Information on extension kit, part no. 7301 062
For DHW heating, the following must be ordered separately:
For DHW heating, the temperature sensor with part no. 7438 702 is
used as a cylinder temperature sensor (sensor well to be ordered sep-
arately if required).
The contact temperature sensor, which is part of the extension kit
delivery, is used as a return temperature sensor.
