Control of... Fitting procedure
Chimney fan • Fit the EBC22 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 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 (B”1”).
• When the measuring probe is placed outside it must be mounted in a way that prevents condence or ice to
be formed. EBC22EU02 is delivered with a straight measuring probe. If necessary the probe delivered with
EBC20EU01 can be straigtened and placed so the condens can run out.
• EBC20 must always be mounted in a way that protects it from the weather (Rain, snow etc.).
Supply air fan • Fit the EBC22 and pressure transducer (XTP) in the boiler room.
• Connect the hose for measuring reference pressure (outdoor atmospheric pressure) to the negative termi -
nal (B”1”) 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 (B”2”)
• In menu 16 (see page 20) set the value to 2 (positive pressure). For operation of the service menu, see
page 19
• Please note that the EBC22 is supplied with only 2 m of hose.
*The default setting of the EBC22 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.
