1. Installation

1.1. Preparation

Only qualified personnel may install the equipment, following the requirements listed in this document.
More detailed instruction can be found on www.heating.danfoss.com.

Note! This product is approved for ambient temperature between 5-55° C, but to ensure optimal conditions for
battery it is recommended to install Calculator at max. 45° C. Avoid installation stress from pipes and fittings.
Flush the system.

1.2. Identification of installation: Return/Supply pipe installation and flow direction

1.3. Mounting of flow sensor

Pipe position: No limitations but avoid positions

where air can be collected.

Inlet/outlet conditions (only for DN 65-DN 100)
In order to maximize performance it is necessary to have straight inlet and outlet flow conditions before
and after the flow sensor: 5 × DN on inlet and 3 × DN on outlet of flow sensor.

1.4. Mounting and sealing of calculator

Heat meter calculator may be installed in heated premises, working ambient temperature shall
be not more than 55 °C. It may not be exposed to direct sunlight.
The calculator is mounted on an auxiliary holder (it can be oriented in the required direction at an angle of
each 90 °:

The possible ways of the mounting of the calculator (auxiliary holder):

- Direct mounting on the housing of the flow sensor, by turning each 90o (only when the flow temperature
does not exceed 90oC):

Rotation in pipe axis: Flow sensor should be angled
in 45 to 315° to avoid air collection in flow sensor.

Installation guide SonoMeter 30

- On the wall:

- Panel mounting on standard DIN-rail.

- Adapter plate according to figure 8 of EN1434-2:2007 for wall mounting of calculator can be used (if the
aperture in the wall is too large for the calculator):

Important: It is forbidden to attach the calculator directly to a wall if there is a risk that on walls can
be condensed humidity or temperature of a surface of a wall can fall lower than 5°C. In this case, it is
recommended to attach the calculator so that between it and wall surfaces there was an air gap not
less than 5 cm.

1.6. Setting up the jumpers (J)

The connector J is on the calculator plate between the temperature sensors and pulse input / output con­nection terminals (see 6.3). Joining or leaving open the connector contacts, you can choose the normal or
verification (test) mode, activate the pulse inputs or outputs:

Jumper is not set
(contacts are opened)

NORMAL MODE VERIFICATION (TEST) MODE

The first pulse output V1 is active
(terminals 52,53).
Energy as default.

The second pulse output V2 is active
(terminals 50,51).
Volume as default.

Note: On delivery the heat meter is configured with two outputs.

2. Electrical wiring

Wiring diagram 1

Jumper settings:
1: Additional pulse input V2 is on.
2: Additional pulse input V1 is on.

Jumper is set
(contacts are connected)

The first pulse intput V1 is active
(terminals 52,53)
(Jumper must be removed when
operating in TEST mode)

The second pulse intput V2 is active
(terminals 50,51)
(Jumper must be removed when
operating in TEST mode)

T1: flow temperature sensor.
T2: return temperature sensor.
V1: additional pulse input/output 1.
V2: additional pulse input/output 2.
