6.3.3 Changing the storage tank temperature sensor
The storage tank temperature sensor is attached directly to con-
necting terminals 9 and 10 of the 12-pin sensor connector
J8 in
the boiler control panel (see chapter 12.6).
1. Open the boiler control panel and remove the connector J8
from the switching panel PCB (see chapter 4.7.2).
2. Pull out the storage tank temperature sensor from the sensor
immersion sleeve at the storage tank.
3. Bend the pressing springs on the new sensor and push the
new sensor into the sensor immersion sleeve.
The insertion depth is marked on the ROTEX storage tank by
a coloured marking, depending on the storage tank type.
4. Connect the sensor cable to the connector on the connecting
terminals 9 and 10 of the 12-pin sensor connector J8 .
5. Plug the connector into the switching panel PCB and close
the boiler control panel.
Make sure there is sufficient tension relief on the sensor
cable.
