Remark!
• Fit the EBC20 and the pressure transducer (XTP) in the boiler room
• Fit the measuring probe(A) in the boiler flue or in the manifold. However, for atmospheric boi-
lers, 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 con-
densate 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 affected by wind, rain, etc. If appropriate, fit 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.
