5.7.2.- Installation of the DHW sensor (Tw)
on the storage tank
The DHW sensor is already connected to the terminal board
(Figure 5-10), it is sufficient to take it from the terminal board
compartment to the tank. Activate the DHW function following
section 7.5, Parameter “08”.
5.7.3.- Integrative electrical resistance
connection
For the integrative electrical resistance (detail “17” of Figures
from 4-3 to 4-6) it is necessary to introduce a support relay
at the output SH and N (Figure 5-15). This relay must have a
230V coil and at least 16A contacts.
