Outside temperature sensor AFS 2
Part no: 165339
Install the outside tempera-
ture sensor on a north or
north-eastern wall behind a
heated room.
Minimum distances:
2.5 m from the ground
1 m to the side of doors
and windows. The outside temperature sensor
should be freely subjected to weather influ-
ences. However, avoid locations above win-
dows, doors and air ducts and those affected
by direct solar irradiation.
Installation:
Pull off the lid. Secure the sensor with the
screw supplied. Insert and connect the sensor
lead. Position the lid again and let it clearly
click into place
Immersion sensor TF 6A
Part no: 165342
Insert the immersion sen-
sor into the appropriate
sensor well of the respec-
tive cylinder. Where no
calorifier is installed, fit the
immersion sensor to the
heat pump return.
Diameter: 6 mm
Length: 1 m
Contact sensor AVF 6
Part no:165341
Installation information:
Thoroughly clean the
pipe.
Apply heat conduction
paste A.
Secure the sensor with
a strap.
With a WPWE, also connect the
source sensor. The source pump will
not be started if this is not done.
Install the contact sensor at the source inlet
of the heat pump.
Insulate the contact sensor against vapour
diffusion to protect against the formation of
condensate.
Order additional sensors separately!
PT1000 immersion sensor
Part no:165818
Collector sensor
Diameter: 6 mm
Length: 1.5 m
The immersion sensor with
the longer silicone lead is
the collector sensor (PT
1000).
The correct connection of the collector sen-
sor (silicone lead) is crucial for the correct
function of a solar heating system. The sensor
on collectors from Stiebel Eltron is installed
on the last collector, viewed in the flow direc-
tion of the heat transfer medium. For this,
install and seal in the collector sensor well on
the collector. Coat the collector sensor with
heat conducting paste and insert into the sen-
sor well tube until it bottoms out.
Provide thermal insulation for the collector
sensor well and the roof outlet, which must be
closed without gap and must be UV resistant.
– SecureGood coupling of the sensor
(only secure contact sensors on straight
pieces of pipe).
– Coat the entire surface with heat con-
ducting paste
– Insulate the contact sensor well
– Apply strain relief to the sensor leads
You can check the correct coupling and con-
nection to the manager under the system
parameter Info Temp. by calling up the respec-
tive temperature value.
