Product description
The TRIGON L PLUS is a condensing
andmodulatinggasboilerwithoneor
twopre-mixburners,oorstanding.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-compensated
control (accessory)
- Cascadecontrollerupto8boilers
- Externalcontrols(accessory)by
on/o󰀨,eBusor0-10V
- Modern metal panelling,
stove-enamelled
Functional description
Thecontrolunitmodiestheheating
performance to the current heating
requirements,bychangingthe
default values of the fan rotating
speed.Inthisregard,theboilerow
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ATG
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.
