The motor circuit breaker interrupts the circuit when the motor is overloaded.

SB MB standard:

If the residual hardness of the softened water exceeds a limit value, the controller calculates the residual capacity of the base exchanger bottle.

The regeneration of the base exchanger bottle is started the following night at the latest.

SB MB comfort:

If the residual hardness of the softened water exceeds a limit value, the regeneration of the base exchanger bottle begins immediately.

If there is a water shortage, the system is stopped to prevent the RO pump from running dry.

Switches off the RO pump when the permeate buffer tank is full.

Switches on the pump RO to produce permeate.

Gives a signal to the system when the buffer tank permeate is empty.

Prevents externally supplied hot water above 60°C from being directed to the high-pressure pumps and damaging them.

In the event of a malfunction, the system switches to an alternative type of water (set by the service technician during commissioning).

Regular maintenance according to the following maintenance plan is fundamental for a safely operating system.
