Connection of OCDS011 DHW buffer tank
probe
The SB buffer tank probe (optional OSND011) must be connect-
ed to terminals 34-35 of the electronic board (master board for
Caldaria 100.2), removing the electric resistance fitted as stand-
ard (Figure 4.8 p. 33).
The DHW buffer tank probe must be used as an alternative to the
DHW buffer tank thermostat (Paragraph 4.5.3 p. 33).
The supplied cable length is 3 meters.
If a longer length is required, a 2x0,75 mm² shielded cable with a
maximum length of 50 metres must be used.
For further information, refer to the documentation sup-
plied with the DHW buffer tank probe OSND011.

The DHW buffer tank thermostat must be used as an alternative
to the DHW buffer tank probe (Paragraph 4.5.2 p. 33).
The cable may not be longer than 50 metres, with a minimum
cable cross-section of 0,5 mm 2 .
