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.
