Hydraulic connections
Temperature sensor
Each collector has a sleeve for inserting a temperature sensor. The sleeve is directly connected with the absorber. If the
collectors are installed correctly, the sleeve is always located on the top of the collector on the left. The temperature sensor
can be inserted in any collector. Please pay attention to the maximum insertion depth of 4 cm and secure the sensor
against slipping out. Due to the measuring point on the absorber, the temperature measured by the sensor may differ from
the fluid temperature.
Installations with one up to six collectors in one row
Connection F red
Connection BF blue
A or B
C or D
Close unused connections with
caps.
Installations with seven up to 15 collectors in one row
Connection bottom left / top right
BF = C / F = B
Connection top left / bottom right
BF = D / F = A
Close unused connections with
caps.
Connection F A + E / BF H + D
Connection F B + F / BF G + C
Close unused connections with
caps.
In case of multi-row installations as well as installations which include the STI Drain Back System, the
connection pipe must always be connected with the diagonal line to the external manifold (Tichelmann), e.
g. bottom left and top right.
F = Flow (from the collector to the storage) red grommet
BF = Backflow (from the storage to the collector) blue grommet
In case of installing an air eliminator, install it at the opposite end of
the top flow connection!
