Setting The Collecting Tank Height (Only Rmq A) - Grundfos RMQ A Instrucciones De Instalación Y Funcionamiento

9.2 Setting the collecting tank height (only
RMQ A)
The height is the distance from the bottom of the
tank to the overflow.
Setting the collecting tank height on the operating
panel is only necessary if you require exact display
indication of the water level.
The RMQ unit operates independently of this setting
as the system automatically switches to mains-water
supply when the water level in the collecting tank is
approximately 0.3 m.
The unit can be set to display the correct water level
in the collecting tank. The setting can be made using
a screwdriver. See fig. 14.
