Using the boiler without a room con-
trol unit
When running in this mode, the boiler
maintains the selected heating water tem-
perature. No room control unit is connec-
ted, the terminals for its connection must
be interconnected with a jumper (standard
factory setting).
Setting procedure:
• turn the main switch to the ON position
(I)
• set the required heating water tempera-
ture on the control panel
Using the boiler with a room control
unit
The boiler maintains the
selected heating water
temperature. The room
control unit wiring termi-
nal jumper is removed
and the room control
unit is wired to the ter-
minals. The boiler is turned on and off to
maintained the set temperature in the room
in which the control unit is installed. This
room must not have thermostatic valves
installed on heating radiators.
When the room control unit turns the
boiler on, this status is indicated by a dot
after the number shown on the display.
Important
: You must set on the boiler
control panel a heating water temperature
(temperature of the water in the system)
which will be capable of covering thermal
losses of the building even in low outdoor
temperatures. We recommend to select
a temperature within the range of 60
- 80˚C.
Using the boiler with equithermal
control
The boiler changes the heating water
temperature as the outdoor temperature
changes.
Important:
An outdoor temperature sen-
sor must be connected to the boiler! The
outdoor sensor should be located on the
coldest wall of the building (facing north
or north-west), approximately 2.5 – 3 m
above ground level. The sensor must not
be exposed to any false heat waves from
open windows or ventilation shafts, or to
sunshine.
A rule applies when selecting a heating
curve that lower number curves are
suitable for buildings with good thermal
insulation and steeper thermal gradient,
and vice versa.
The thermal curve diagram is used as a
primary source of information. The system
should be fi ne-tuned by monitoring outdoor
and indoor temperatures for a few days.
For first setting of the system choose
curve E6.
When setting the system up, all radiator
valves must be fully opened, thermostatic
valves must be set to maximum temperatu-
re and doors and windows must be shut.
Setting the curve slope as well as the
parallel shift is done in small increments,
and after each step it is necessary to
wait roughly 2 hours and then assess the
change. It is better to do the setting when
the outdoor temperatures fl uctuate signifi -
cantly, and the fi nal setting should be done
when the outdoor temperature drops below
freezing point.
Setup procedure:
1. Select the “heating water temperature”
mode and make sure that the function
