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 secure it 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 / at the top of
the right
BF = C / F = B
Connection at the top of the left /
bottom right
BF = D / F = A
Multi-row installations
Connection F A + E / B +F
Connection BF G + C / H + D
Close unused connections with caps.
In case of installations in two rows that are smaller than 15 m² the connection pipe can be connected to the extern
manifold in any direction from the bottom or the top. In case of installations with more than two rows or larger than
15 m² the connection pipe must always be connected to the diagonal line to the extern manifold (Tichelmann), e.g.
from botton left to the top of the right.
F=Flow (collector to storage) red grommet
BF=Backflow (storage to collector) blue grommet
In case of installation of an air eliminator, install it at the opposite
end of the top flow connection!
