Installing instructions
Installing the sensor(s):
The sensors must be arranged and installed properly for the system to function correctly.
To this end, make sure that they are completely inserted in the immersion sleeves. The
threaded cable connections provided can be used to provide strain relief. The clip-on sensors
must be insulated to protect them from being influenced by the ambient temperature. Water
must be kept out of the immersion sleeves when used outdoors (
damage from freezing
).
In general, the sensors may not be exposed to moisture (such as condensation water),
which might enter the cast resin and damage the sensor. If this happens, heating the sensor
to 90°C for an hour might help. When using immersion sleeves in NIRO tanks (inoxydable) or
pools, pay attention to their
non-corrosion properties
.
Collector sensor (red or black cable with connection box):
Insert either in the tube
directly soldered or riveted to the absorber and sticking out of the collector’s frame or
in a t-shaped connector on the outer collector’s supply line collector tube. Screw an
immersion sleeve with an MS (brass) threaded cable connection (= to protect from
moisture) into this T-shaped connector and insert the sensor. To protect from lighten-
ing, the connection box has parallel overvoltage protection between the sensor and
the extension cable.
Boiler sensor (boiler supply line):
This sensor is either screwed into the boiler with
an immersion sleeve or attached to the boiler’s supply line at a slight distance.
Tank sensor:
The sensor that the solar power system needs should be used with an
immersion sleeve for fin coil heat exchangers just above the exchanger or, if integrat-
ed bare-tube heat exchangers are used, on the lower third of the exchanger or the ex-
changer’s return line so that the immersion sleeve is inside the exchanger’s tube. The
sensor that monitors the heating of the tank from the boiler is installed at the level of
the desired amount of hot water during the heating season. The plastic threaded cable
connections provided can be used to provide strain relief. They must not be installed
below the register / exchanger.
Buffer sensor:
The sensor that the solar power system needs is installed on the bot-
tom of the tank just below the solar heat exchanger using the immersion sleeve pro-
vided. The plastic threaded cable connections provided can be used to provide strain
relief. It is recommended that the sensor be used between the middle and the upper
third of the buffer tank using the immersion sleeve as a reference sensor for the heat-
er’s hydraulics or - flush with the tank’s wall - under the insulation.
Pool sensor (swimming pool):
Put a T-shaped connector on the suction line imme-
diately on the line leading from the pool and screw the sensor in with an immersion
sleeve. In the process, make sure that the material used is non-corroding. Another op-
tion is to put the sensor on the same spot using hose clamps or adhesive tape and to
provide thermal insulation for ambient influences.
Clip-on sensor:
Use pipe clamps, hose clamps, and the like must be attached to the
respective line. Make sure that suitable material is used (corrosion and temperature
resistance, etc.). Then, the sensor has to be well insulated so that the tube tempera-
ture can be taken exactly and influences from the ambient temperature can be ruled
out.
