The “Tc” (7) and “Th” (8) sensors are fixed inside the appliance on the supply tube. To place them on the tank, remove
the cover and the frontal cover of the appliance, remove the two sensors and place them on the tank using the extension
cables supplied in the accessories bag (section 5.7.4).

Connect any integrative electrical resistance (17) with the interposition of a relay suitable for the electrical absorption of
the installed resistance (section 5.7.3).

Modify the operation of the internal pump, in this way the circulator will switch off 60 seconds after the compressor is
switched off: set Parameter “A1” to 0 . (section 7.5).
