Product description
The ATAG XL W is a condensing and
modulating gas boiler with one or two
pre-mix burners, which is attached to a
wall. It is characterized by the following
features:
-
A large modulation range that
guarantees a long burner service
life, while minimizing standby
losses, start-up emissions and
material wear-and-tear.
-
Flue gas temperature below 80°C
-
Also suitable for room sealed
conditions
-
Control panel with all operational
elements
-
Microprocessor, with multi-
functional display
-
Automated ignition, with repetition
and ionization monitoring
-
Water pressure monitoring
- Energy-saving
pump
-
Stainless steel heat exchanger
with smooth tube condenser
- Very
maintenance-friendly
-
Ready for weather-dependent
control (accessory)
-
Cascadecontroller up to 8 boilers
-
External controls (accessory) by
RQRႇH%XVRU9
-
Modern metal panelling,
stove-enamelled

performance to the current heating
requirements, by changing the

temperature is continually measured
via a sensor. In case of a deviation
of the actual temperature from the
target temperature, the control unit
reacts immediately and adjusts the
RPM of the fan, and with that the boiler
performance via the gas armature.
A deviation can be due to:
-
A changed default value of the
boiler temperature, via the boiler
heating control unit
-
A change on the outdoor
temperature
-
Request for Domestic Hot Water
-
Changed heating curve
By means of the integration of the
individual components in a system,
and within the control range of the
equipment, it is ensured that the boiler
performance always corresponds to the
actual heating requirements.
