Service Manual 4.5.3 Regeneration electronics system On comparing the degree of water hardness set in the appliance, the electronics system determines what quantity of water is possible before the water softener is exhausted. The quantity of water used is calculated. Once the subsequent maximum number of rinses has been reached, recovery is carried out. The discharge behaviour of the regeneration electronics system can be seen in the description under initial operation / replacing the electronics unit.

Service Manual Fill system Regeneration with heat exchanger After the fill solenoid is opened, the water flows to the integrated inlet over the free flow line into the softener and then as softened water into the heat exchanger. After the regeneration chamber is filled the water flows through the overflow channel into the thredtle cup of the level sensor.
Page 20
Service Manual Intake of water with heat exchanger After the fill solenoid is opened, the water flows to the integrated inlet over the free flow line into the regeneration chamber. When the regeneration chamber has been filled the water will flow through the overflow channel in the softening equipment and as soft water into the level sensor and the pump cavity.
Page 21
Service Manual Filling procedure for appliances with a heat exchanger The electronic system determines the time between the open command of the fill solenoid and the clo- sing of the level switch (f1). From this time the additional fill time of the fill solenoid is calculated. For every initial fill-up in a rinsing program, 200ml more water than the standard water volume will be filled in.

Service Manual Thermohydraulic system (actuator) The thermohydraulic system comprises a metal cylinder with a push rod. The cylinder is filled with a sub- stance which greatly expands when heated. A PTC serves as a source of heat (Postive Temperature Coefficient), and this makes direct contact with the metal cylinder. Subsequent to switch-off of the heat source, a strong compression spring returns the push rod back to its original position.
Page 24
Service Manual Regeneration, drain-off and raw water valves The regeneration valve and the drain-off valve are located on the softening equipment. When the regeneration valve is activated the volume of water stored in the regeneration chamber is lead through the softening equipment. When the drain-off valve is activated the volume of water stored in the heat exchanger is lead through the softening equipment to the rinsing cavity.
