BASIC SETTINGS
When the unit is powered for the first time all the
indicators and the LED display are lit. After that a
factory number is shown and the unit goes to a
standby state. The display shows .
Here we can adjust the required setting
depending on the type of wood burner. To enter
the settings adjustment menu we must press
continuously the button for a few seconds until
the display shows the message .
Immediately after pressing one of the keys (+) and
(-), the display will scroll all the programming
parameters of the device. When the desired
parameter is displayed by pressing the MENU
button the initial value can be changed to the
desired value using the (+) and (-) buttons.
Whichever of the buttons (+) or (-) is pressed
constantly, changes the value quickly, not
requiring repeating presses.
If the MENU button is pressed again, the value is
stored in the device memory and the display
shows the name of the parameter that you just set.
Below are the programming parameters as would
occur if the button (+) is repeatedly after the
message is shown:
1. Circulator start temperature setting
The display shows the message (Circulator
Start Temperature). Pressing the MENU button
will show the factory default setting which is 45ºC.
This value can be adjusted from 35–60ºC and sets
the water temperature above which the circulator
starts to operate. If the water temperature is lower
then the selected value then the circulator does
not operate.
2. Safety level temperature adjustment.
The display shows the message (Over Heat
Limit). Pressing the MENU button will show the
factory default setting which is 85ºC. This value
can be set between 86°C and 95ºC and
determines the overheating level of the water.
If the water temperature exceeds this level then
the message (High Temperature) is shown,
and the buzzer is activated with an intermitted
sound.

3. Adjusting the lower temperature level for
controlling the speed of the fan.
The display shows the message (Low Fan
Temperature), by pressing the MENU button the
factory default setting will appear which is 55ºC.
With this setting we can adjust the temperature of
the water from which the fan will gradually starts to
decrease its speed. The value can be set from
50ºC to (4) decreased by 1. For example if
th e t e mp er at ur e i s 6 5º C,t h en t h e
temperature can be adjusted from 50-64ºC.
The decrease in the fan speed is done gradually
until the (4) temperature is achieved and
finally the fan will stop.
4. Adjusting the higher temperature level for
controlling the speed of the fan.
The display shows (High Fan Temperature),
by pressing the MENU button, the factory default
setting will appear which is 72ºC. With this
arrangement we can choose the water
temperature above which the fan will stop
operating, since the rotation speed starts to
decrease when it starts to become greater than
the value (3) and regulated by the
temperature increased by 1 up to 85ºC. The
automatic fan speed adjustment is done between
the lower temperature and the
temperature . If these two temperatures
and are adjusted as to have a
difference of only 1°C then the fan operates in
ON/OFF mode.
5. Flame sustentation setting
The display shows the message (FiL
Temperature) by pressing the MENU button, the
factory default setting will appear which is 35ºC.
With this setting we adjust the water temperature
below which (if there is not a command from the
room thermostat) the fan will turn in maintenance
state. In this state the screen shows , the
buzzer sounds for 3 minutes, the fan speed is
lowered to the value increased by 15 units
and follows an activation/diactivation cycle
depending on the values and in order to
sustain the flame for as long as possible. If the
water temperature becomes greater than this
value or there is a command from the room
thermostat, then the unit enters normal operation.
This value can be adjusted from 10 to 50 °C.
6. Adjusting the maximum fan speed.
The screen shows the message (Speed
High) by pressing the MENU button the factory
default setting will appear is 100%. With this
setting we select the maximum speed of the fan in
order to adjust to the needs of different types of
wood burners. The adjustment value can be set
from +1 to 100%. During the adjustment
process the fan changes speed accordingly.
7. Adjusting the minimum fan speed
The display shows (Speed Low). By pressing
the MENU button, the factory default setting will
appear which is 30%. With this adjustment we
determine the minimum speed that the fan can
turn.
To determine this speed select 10% and wait until
the fan stops. Gradually increase the value until
the fan starts to rotate.
This value is different for every type of fan and in
conjunction with the define it’s operation
range. The value can be adjusted from 10% tο
50%.
8. Adjusting the activation time of the fan
during the flame sustentation mode.
The display shows the message (Time on).
By pressing the MENU button, the factory default
setting will appear which is 1 minute. With this
setting we can adjust the activation time of the fan
when the unit is in flame sustentation mode. If the
value ``0΄΄, is selected the fan will remain
permanently deactivated during the flame
sustentation mode. The value can be adjusted
between 0 and 250 minutes.
9. Adjusting the deactivation time of the fan
during the flame sustentation mode.
The display shows the message (Time off).
By pressing the MENU button, the factory default
setting will appear which is 10 minutes. With this
setting we select the deactivation time of the fan
when the unit is in flame sustentation mode. The
setting can have values from 1 to 250 minutes.
10. Fumes Sensor Select.
The display shows the message (Fumes
Sensor Select). By pressing the MENU button, the
factory default setting will appear which is .
The value can be set between and , and
specifies whether the smoke sensor will be active
or not. If has the value the parameters 11,
12, 13 have no meaning and therefore can not be
changed by the controller.
11. Fumes Temperature Adjustment.
The display shows the message (Fumes
Εffect Temperature). Pressing the MENU button
will show the factory default setting which is
150ºC. This value can be set from 100 °C to 400
°C and defines the temperature that the exhaust
should have to achieve the highest possible
performance of the wood burner. The fan’s speed
fluctuates to stabilize the temperature. The
process of regulating the exhaust temperature is
performed only if the parameter value or the
value is outside of their limiting action.
12. Exhaus t tempe rature adjustment
deactivation time.
The display shows the message (Fumes
940844002_09_004

effect dead time). Pressing the MENU button will
show the factory default setting which is 60'. The
value can be set from 0-250' and sets the start
time of the device, in which the selection will
not affect the fan’s speed. If the circulator
operates this time is not considerable. If time is
finished and the circulator is off , the control thru
the exhaust sensor is not activated , so the value
of the time must be adjusted so that the water
temperature on the completion of this time must
be greater than the activation of the circulator’s
temperature. If the time value is set to 0, the time is
canceled permanently and the value ,
(paragraph 13) determines when the exhaust
temperature adjustment (paragraph 11) takes
effect.
13. Switch-off temperature setting of exhaust
temperature influence.
The display shows the message (Heating
water Effect temperature). Pressing the MENU
button will show the factory default setting which is
40ºC. This value can be set from 10°C - 90°C and
defines the water temperature above which the
exhaust temperature control (paragraph 11) may
take effect. This parameter is active only if the
value (paragraph 12) has the value 0.
14. Buzzer mode setting in maintenance flame
sustentation.
The display shows the message (Buzzer
FIL). Pressing the MENU button will show the
factory default setting which is 3. The value can be
set from 1 to 4 and specifies the buzzer’s
operation when the device is in maintenance
flame sustentation (when the display shows the
message ). With value 1 the buzzer sounds
continuous but intermittently. With value 2 will
sound for 3 minutes and then will be turned off.
With value 3 will sound for 3 minutes and then will
beep every 10 seconds. Finally, with value 4
buzzer shuts off completely for the situation .
15. Factory settings restore.
The display shows the message (Factory
settings). By pressing and holding the MENU, the
device will erase all parameters by replacing their
values with the default values. Immediately after
executing the process of connecting to the mains,
as mentioned in chapter BASIC SETTINGS.
The next press of the button (+) the options cycle
is completed and the display shows the first
choice starting again the same cycle. To
complete the setup procedure and the integration
of programming, the button must be pressed
again. You will hear a beep from the thermostat’s
buzzer and the display with show , indicating
that the device is in standby mode. If , after this,
the button is pressed again the device enters
normal operation mode.
FAN’S MANUAL OPERATION
If, in normal operation, one of the keys (+) or (-) is
pressed, the display will show the current value of
the fan’s speed which the user can set from the
value increased by 1. The manual option is
stored in the place of the value .
This feature is not executed when the water
temperature lies between and (range of
automatic speed control). Simultaneously, the
speed control of the smoke sensor is canceled
and can be restored only if the water temperature
drops below the temperature or the device is
deactivated and reactivated again.
FROST PROTECTION
If the water temperature drops below 5°C then,
regardless of the operating status (active or
standby), the device activates the circulator and
maintains it, for as long as the temperature
remains below 5°C.
OVERHEAT PROTECTION
To reduce the chance of water overheating, the
circulator does not stop even after you turn off the
device by pressing the ON-OFF button . It is
deactivated only if the water temperature drops
below the starting circulator’s temperature .
SENSOR MALFUNCTION
If, for some reason, the water temperature sensor
is short-circuited, the display shows the message
(Error Low) the buzzer is activated and the
fan is deactivated. This situation remains until the
malfunction of the sensor is restored. The device
also has the same behavior when the sensor’s
cable is interrupted, so the screen will display the
message (Error High) when the water sensor
is interrupted and when the smoke sensor is
interrupted. If the smoke sensor is disabled, its
status will be ignored. If the device turns into
standby mode by pressing the button, the
buzzer will turn off.
SELECTION OF THE TEMPERATURE
INDICATION
In idle state the device displays on the screen, the
water temperature. If the MENU button is pressed
the display will show the smoke temperature, and
the dot on the right will be active (i.e ). If the
MENU button is pressed again the display will
show the water temperature.
