the electrical power of the controller, than in
cover of the controller switch the button into
manual control. Turn the cap of the valve
into closed position, then again switch the
button in the cover into AUTO. Connect the
electrical power to the controller - %
indicator of valve opening is calibrated.
Attention, in mixers No 2,3,4,5 calibration is
automatic after connecting electrical power.
In case of these mixers wait until indicator of
valve opening is calibrated in %. During
calibration the servomotor is closed through
valve opening time.
The calibration is
displayed in MENU – Information – mixer info
– “CAL”

CIRCULAR PUMP CONNECTION
Circular pump can be connected to boiler
controller only by extension module C.

TEMPERATURE LIMITER
CONNECTION
In order not to overheat the boiler due to the
controller breakdown it is obligatory to use
STB safety temperature limiter or any other
one suitable for given boiler. Limiter STB
should be connected to terminals 1-2. When
limiter is activated, blowing is stopped as
well as engine of fuel feeder.
Safety temperaturę limiter must
have nominal voltage at least
230V and should have valid
admission documents
In case of not installing the limiter terminals
1-2 are to be connected by a bridge. The
bridge must be made with insulated wire,
with diameter at least 0,75mm
2
.With
insulation which is thick enough to meet
safety standards of the boiler.

ROOM PANEL CONNECTION
It is possible to equip the controller with
room panel ecoSTER200, which has following
functions: room thermostat (controls up to 3
thermostats), controlling panel for the boiler,
alarm signal, fuel level indicator
The maximum cable length from
the terminal regulator to the room
panel should not exceed 30 m and
the cross section of of veins should
not be less than 0.5 mm2.
4 way connection
TOUCH ecoSTER connection must be in
accordance with the wiring diagram while
ecoSTER200 connect as shown below.
2 way connection
This connection requires the use of an
external power supply 12V DC with a current
of min. 200 mA. The panel points
ecoSTER200 / ecoSTER TOUCH: GND and
VCC / + 12V connected to the power supply.
The lines D +, D- connected according to the
wiring diagram and drawing for 4-wire
connection.
The power supply is not included with the
controller.
