To make the electrical connections of the room thermostat (TA)
or of the remote control (optional OCDS006) or of an external
request, proceed as described below.

by means of two non-polarized conductors through
which it receives the power supply necessary for its op-
eration and carries out communication between the two
devices. Use a cable with a cross-section between 0,5
and 1,5 mm², with a maximum length of 50 metres.
