4.3 Linking several solar storage tanks
The ROTEX-storage tank extension is a system of connecting
lines and permits parallel linking of several hot water storage
tanks for use in the ROTEX solar system.
The solar storage tank extension kit CON SX ( 16 01 20) can
be used to link, per Control and pump unit RPS4, 2 hot water
storage tanks used for solar systems (fig. 4-35). It is possible to
link a maximum of 3 hot water storage tanks to produce a storage
tank battery (solar storage tank extension kit 2 for a third hot
water storage tank - CON SXE ( 16 01 21).
The optional ROTEX FlowGuard FLG ( 16 41 02) ensures
even filling of the linked hot water storage tanks. One FlowGuard
should be installed per hot water storage tank. The FlowSensor
is installed in the common flow (fig. 4-34).
Operating principle
– The solar return is taken from the solar zone of the linked hot
water storage tanks via the return connection line (fig. 4-35,
item 5).
– The common return is pumped to the solar panel array by the
Control and pump unit RPS4 (fig. 4-35, item 4).
– The water is heated in the solar panel array and is directed,
as the solar flow, to the hot water storage tank via the flow dis-
tribution line (fig. 4-35, item 6).
Installation of storage tank extension for 2 hot water
storage tanks
1. Mounting the Control and pump unit RPS4 without fitting the
hood (see section 4.2).
2. Unscrew the covering cap on the solar return connection from
the second solar storage tank.

WARNING!
Danger of scalding by releasing the connection lines
from the storage tank or when working on the
hydraulics on the Control and pump unit (e.g. when
changing a pump).
Ɣ Empty the storage tank (de-pressurised area)
before working on the connecting line or the
hydraulics.
CAUTION!
Large volumes of water may come out of the solar
storage tank during installation.
Ɣ Mount the storage tank extension kit before filling
the hot water storage tank (depressurised range)
with water.
Ɣ If the solar system is to be connected to solar
storage tank that is already in operation, the
depressurised storage area must first be drained.
