control curve is

automatically adapted to the actual requirements of the

respective application.

For domestic hot water systems, we must offer pumps

with stainless-steel housings that have the necessary

drinking water approvals like UBA, KTW, DVGW, ACS,

KIWA or WRAS.

For solar thermal systems, SOLAR PML pumps are

available, which are suitable for solar media containing

glycol up to 110 °C (peak). They use the PWM-C signal

profile, which is inverse of the PWM-A signal profile.

The PWM-C signal profile stops the pump and avoids

that the pump runs and overheats or unloads the

storage tank, if the signal is missing.

All medium UPM pumps are equipped with spacers to

decouple the terminal box from the motor. The motor is

protected against condensate in the stator with drain

holes. Therefore, all pumps can run down to minus

10 °C with antifreeze media mixtures.

ErP, Ecodesign regulation in brief

The EU has addressed the climate challenge in a EuP/

ErP directive: Since August 2015, all stand-alone

pumps as well as pumps integrated in boiler systems,

solar systems and heat pump systems must fulfil

Ecodesign requirements, defined in regulation 641/

2009/EC on glandless pumps, which was amended by

622/2012/EC. The regulation has set radically new

standards for energy efficiency.

The essentials

• Glandless pumps integrated in products must have

an energy efficiency index (EEI) of not more than

0.23. The benchmark level is 0.20.

• Stand-alone pumps are measured according to EN

16297-2.

• Integrated pumps are measured according to EN

16297-3, due to their various functions integrated in

many customised hydraulic solutions on the market.

• All pumps integrated in products which generate

and/or transfer heat and all types of media are

included. This means that not only heating systems,

but also solar-thermal and heat pump systems are

affected by the Ecodesign regulation.

• Non-compliant spare pumps for integrated pumps

sold before August 2015 are allowed until January

1st, 2022.

• Pumps designed for recirculation of drinking water

are out of the scope of this regulation.

• Conformity with EU regulations is governed through

mandatory CE marking.

All Grundfos Medium UPM pumps meet the Ecodesign

requirements measured by EN 16297-2 and EN

16297-3:2012.

Control mode and signals

Medium UPM

5. Control mode and signals

Control principles

Some medium UPM pumps are controlled via a digital

low-voltage pulse-width modulation (PWM) signal,

which means that the speed of rotation depends on the

input signal. The speed changes as a function of the

input profile. These communication signals are

standardised in the VDMA Einheitsblatt 24244 "Wet

runner circulating pumps - Specification of PWM

control signals".

Control signals

Digital low-voltage PWM signal

The square-wave PWM signal is designed for a 100 to

4,000 Hz frequency range. The PWM signal is used to

select the speed (speed command) and as feedback

signal. The PWM frequency on the feedback signal is

fixed at 75 Hz in the pump.

Duty cycle

d % = 100 x t/T

Example

Fig. 4 PWM signal

Interface

The Medium UPM PWM interface consists of an

electronic part connecting the external control signal to

the pump. The interface translates the external signal

into a signal type that the microprocessor can

understand.

In addition, the interface ensures that the user cannot

get into contact with dangerous voltage if touching the

signal wires when power is connected to the pump.

Note: "Signal ref." is a signal reference with no

connection to protective earth.
