CONTROL BOX RMO... (A)
Warnings
To avoid accidents, material or envi-
ronmental damage, observe the fol-
lowing instructions!
WARNING
The control box RMO... is a safety
device! Avoid opening or modifying
it, or forcing its operation. Riello
S.p.A. cannot assume any responsi-
bility for damage resulting from
unauthorised interventions!
• All interventions (assembly and installation
operations, assistance, etc.) must be carried
out by qualified personnel.
• Before modifying the wiring in the control box
connection area, fully disconnect the system
from the power supply (omnipolar separa-
tion). Check the system is not powered and
cannot be accidentally reconnected. Failure
to do this will lead to the risk of electrocution.
• Protection against electrocution from the con-
trol box and all connected electric compo-
nents is obtained with the correct assembly.
• Before any intervention (assembly and instal-
lation operations, assistance, etc.), ensure
the wiring is in order and that the parameters
are correctly set, then make the safety
checks.
• Falls and collisions can negatively affect the
safety functions.
In this case, the control box must not be oper-
ated, even if it displays no evident damage.
• Press the reset button of the burner lockout
command or the reset button (by applying a
force of not more than 10 N), without the aid
of tools or sharp objects.
For the safety and reliability of the control box,
comply with the following instructions:
• avoid conditions that can favour the develop-
ment of condensate and humidity. Otherwise,
before switching on again, make sure that the
entire control box is perfectly dry!
• Static charges must be avoided since they
can damage the control box's electronic com-
ponents when touched.
Mechanical structure
The control box is made of plastic to resist
knocks, heat and flame propagation.
The control box contains the following compo-
nents:
• a microprocessor that controls the program
sequence, and a relay for controlling the load
• an electronic flame signal amplifier
• a built-in reset button with 3 signalling colours
(LED) for status and error messages.
