1. Introduction
Dear customer, Dear heating technician,
The controller Lambda-Control 1
plus
is the result of many years of research and resultant knowledge of Logotherm. It contains the
latest innovations in combustion and system technology and offers the highest level of quality and perfection.
Numerous of Lambda-Control 1
plus
´s automatic functions are unique new developments by our company. This system fundamentally
operates by automatically “learning” and “gathering” pertinent characteristics of your heating system and its operating methods.
This information is then used to calculate the optimal settings resulting in the highest level of comfort and efficiency, an
extraordinary eco-friendliness and last but not least in a significant reduction of energy costs.
Alongside with other functions, the fuel consumption calculation (BSB) when firing or refuelling the system and the combustion and
burnout optimisation (AAO) are the most significant developments.
