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.
