OPERATION INSTRUCTIONS

ELECTRONIC CONTROL
Operation Modes

Turn on the convector, press the switch in position “I” (On) .
Time setting
The time setting is possible only in Off mode – the current day of the week, hour and minutes can be set.
To enter the time settings you need to keep simultaneously pressing the “ON/ OFF” and “Timer” buttons. The parameter which is being set blinks on the display. To select a parameter to set, you need to press briefly the “Timer” button. To exit the settings, you need to press briefly for a third time the “Timer” button (after you have set the minutes).
You begin the settings with selecting a day of the week from 1 to 7 depending on which in order the current day of the week is, and the setting is done by entering the respective number. The hour and the minutes are displayed simultaneously and the parameter which is being set is blinking. You can change the value of the parameter by using the and buttons.
If no button is pressed for 10 seconds, you will exit the settings.

Switching on “Heating” mode
When the panel convector is switched off, the digital display shows the room temperature and only the Temperature LED is lit. If you press the “On/Off” button once, you will enable “Heating” mode. A red LED is lit indicating this mode. The digital display shows the set temperature for about 2 seconds, and during this time the Temperature LED is not lit. If the room temperature is lower than the set temperature, the heater will be automatically switched on.
When the heater is on the red LED is permanently lit!

Temperature setting
By pressing either of the buttons and you will enter the “Change the set temperature” mode. The display starts flashing and it shows the temperature which has been set so far. By pressing the buttons you can change the temperature setting either up or down. If you don’t press any button for 5 seconds, the new setting will be stored and the appliance with automatically go into “Heating” mode. If you keep pressing any of the buttons   or  for more than 0.7 seconds, the value of the set temperature will start increasing or decreasing by 4 units per second. The temperature setting ranges from 10 to 30 degrees Celsius.

Note: The device shows the temperature around the location of the sensor and is not a means of accurately measuring the ambient temperature.
“Delayed start” of the panel convector
When the convector is in Off mode, by pressing the “Timer” button you can enter a specific time after which the appliance will automatically go in “Heating” mode. This mode is indicated by a blinking yellow LED and inactive red LED. The digital display will show the room temperature when the Temperature LED is lit, and it will show the remaining time in hours until the “Heating” mode will be activated and this will be indicated with a lit Timer LED. Upon activating this mode the yellow LED becomes lit, and the display starts flashing and showing the entered time in hours until the convector will be automatically switched on. Initially, the display will show 12 hours, and by using the or buttons you can adjust the desired time. If you keep pressing any of the buttons or for more than 0.7 seconds, the value of the set time will start increasing or decreasing by 4 units per second. If you don’t press any button for 5 seconds, or if you press the Timer button, the regulator will automatically go into “Delayed start” mode. If you enter time 00, this mode will not be activated. When the “Delayed start” mode is already active, if you press the “Timer” button again, you can correct the remaining time in both possible directions. After setting the time, the appliance goes into “Delayed start” mode with the display showing the temperature and the hours remaining until the appliance will switch to “Heating” mode. You can exit this mode by pressing the “On/Off” button. Then the convector will go into  “Heating” mode. The “Delayed start” mode can be set within a range from 01 to 96 hours.

Switching off “Heating” mode
You can exit “Heating” mode by pressing the “On/Off” button. Then the heater will be switched off, and if it has been on by then, the red LED will go out. The display will continue showing the room temperature.
“Anti-frost function”
If the room temperature falls below 5 degrees Celsius and the convector is off (the red LED is not lit, but the mechanical switch is in position “I” (On) ), the heater will be automatically switched on in order to prevent freezing.
Note: Entering a temperature correction for the temperature sensor does not apply to this function.

Enabling and disabling the anti-frost function:

• this function is enabled by default
• to disable this function, the convector must be in “Off” mode, when you press the and “On/Off” button for three seconds the display will show a blinking “ON”, and by pressing the button you will reach the “OFF” position, then you need to wait for 3 seconds and the function will automatically go in “OFF” mode.
• to enable this function again, the convector must be in “Off” mode, when you press the and “On/Off” button for three seconds the display will show a blinking “OFF”, and by pressing the button you will reach the “ON” position, then you need to wait for 3 seconds and the function will automatically go in “ON” mode.

“Temperature correction for the sensor” function
Due to the specifics of the temperature profile in some premises, there may be differences between the temperature shown on the display and the actually measured temperature in the various locations of the heating appliance in the room.

• See the temperature shown on the display of the appliance
• Measure the temperature at a place where the temperature is “comfortable” enough for you (usually at a height of 60 cm from the floor, in sitting position). If you find a difference within a range of ±4°С, you can set the necessary correction in the convector’s menu (It is important to note that this function can be set only after the temperature has become the same all around the room, and depending on the room type, the minimum required time is 7 hours) by entering the temperature difference resulting between the value on the display and the actually measured temperature.

Note: This function is used with the purpose of providing better temperature comfort and energy saving for the user of the electric convector in the room which it is in. A temperature difference greater than ±4 °C from the measured temperature in a specific location in the room indicates that the room where you use the convector in is not well insulated or the temperature is not the same all around the room.
Example: a convector in a room on a stone floor – the convector displays 18°С (the set temperature is 22°С), the actually measured temperature (feeling of reached comfort temperature) is 22°С at a height of 60 cm from the floor – > in this case the convector continues to overheat the room (this is a direct energy loss, but the convector cannot reach the set temperature because it measures the temperature at a low height close to the floor) and it will never switch off. In this case a temperature correction of +4°С needs to be applied to the sensor, thus the convector will display 22°С and it will start switching off, and eventually, it will maintain the set temperature of 22°С).
The normal status of the function is 0°C by default

• to change this value, the convector must be in “Off” mode, when you press the and “On/Off” buttons for three seconds the display will show a blinking “0oc”. You can press either the or  button to reach the „-4°С“ to „4°С“ range, then you need to wait for 3 seconds and the function will be automatically stored.
• to check what correction has been set, the convector must be in “Off” mode, when you press the and “On/Off” buttons for three seconds you will see the set temperature blinking on the display. By pressing the or buttons you can set a new value within a range from „-4°С“ to „4°С “.

Note: After activating the Return to Factory Settings function a new temperature correction has to be entered, the value by default is 0°С)

Adaptive start

• Adaptive start control is a function that predicts and initiates the optimal start of heating up in order to reach the set temperature in the desired time.
• this function is enabled by default
• to change the value, the convector must be in “Off” mode, when you press the „ “ and “Timer” buttons for three seconds the display will show a blinking “A_On”. You need to press the „ “ button to reach „AOFF“; then you need to wait for 3 seconds and the function will be automatically stored.
• To return to „ON“ status – the convector must be in “Off” mode; when you press the and “Timer” buttons for three seconds the display will show a blinking “AOFF”; you need to press the button to reach „A_On“, then you need to wait for 3 seconds and the function will be automatically stored.

This function can be set according to your needs. The appliance operates for 17 hours following the set “comfort” temperature until it reaches a stable status – this is the reference comfort temperature. Also, a temperature lower than the comfort one, with a difference from 4°C ± 1°С, has to be set for a period of minimum 7 hours. When the adaptive operation is enabled, leave the electronic thermoregulator of the appliance to operate for 4 cycles (4 х 24 hours) of comfort cycles (17 hours) and lower temperature (7 hours). Upon completion of the last period of low temperature, the comfort temperature should be reached within ± 30 minutes deviation from the set time, with a maximum difference of ± 1°C from the reference comfort temperature.

“Protection from children”
You can lock the buttons by continuously pressing the arrows and “Timer” buttons simultaneously, in order to prevent any changes to the settings.
Repeat the same action to unlock the buttons.
Note : If you press any of the buttons when the keypad is locked, the display will show „LOC_“

Settings in „Weekly programmer 24/7”
Note: Entering settings mode of “Weekly programmer” is possible only after the time and the day of the week have already been set in the appliance.
To enter and exit the settings mode you need to continuously press the “Timer” button.
There are three parameters to be set – day of the week, time and temperature; switching among the three parameters is done by shortly pressing the “Timer” button in the following sequence: day, time, temperature. To store the settings, press shortly the “Timer” button after you finish the temperature setting.
You can change the value of each parameter by using the and buttons.
Conditions for settings storing
a. After a point has been stored, it cannot be changed anymore until you exit the current setting.
b. Upon storing the first set point of a specific day in the current setting, all previously set points of the day are cleared.
c. Storing further points of a specific day is possible only for the hours remaining until the end of the day, after the last stored point.
d. When you have stored a point in the last hour of the day – 23.5h, you cannot store any more points for this day in the current setting, and the display will show “FUL” and the number of the day.
e. If nothing is stored in the current setting for a specific day, it will keep the existing stored points up to the current setting.
The purpose of the settings is to store the three parameters in the so-called “SET POINTS”, where the temperature set for each setpoint is implemented until the next one is reached.
Example: If you have stored the temperature to be 22°C at 7 h and you wish the temperature to remain the same until 19 h (you plan the temperature to increase to 23°C then), you do not need to store every single hour until 19 h, and you only need to store the temperature to be 23°C at 19 h. By default, the temperature will be 22°C during this period of time (7 – 19 h).

The procedure for storing each point is as follows:
Upon entering settings mode the display will show dAY1, with the numeral blinking to indicate that this is the parameter to be set (in this case it is the day of the week).

a. to select the desired day, use the and buttons
b. to go to the time set, shortly press the “Timer” button
c. use the and buttons to select the desired time (with a 0.5h interval) per point
d. to go to the temperature setting, shortly press the “Timer” button
e. to select the desired temperature, use the and buttons. The possible temperature range is from 10 to 30°С, and of status is possible as well.
f. To store the point, shortly press the “Timer” button; then you are automatically transferred to the setting of the next point (the display again shows dAYX) and you can proceed with paragraph а) for the next point.
g. When you have stored a point in the last hour of the day – 23.5h, you cannot store any more points for this day in the current setting, and the display will show “FUL_” and the number of the day.

Note: Points of a particular day may be stored only in ascending order of their times.
Note: Before implementing paragraph f) the user can go back to paragraph а) to correct the three parameters of a point by shortly pressing the ON/OFF button, without storing the settings in the memory.
Adding more points in a particular day may be done at random after you have stored points for other days, however, you need to observe the rule for ascending order of their times in a day.
To exit the settings mode, press continuously the “Timer” button and wait for 30 seconds.
Upon leaving the settings you can review the stored points by using the and buttons, provided that the appliance is in programming mode.
Note: When you turn on the appliance, it will start operating in the (heating or programming) mode which it has last operated.
Note: You can switch between the modes of operation (heating or programming) by shortly pressing the “Timer” button when the appliance is switched on.
“Return to factory settings” function
When the convector is in “Off” mode, press the and buttons simultaneously for six seconds; then the display will show „ __“ and rotating symbols. When it is “reset”, the display will show the measured value of the room temperature.
After using the reset function, you need to re-enter the settings of the following functions:

• time setting
• enter a value of the temperature correction (if needed)
• disable the “Anti-frost” function (if needed)
• disable the “Adaptive start” (if needed)
• weekly program – 24/7

If the electric convector is disconnected from the mains, this will not affect the set temperature and the mode of operation which has been active prior to its disconnection. If for example, the convector has been in “Heating” mode, after it has been disconnected and reconnected to the mains, it will continue operating in the same model with the same set temperature.
Note: The principle of operation of the electric convector with energy- independent memory is to store the settings for 90 minutes guaranteed, and up to 150 minutes not guaranteed.
When the room temperature is lower than the temperature set by the electronic thermoregulator, the convector will start operating and will continue operating until the room temperature reaches the set value. When the room temperature is higher than the temperature set by the electronic thermoregulator, the convector will automatically go into “Standby” mode.

Information presented on panel heater display
Indications when you are not in settings mode:
a. In Off mode – consecutively showing:

• time (hour and minutes)

• measured room temperature
  b. In Heating mode – it shows the measured room temperature
  c. In Programming mode – consecutively showing:

• Day of the week, low line and the measured temperature. 6_22

• Day of the week, low line and the temperature set in the program blinking (set for the current hour), which may be also the OFF symbol. 6_23
  d. Upon connecting the convector to power supply the display shows:

• Hyphens “—-“, if the appliance has been in Off mode before disconnecting it from the power supply.

• Hyphens “—-“, which in 2 seconds will be replaced by the value of the current temperature, if the appliance has been in On mode before disconnecting it from the power supply.
  e. Two numerals (01÷96) and a blinking yellow LED indicate the remaining time in hours until the delayed start, if the appliance has been in “Delayed start” mode before disconnecting it from the power supply.
  f. With the purpose of further energy saving, electronic thermoregulation reduces the brightness of illumination of all LEDs. Upon pressing any of the buttons the brightness increases for 8 seconds and it is then reduced again.
  g. If the display shows “t1” or “t2“, this means that the self-diagnostic system has found a problem with the temperature sensor. “t1” indicates a disconnected cable at the sensor, while “t2” indicates short circuit at the sensor. In this case the electric convector will be automatically switched off and it can be switched on again only after the problem has been fixed. The problem has to be handled by a qualified specialist.
  h. Upon switching on the power supply the display will show hyphens “—-“ for 2 seconds instead of the temperature of time.
  i. When the digital display shows the temperature the “Temperature” LED is lit, and when it shows the time, the “Timer” LED is lit.
