4.2.3 Two heating circuits
The supply of the two heating circuits is fitted to the boiler
supply. The return from heating circuit 2 (lower temperature
level) is connected to the storage tank in accordance with
table 5, but without a switching valve.
The return from heating circuit 1 is connected in accordance
with table 5.

4.2.4 Limiting the boiler return temperature
In boilers or instantaneous water heaters with a maximum
permitted boiler return temperature, the return temperature
can be restricted via a thermostatic mixing valve M.

5 Connections for expanding
capacity
Application, use
Solar heating support for larger systems
Buffering solid fuel boilers
Double capacity for hot water and solar heat exchangers for two SOLUS II
storage tanks.
5.1 Advantages, limits
Simple expansion of the storage tank capacity via
parallel connection with a buffer storage tank
Greater storage tank volume possible even with
restricted access conditions.
Retrofitted connection possible.
5.2 Connection rules
5.2.1 Parallel connection of two SOLUS II storage tanks
(2nd storage tank: standard or buffer module)
All connections connected to the boiler or heating circuit
are joined horizontally
The following connections must always be connected in
parallel, even if no boiler or heating circuit is connected:
BS1, HS, R3
Diameter and length of the connecting pipes:
Max. 0.5 m at 1", max. 1,2 m at 1 1/4"
Otherwise, the storage tank connected in parallel and
buffer are connected in accordance with the connection
rules which apply for SOLUS II storage tanks.
The Solus II 1000 PM is an extension of the Solus II 1000
and can be connected together in parallel.
Attention:
Due to differing heights, connection combination of the
Solus II 1000 PM and the Solus II 1050 l is not possible.
General rules:
The boiler and heating circuit are connected in the middle
with downward siphons to the connection lines.
