Regeneration / drainage valve

The regeneration valve (B) and the drainage valve (C) are situated in
the water softening system.
the water stored in the regeneration chamber is conveyed through the
water softening system (A). If the drainage valve (C) is actuated, the
water stored in the heat exchanger is conveyed into the rinsing tank
via the water softening system (A).

Raw water valve

The raw water valve (D) is located at the rear on the water softening
system (A) and is responsible for admixing hard water.
The raw or soft water valve (D) is actuated via the electronics module
which calculates how frequently and how long the valve is to be
actuated for. As a result, a constant water hardness of approx. 5° dH
is obtained. For this reason it is important to set the hardness range
precisely.
If the valve is actuated (open), the raw water is conveyed through the
water softening system and softened. If the valve is not actuated
(closed), the inlet to the water softening system is sealed and the raw
water flows directly into the heat exchanger via the water inlet.
