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.

1.3. Mounting of flow sensor

Pipe position: No limitations but avoid positions

where air can be collected.

Rotation in pipe axis: Flow sensor should be angled

in 45 to 315° to avoid air collection in flow sensor.

1.4. Mounting and sealing of calculator

Direct mounting on ultrasonic flow sensor housing, turning every 90° (only when the temperature of the

flow does not exceed 90° C):

a) On the flow sensor with a thread connection b) On the flow sensor with flange connection

On the wall:

Panel mounting on standard DIN-rail:

1.6. Setting up the jumpers (J)

The connector J is on the calculator plate between the temperature sensors and pulse input / output con-

nection 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)

Jumper is set

(contacts are connected)

NORMAL MODE VERIFICATION (TEST) MODE

The first pulse output V1 is active

(terminals 52,53).

Energy as default.

The first pulse intput V1 is active

(terminals 52,53)

(Jumper must be removed when

operating in TEST mode)

The second pulse output V2 is active

(terminals 50,51).

Volume as default.

The second pulse intput V2 is active

(terminals 50,51)

(Jumper must be removed when

operating in TEST mode)

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

2. Electrical wiring
