Connection to pumps
Condexa Pro2 EVO regulation system includes the simultaneous
management of up to three circulators.

The pumps and others external components have to be in-
stalled using an adequate relay/commutator, as shown in
“Figure 10”. Use a H05-VV-F type cable with minimum ex-
ternal diameter of 6 mm and adequate conductor section
to connect the terminal board to the relay (to be housed in
a special external board), being careful to fix the latter to its
cable guide.
For example, by connecting the low temperature circulator to
a timer and/or external room thermostat the electrical instal-
lation will be the one shown in “Figure 11”. . By this system is
possible to power on circulators (external devices) directly from
the network with no electrical load passing through the fuse of
the board.
Moreover, in case of emergency mode, the manual device 0, 1,
AUTO controls the operation of the pump regardless of what the
board. For these reasons it must explicitly provide for the use.
Use a bi-polar cable of the power cable sort (unless otherwise
recommended by the component’s manufacturer..
