1. Product information
Description
The EBC20 (exodraft Boiler Control) is a specially designed control component for constant pressure regulation of
chimney draft. The EBC20 comes in two versions:
• EBC20EU01 for indoor installation
• EBC20EU02 for outdoor installation
By changing the operating mode, the EBC20 can also:
• Act as a 2-stage speed regulator (see section 3).
• Control the supply of fresh air to the boiler room (see section 4).
Layout of the instructions
The EBC20 can control an exodraft chimney fan or an exodraft supply air fan.
There are seven sections to the instructions:
• Read section 1. ”Product information”.
• Read the section that deals with the required control methods:
Section 2: Pressure-controlled regulation of exodraft fans (factory-set).
Section 3: Two-step speed regulation of exodraft fans.
Section 4: Pressure-controlled regulation of exodraft supply air fan.
• Read sections 5–7.
Section 2,3, and 4 deals with the following:
Section 2: Pressure-controlled regulation of exodraft chimney fans (default).
• The EBC20 ensures and monitors constant pressure in a chimney.
• The EBC20 is designed for use with boiler systems with 1- and 2-stage burners.
• The EBC20 can also be used for boiler systems with modulating burners.
• The control system monitors chimney draft and shuts down the burner in the event of errors (the alarm-
diode on the EBC20 will turn on).
• The control system is intended for both solid fuel boilers, atmospheric gas boilers, condens and forced
draft boilers for oil and gas.
• The EBC20 can control a chimney fan directly or indirectly via a frequency converter.
Section 3: 2-stage speed regulation of exodraft chimney fans.
• The EBC20 can be used as a 2-stage speed regulator for exodraft chimney fans.
• The EBC20 monitors chimney draft and shuts down the burner in the event of errors (the alarmdiode on
the EBC20 will turn on).
• The control system is intended for 1- or 2-stage atmospheric gas boilers.
• The EBC20 can control a chimney fan directly or indirectly via a frequency converter.
Section 4: Pressure-controlled regulation of exodraft supply air fans.
• The EBC20 can be used to control an exodraft BESB or BESF box fan.
• The EBC20 ensures and monitors constant pressure in a boiler room.
• The control system monitors the pressure in the boiler room and shuts down the burner in the event of
errors (the alarmdiode on the EBC20 will turn on).
• The EBC20 can control a supply air fan directly or indirectly via a frequency converter.

Remark!
• Fit the EBC20 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 mounted in a way that prevents condensate or ice from being formed. A straight probe is delivered with the EBC20EU02
• The EBC20EU should be mounted in a way that protects it against rain/snow
Supply air fan • Fit the EBC20 and 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
that is not aected by wind, rain, etc. If appropriate, t the free end of the hose in a box as
described at the top of the next page
Note Special aspects if you require positive pressure* in the chimney/boiler room:
• Connect the hose to the positive terminal on the pressure transducer ”B2”
• In menu 16 (see page 13) set the value to 2 (positive pressure). For operation of the service
menu, see page 12
• Please note that the EBC20 is supplied with only 2 m of hose
NB!
*The default setting of the EBC20 is for negative pressure regulation, but local authority requirements
may state that positive pressure must be maintained.
The pressure transducer cannot be mounted inside an air tight enclosure. It uses the atmospheric
pressure as reference pressure.
3002878-EBC20-UK
6 • Product information6 • Product information
Make sure to position the pressure transducer the right way up.
NB
Do not blow into the valves on the XTP.
Outdoor tting of the pressure transducer (XTP)
When tting the pressure transducer outdoors, make sure to position it in a place where it is not aected by
wind, rain, etc. When tted outdoors, the pressure transducer should ideally be positioned in a box with a hole
(dia. 2 mm) in the bottom. The purpose of this box is to assure correct reference pressure – through the hole –
and to keep water out.
If the pressure transducer is positioned in a place where insects have access to the free end, tting a sinter lter is
recommended.
