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.
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
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 the temperature is 65ºC, then the 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.
Adjust 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.
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
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
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%.
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.
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
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.
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.
Exhaust temperature adjustment deactivation time.
The display shows the message (Fumes 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.
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.
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 .
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.
Locking the keyboard
If during normal operation (not in programming mode), the MENU button is pressed continuously the display shows the message (Lock) and the keyboard will be locked. This is used to prevent unwanted changes. If any key is pressed the display will show the message and no command will be executed. To unlock the keyboard press continuously the MENU button until the message (Unlock) is shown
