Outlet:
The outlet is where the hot water from the tank is
extracted to be supplied to the household.
Sensor Ports:
When solar DHW system is set up, the sensors must be
coated with heat transfer paste and inserted through
the cable gland into the appropriate sensor port and
tightened. The top sensor port houses S3 and the
bottom sensor port houses S2.
The Thermann controller requires three sensor leads be
installed into the appropriate sensor ports in the solar
system; this is vital for operation of the solar system.
The first temperature sensor port is located on either
side of the collector manifold. Sensor 1 (S1) must be
connected to the outlet of the manifold (the higher
side). Thermann solar rated tanks come with two
temperature sensor ports. The bottom port connects to
the Sensor 2 (S2), the top port connects to the Sensor
3 (S3) sensor.
Solar Return:
When the solar domestic water heating system is set
up, this port is used for the water line returning from
the solar collectors after being heated. This line does
not require any additional components, but should be
run as short as possible and have continuous fall back
to the solar return port.
Thermann recommends using a three-way ball valve
and drain on the solar return line to allow convenient
system filling and draining.
On the solar return line near the tank port, it is
recommended to include a U-shaped heat trap with an
approximate 25cm dip in the piping configuration to
prevent reverse thermos-siphoning.
ALL STORAGE TANKS INCLUDE A PTRV, WHICH IS
LOCATED IN THE TANK PACKAGING, EITHER IN A
BOX, VERTICAL COLUMN OR ELEMENT COVER.

WHEN SOLAR COLLECTORS ARE NOT BEING
INSTALLED.
PTRV Port:
The PTRV port is where the tank ‘pressure and
temperature relief valve’ is to be installed. All PTRV’s
must be fitted with a copper drain pipe to carry any
discharge to an appropriate drain.
COMMISSIONING
SYSTEM FILLING AND AIR PURGE
After all the plumbing connections have been made,
EHW tank needs to be filled with water and purged of
air.
To fill the system:
1. Open the cold mains line and fill up the tank and
open the hot water outlet or hot water taps.
FOR SYSTEM FILLING AND AIR PURGE PROCEDURE
AS A SOLAR DHW SYSTEM, PLEASE REFER TO THE
THERMANN DOMESTIC SOLAR HOT WATER SYSTEM
INSTALLATION MANUAL.
