The external temperature probe must be installed
on an external wall of the building avoiding:
---
the possibility of direct exposure to the sun’s
rays,
---
places subject to humidity or mould,
---
the proximity of fans, ventilation openings or
flue terminals.
Connection

tric wires which conform to the current regulations,
with flexible cord, each core having a cross sec-
tion area
not less than 0,50 mm

.
The connection wiring of the external tempera-
ture probe is part of a safety extra---low voltage
circuit therefore it has to be routed through a
duct separated from the mains voltage wirings.
The maximum allowable length of the wiring is
20 m.
For details concerning the connection of the
probe to the boiler refer to the instructions given
with the external temperature probe kit.
