Instructions VX Solo II HWS (ECL 210/A237)
Domestic hot water circulation pump
It is recommended to set the pump at highest speed of rotation (set-
ting 3) before start-up. Then set the pump at lowest possible speed of
rotation (setting 1), in due consideration of the electricity consump-
tion and the heating comfort. Factory setting of the selector switch is
centre position (default).
Select setting 2 and 3 only if the pump setting does not meet actual
system requirements.
