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 controller is turned off,
dangerous voltage still can occur on
its terminals.
• The controller 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 controller, 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 controller is intended for boiler
manufacturers. Before applying the
controller, a boiler manufacturer
should check if the controller’s mating
with the given boiler type is proper,
and whether it can cause danger.
• The controller 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 controller should
be separated from flammable dusts
and gases, e.g. by means of an
appropriate body.
• The controller 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
controller operates must be protected
by means of a fuse, selected
appropriately to the applied loads.
• The controller cannot be used if its
casing is damaged.
• In no circumstances can the design of
the controller be modified.
• Keep the controller out of reach of
children.
