Landis & Staefa Division 19.04.2001
1 Summary
1.1 Brief description
The ALBATROS controllers described in this documentation are designed for
integration in mass-produced heat generating equipment and offer the following control
choices:
• Single- or 2-stage burner, 1 BMU
• D.h.w. charging pump or diverting valve
• 3-position mixing valve and circulating pump
The range of products comprises several units that are complementary in terms of
application and scope of functions. The controllers have communication capability and
can be combined to form extensive heating systems.
For more detailed information about the generation of LPB systems, refer to “Local
Process Bus (LPB), Basic Documentation, System Engineering“, document no.
CE1P2370E.
1.2 Features
• Heating controller for mixing and / or pump heating circuits with:
− weather-compensated flow temperature control
− weather-compensated flow temperature control with room influence
• 2 separately controlled heating circuits (mixing or pump heating circuits)
• Quick setback and boost heating
• Automatic 24-hour heating limit
• Automatic summer / winter changeover
• Remote operation via digital room unit
• The building's thermal dynamics are taken into consideration
• Automatic adjustment of heating curve to the type of building construction and the
heat demand (provided a room unit is connected)
• Adjustable flow temperature boost with mixing heating circuit
• Floor curing function
1)
• Single- or 2-stage burner
