Product description
THISION S PLUS
Product description
The THISION S PLUS is a condensing
and modulating gas boiler with a pre-
mix burner, 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
- Flue gas temperature fuse
- 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
- Analog manometer
- Energy-saving pump
- Installed safety valve
- Stainless steel heat exchanger with
smooth tube condenser
- Very maintenance-friendly
- Weather-compensated control with
room unit/remote control QAA 55,
or with room unit/remote control
QAA 75/78 (accessory)
- Modern metal panelling, stove-
enamelled
Functional description
The control unit modifies the heating
performance to the current heating
requirements, by changing the
default values of the fan rotating
speed. In this regard, the boiler flow
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 LMS 14
heating control unit
- A change on the outdoor
temperature
- Request for warm water
- Changed heating curve
- Changed volume flow in the heating
system (due to thermostat valves
and mixer)
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.
