KT-Elektronik SOL3-3
5.2 Storage
The storage is only charged until the maximum allowed temperature is reached. Using
factory default settings, charging the storage already ends at 60°C. Falling below 58°C
would initiate a new charging cycle. If the water is routed to extraction points directly,
there is a scalding danger at higher temperatures. If using additional components –
such as mixing taps – and therefore is no risk, higher storage temperatures can and
should be allowed.
Too high temperatures may cause limescale that can negatively affect the performance
of the heat exchanger.

The controller supports the selective charging of two storages, e.g. a storage tank and a
heating buffer storage. Depending on the achievable and the allowed storage
temperature, the solar heat is lead to the storage by means of a switching valve
respectively two separate pumps. The two (logically existing) storages can also be
realized by using a stratified storage with alternative adapters for thermal layering.

The solar thermal controller SOL3-3 is used to transfer the usable solar energy into the
storage tanks in systems with two storage tanks according to the priority presetting and
the programmed parameters. The scope of application of the saved energy is irrelevant
for this process. Differing from the system variants shown in chapter 4, the domestic
water heating and/or the heating circuit can be feeded by storage tank 1 (with SF1)
and/or storage tank 2 (with SF2). Additional equipment for charge reversal can be also
provided.
