2. Product information

Description EBC24 (exodraft Boiler Control) is a specially developed control component for constant pressure regulation of chimney draft. Available in two variants:

• EBC24EU01 is suitable for indoor installation

• EBC24EU02 is suitable for outdoor installation

By changing the setup, EBC24 can also:

• Regulate the supply of fresh air to the boiler room (see section 4).

Guide structure

EBC24 can be used either to control exodraft chimney fans or to control supply air fans.

The guide is divided into six sections::

• Section 1. Specications

• Section 2. ”Product Information”.

• Section 3: Settings and Troubleshooting

Section 4: Pressure control of exodraft chimney fans (default setting).

• EBC24 ensures and monitors consistent pressure in the chimney.

• EBC24 can also be used for boiler systems with modulating burners.

• The automation monitors the draft in the chimney, disabling the burner in case of malfunction.

• The automation is designed for both solid fuel boilers, atmospheric gas boilers, and boilers with oil and gas blow torches.

• EBC24 can control a chimney fan directly or indirectly via a frequency converter.

Section 5: Pressure control of supply air fan.

• EBC24 is used for control of a supply air fan.

• EBC24 ensures and monitors consistent pressure in the boiler room.

• The automation monitors the pressure in the boiler room, disabling the burner in case of malfunction.

• EBC24 can control a supply air fan directly or indirectly via a frequency converter.

EBC24

Control of. Fitting procedure Chimney fan

Note!

• Install EBC24EU01 and the pressure transducer (XTP) in the boiler room.

• Fit the measuring probe (A) in the boiler ue or in the manifold. However, for atmospheric boilers, the probe must always be positioned after the draft hood.

• Connect the hose from the measuring probe to the negative terminal on the pressure transducer “B1”.

• When the measuring probe is placed outside, it must be installed in a manner that prevents the formation of condensation or ice. EBC24EU02 comes with a straight measuring probe.

• EBC24 must always be installed where it is protected from wind and weather (rain, snow, etc.)

Ø 6.5

Supply air fan • Install the control and the pressure transducer (XTP) in the boiler room.

• Connect the hose for measuring reference pressure (outdoor atmospheric pressure) to the negative terminal “B1” on the pressure transducer. Run the hose outside the building to a place not exposed to the weather. The open end of the hose may be installed inside a box as described at the top of the next page.

Note! • Particularly when wanting positive pressure* in the chimney / boiler room:

• Connect the hose to the positive terminal on the pressure transducer “B2”.

• EBC24 comes with only 2 m of hose.

Note!

*The default setting of the EBC24 is for negative pressure regulation, but local statutory regulations may require constant positive pressure.

**Do not install the pressure transducer in an airtight enclosure, as it uses the atmospheric pressure for reference..

3120073-UK EBC24

Make sure to position the pressure transducer (XTP) correctly.

Note Do not blow into the valves of the XTP.

For outdoor installation, place the pressure transducer where it is not exposed to the weather. For outdoor installation, the pressure transducer should be placed in a box tted with a hole (Ø2mm) in the bottom. The hole serves to ensure correct reference pressure and prevent water entry

If the pressure transducer is positioned where insects have access to the free end, installing a sinter lter is recommended

2.4 Mechanical installation

The control and the transducer must be installed inside, preferably in the boiler room. The control does not need to be installed in a cabinet.

Do not install the transducer in an airtight enclosure. It uses the boiler room pressure / atmospheric pressure as reference pressure.

The control can be installed directly on the wall or somewhere similar.

Take o the lid. The installation holes are placed under the plastic screws keeping the cover in place. The distance between the control and the transducer should not exceed 100 m.

3. Settings and troubleshooting

3.1 Error codes

Most terminal connections are monitored for correct operation. An LED light indicates operating status. If a light comes on, it is an indication that everything is functioning correctly, while a light going out indicates a problem in the circuit it monitors. In addition, error codes are shown on the display.

The error codes are:

• EBC24 can control a chimney fan directly or indirectly via a frequency converter.

4.2 Functioning

General function

• The automation monitors the draft in the chimney, disabling the burner in case of malfunction (the alarm diode on the EBC24 turns on).

• When the boiler thermostat demands heat, the chimney fan will start at max. voltage.

• When the EBC24 registers sucient chimney draft, the burner is released.

• The EBC24 maintains the set pressure by regulating the voltage. The pressure is shown in the display.

• In the event of insucient venting, the burner will initially be disconnected after 15 seconds. Insucient venting is less than 64% of the set value, corresponding to less than 80% of ow.

• When the boiler turns o, the chimney fan stops as well. It is, however, possible to set a post-purge period for the chimney fan (see page 23). Alternatively, the control system can be connected in a way that keeps the chimney fan running continuously (see page 21).

Light-emitting diodes and output signals

All inputs and outputs are connected to a light-emitting diode for monitoring and servicing of the system (see section

2.9.1 Light-emitting diodes and terminal board, page 17)

EBC24 has 0-10V output signals for control of multiple chimney fans via frequency converters or motor power relays.

4.3 Electrical connection

This work must be performed by a qualied electrician in accordance with locally applicable rules and legislation.

Installation of the supply cable must comply with applicable legislation and regulations. The grounding terminal (

When connecting a pressure transducer (XTP) and frequency converter, shielded cable must be used.

) must always be connected.

Isolation switch

exodraft a/s stresses that according to EU’s Machinery Directive, an isolation switch must be incorporated into the xed installation. The isolation switch is not supplied by exodraft, but is available as an accessory.

4.4 Wiring examples

As a constant pressure regulator for exodraft chimney fans, the EBC24 can be connected to a range of dierent signals. The following pages are wiring examples and illustrate the following:

• 4.4.1 One boiler, page 20

• 4.4.2 One boiler med potential free contact, page 21

• 4.4.3 One boiler and extra monitoring with PDS, page 21

• 4.4.4 One boiler connected to frequency converter, page 23

• 4.4.5 Two boilers with continuous operation of chimney fan, page 24

exodraft recommends contacting the boiler manufacturer for correct connection to the boiler automation.

5. Pressure regulation of supply air fan

5.1 Application

General

• The EBC24 is used to control a supply air fan.

• EBC an control a supply air fan directly or indirectly via a frequency converter.

Positioning

24 cInstall the EBC24 and the pressure transducer (XTP) in the boiler room as described in section 2.2 Fitting, pages 6+7

5.2 Mode of operation

General function

• The EBC24 monitors the pressure in the boiler room and disconnects the burner in the event of errors (the alarm diode on the EBC24 will turn on).

• When the pressure in the boiler room changes, the EBC24 will change the fan speed in order to meet the set point pressure for the boiler room.

• The EBC24 is connected to the boiler system in such a way that when a heating requirement arises, the EBC24 will start the fan, delaying the start of the boilers until the pressure in the boiler room is adequate.

• A safety function ensures that if the pressure in the boiler room is insucient, the EBC22 will shut down the boilers the EBC24 will shut down the boilers, should the pressure in the boiler room become insucient.

5.3 Electrical connection

This work must be performed by a qualied electrician in accordance with locally applicable rules and legislation.

Installation of the supply cable must comply with applicable legislation and regulations. The grounding terminal ( ) must always be connected.

When connecting a pressure transducer (XTP) and frequency converter, shielded cable must be used.

Isolation switch
