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 presses for 10 seconds, you will exit the settings.
Switching on“Heating”mode
When the panel convector is switched o, the digital display shows the room
temperature and only the Temperature LED is lit. If you press the“On/O”
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 ashing 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 pressed 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 O mode, by pressing the“Timer”button you
can enter a specic 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
“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 ashing 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 pressed
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/O” 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 o“Heating”mode
You can exit “Heating”mode by pressing the “On/O” button. Then the heater
will be switched o, 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 o
(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 from freezing.
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“O”mode, when
you press the and“On/O”button for three seconds the display will
show a blinking “ON”, and by pressing the button you will reach the
EN
4Operation and Storage Manual of Panel Heater
“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“O”mode, when
you press the and“On/O”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 specics of the temperature prole in some premises there may be
dierence from 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 oor, in sitting
positon). If you nd a dierence 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 dierence 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 dierence greater than ±4 °C
from the measured temperature in a specic 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 oor – 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 oor - > 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 oor) and it will never switch o. 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 o, 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“O”mode, when you press
the and “On/O” 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 “O”
mode, when you press the and “On/O”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 which 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 “O” 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“O”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 dierence 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 lowered 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 dierence 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”
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 nish 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 any more until you exit the
current setting.
b. Upon storing the rst set point of a specic day in the current setting, all
previously set points of the day are cleared.
c. Storing further points of a specic 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 specic 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 set point 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 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 time setting, 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 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 OFF 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.
ATTENTION: 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
EN
Operation and Storage Manual of Panel Heater 5English
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 “O” 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 programme - 24/7
If the electric convector is disconnected from the mains, this will not aect
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 mode with the same set temperature.
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 O 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 programme
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 O 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, the electronic thermoregulator
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 o and it can be switched
on again only after the problem has been xed. The problem has to be handled
by a qualied specialist.
h. Upon switching on the power supply the display will show hyphens “----“ for 2
seconds instead of 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.
