WARNING
In case of applications that use the connections of
the heat request thermostat TL (T1, T2), it is nec-
essary to insert a decoupling relay (230 Vac) with
the clean contact connected to inputs T1 and T2
of this wiring diagram.
WARNING
 Do not invert the neutral with the phase in the
electrical supply line.
 Check that the electrical supply of the burner
corresponds to that shown on the identifica-
tion label and in this manual.
 The section of the conductors must be at
least 1 mm
2
. (Unless requested otherwise by
local standards and legislation).
 Connect the 2nd stage thermostat (TR)
(Fig. 8 on page 7) to the terminals T6 - T8
removing the jumper.
WARNING
Check the burner stops by opening the thermo-
stats and check it locks out by opening the con-
nector (CN1)(Fig. 7 - Fig. 8 on page 7) inserted in
the probe's red wire, located on the outside of the
control box.
CAUTION
If the cover is still on, remove it and proceed with
the electric wiring following the wiring diagrams.
Use flexible cables in compliance with EN 60 335-
1 standards.
