1 RECOMMENDATIONS REGARDING
SAFETY
Requirements concerning safety
are described in detail in
individual chapters of this
manual. Apart from them, the
following requirements should
in particular be observed.
Before starting assembly,
repairs or maintenance, as well
as during any connection
works, please make sure that
the mains power supply is
disconnected and that terminals
and electric wires are devoid of
voltage.
After the regulator is turned off
using the keyboard, dangerous
voltage still can occur on its
terminals.
The regulator cannot be used at
variance with its purpose.
Additional automatics which
protect the boiler, central
heating (CH) system, and
domestic hot water system
against results of malfunction of
the regulator, or of errors in its
software, should be applied.
Choose the value of the
programmed parameters
accordingly to the given type of
boiler and fuel, taking into
consideration all the operational
conditions of the system.
Incorrect selection of the
parameters can cause
malfunction of the boiler (e.g.
overheating of the boiler, the
flame going back to the fuel
feeder, etc.),
The regulator is intended for
boiler manufacturers. Before
applying the regulator, a boiler
manufacturer should check if
the regulator’s mating with the
given boiler type is proper, and
whether it can cause danger.
The regulator is not an
intrinsically safe device, which
means that in the case of
malfunction it can be the source
of a spark or high temperature,
which in the presence of
flammable dusts or liquids can
cause fire or explosion. Thus,
the regulator should be
separated from flammable
dusts and gases, e.g. by means
of an appropriate body.
The regulator must be installed
by a boiler manufacturer in
accordance with the applicable
safety standards.
The programmed parameters
should only be altered by a
person familiarized with this
manual.
The device should only be used
in heating systems in
accordance with the applicable
regulations.
The electric system in which the
regulator operates must be
protected by means of a fuse,
selected appropriately to the
applied loads.
The regulator cannot be used if
its casing is damaged.
In no circumstances can the
design of the regulator be
modified.
Electronic isolation of the
connected devices is applied in
this regulator.
The regulator consists of two
subassemblies. In the case of
replacing one subassembly,
make sure to maintain
compatibility with the other
one. More information on that
issue can be found in the
documentation intended for
fitters
Keep the regulator out of reach
of children.
