When the operating mode “Off” is activated, all controller functions are switched
off. This can lead, for example, to overheating on the solar collector or other
system components. The measured temperatures continue to be shown to
provide an overview.
This special operating mode is intended only for the fi lling procedure for a
special “Drain Master System” with a fi ll level contact parallel to collector
sensor S1. The instructions on the display must be followed when fi lling
the system. Be sure to terminate the function when fi nished!

the selected parameters are no longer considered. There is a danger of
scalding or serious damage to the system. The operating mode “Manual”
may only be used by specialists for brief function tests or during commis-
sioning!
