• installation and operating instructions.

3. Installing the product

Connect the product to the district heating network in

the valve chamber.

3.1 Location

Install the product in a location that meets the

following requirements:

• Place the product in a flood-safe valve chamber.

• Place the product in a location easily accessible

for inspection, maintenance and service.

3.2 Installation

Hoses purchased separately must as a

minimum meet the pressure and

temperature conditions according to the

installation in question.

WARNING

Falling hazard

Death or serious personal injury

- Initiate work in the valve chamber

according to local regulations.

CAUTION

Crushing of limbs

Minor or moderate personal injury

- Unpack the product in an area with

ample space before placing it in the

valve chamber.

WARNING

Steam

Death or serious personal injury

- Lift the product using the handle.

CAUTION

Crushing of limbs

Minor or moderate personal injury

- Lift the product using the handle.

The product can be placed on all sides

except on the front. We recommend

placing it on the bottom side.

WARNING

Hot surface

Death or serious personal injury

- Before starting any work on the product,

ensure that the district heating pipe has

cooled down.

WARNING

Steam

Death or serious personal injury

- Before starting any out work on the

product, pay attention to the direction of

the connecting branches.

- Ensure that the system has cooled

down before connecting the district

heating pipe.

WARNING

Steam

Death or serious personal injury

- Tighten the stubs to ensure a safe and

correct tightening.

- Insert Y strainers between the flow pipe

and the flow stub labeled "SUPPLY IN"

on the product, and insert Y strainers

between the return pipe and the inlet

stub labeled "RETURN IN" on the

product.

- We recommend using felt gaskets or

similar products designed for use in

district heating water.

The product can be placed on all sides

except on the front. We recommend

placing it on the bottom side.

The connection to "RETURN IN" and

"RETURN OUT" must be carried out so

that "RETURN IN" comes before

"RETURN OUT" in the flow direction. See

fig. 1.

English (GB)

There are 3 connection stubs with 1/2" threads on

the front panel of the product.

1. Connect the stub labeled "SUPPLY IN" to the

flow pipe.

2. Connect the stub labeled "RETURN IN" to the

return pipe.

3. Connect the stub labeled "RETURN OUT" to the

return pipe.

Fig. 1 Connecting to pit measure point

3.3 Throttle valve

The throttle valve is by default set to 3, and the cover

is loosely attached.

3.4 Antenna

Connect the supplied antenna to the antenna

connector labeled "GSM".

For optimal antenna conditions, we recommend

drilling diagonally from the road into the well and

sending the receiving part of the antenna into the

hole. It is important that there is sufficient air around

the receiving part of the antenna, and we therefore

recommend placing the antenna in a conduit. Refill

the hole in the road afterwards. See fig 2.

Fig. 2 Positioning the antenna

TM07 4107 0319

The product is designed for installation in a

humid environment. We recommend

placing the product in the well in order to

minimise the risk of flooding the product in

connection to, for example, heavy rain.

Place the product on, for example, a shelf

or on top of the exposed main lines.

Return pipe

CAUTION

Falling hazard

Minor or moderate personal injury

- Place the antenna cable away from the

walking path.

- Ensure that the antenna cable is fixed

with cabel ties.

CAUTION

Exposure to RF radiation

Minor or moderate personal injury

- After installing the antenna, stay at

minimum 20 cm away from it.

3.6 Finish installation

4. Product introduction

4.1 Product description

The product is used for temperature and pressure

measurement in the district heating network.

Typical applications:

• Valve chambers

• District heating network without access to supply

voltage.

4.2 Intended use

The product is powered by transforming heat to

electricity via a thermoelectric generator that relies

on the temperature difference from one side to the

other.

The product is therefore designed with two inlet

stubs for the flow and return pipe, respectively. The

resulting mixture from the two inlets is released by

the third stub.

Note that an existing PIN code on the SIM

card must be removed.

WARNING

Death or serious personal injury

- Conclude work in the valve chamber

according to local regulations.

4.3 Using the product

View the logged data on the following website:

• http://igrid.grundfos.com.

Logging into the website requires a user name and

password supplied separately by Grundfos.

Once you are logged in, data from the data logging

devices become available by clicking on "My

devices" at the top of the webpage.

You can now click on the following options next to a

device:

• "Graphics"

•"Data"

•"Settings".

The "Graphics" tab is displayed by default.

Graphics

The graphs are designed with the pressure and

temperature curves in separate coordinate systems.

A minimised version of the curves is displayed under

each coordinate system. The required period that the

curves have to span can be set.

Use the slider on the right and left side of the time

interval to narrow or extend the displayed time

period. Alternatively, you can select different zoom

ranges directly from the dropdown menu.

Data

Click "Data" to display the logged data. Data in the

columns are displayed with type designation

depending on the type of unit (for example pit

measure point or bypass cabinet) chosen, for

example T-flow or T-return.

The column with the U-CAP designation indicates

the charged voltage level of the capacitors that act

as an energy storage in TEG-based products. Data

transmission starts at approximately 4 volt.
