Installing the temperature sensor

NOTICE:
System damage through damaged capillaries or incorrectly fitted
temperature sensor.
▶ Ensure that the capillaries are neither kinked nor squashed when
uncoiling and routing them.
▶ Always push the temperature sensor right to the bottom of the sensor
pocket.
NOTICE:
System damage due to incorrect sensor position!
The sensors of the high limit safety cut-out (STB) and of the thermostat
(TR) must be fitted at the installation location ( fig. 23, page 24) on
the top of the boiler.
▶ In the case of third party control units, match the sensor immersion
sleeve to the diameter of the sensors used.
▶ Do not change the length of the immersion sleeve.
The boiler test point is at the top of the boiler shell
( fig. 23, [1], page 24).
▶ Measure the depth of the sensor pocket ¾ ".
▶ Mark the depth on the temperature sensor set (cable).
▶ Insert the temperature sensor set as far as it will go into the test
point (to the bottom).
Use the mark to check whether the temperature sensors are correctly
fitted.
▶ Secure the temperature sensor set in the test point with a sensor
retainer [3] ( fig. 22, page 24).
The plastic coil [2] for keeping the temperature sensors together is
pushed back automatically when it is inserted ( fig. 22, page 24).
Insert compensating spring [1] between the temperature sensors to
ensure a good contact between sensor pocket [4] and sensor surfaces,
and thereby a reliable temperature transfer ( fig. 22, page 24).
