A steady green LED (1) is based on the output of the pri-
mary circuit pump (max. output), with longer green
phases (medium output), or with shorter green phases
(low output).

LED (2) indicates the operating status of the circulation
pump (if connected) in the same manner.

A steady green LED (3) indicates that the external
switching output to activate the auxiliary heating (only
disinfection function) is closed.

perature was less than required during the disinfection
time or that the primary circuit temperature fell below
the required temperature level.
