Functional description
Thecontrolunitmodiestheheating
performance to the current heating
requirements of the heating system,
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 LMS 14
heating control unit
- A change on the outdoor
temperature
- Request for warm water
- Changed heating curve
- Changedvolumeow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.
