been observed.
INSTALLATION
During the first use and for a few minutes, could occur smells and noise due to
the dilatation of some internal parts. This is normal, so you must provide
adequate ventilation. The smells are momentary and quickly will dissipate.
For greater efficiency, make sure to calculate the power or the number of
elements of the apparatus according to the surface of the room. We
recommend contacting your dealer performing this calculation.
Fix the radiator to a firm wall and make sure it is well-levelled, in a room with
no furniture and no objects avoiding around.
Avoid installing the appliance in corners.
We advise against installing the appliance under the windows, because it is
favoring the heat loss.
The radiator must be away, at a minimum distance of 15 cm from any
combustible material, curtains, furniture, chairs, etc.(Fig. 1).

SMARTBOX INSTALLATION
To control the radiators through Web app or Smartphone apps, a smart box that
connects the radiators to the Internet is required, using the house’s router.
The smart box communicates with the radiators by radio and with the router through
an Ethernet cable (supplied).
The process to follow is shown here:
1. Connect the smart box to the router.
2. Connect the smart box to power supply.
3. Check the status of the LED pilot lights.
Normal: orange light on, alternating with green light every 5 secs.
If this is not the case, consult point7. Possible problems and solutions.
4. Register with HJM through the app that can be found on Google play or Apple
store.

5. Access the app through your account and configure the house’s data,
automatically detect the smartbox and then follow the instructions on the
screen.
PAIRING RADIATORS WITH THE SMARTBOX
The radiators have to be paired with the smart box in order to be controllable
through the apps.The link indicator will appear on the screen when it is paired.
Once you have a user’s account and registered your smart box, you can use the
app. Click “install” (instalar) and follow the wizard:

Made in Spain
9/24
To pair the radiator with the smart box, it must be in discoverable mode.
Press the button at the rear of the smart box for 3 secs. to activate discoverable
mode.
The orange light flashing every second indicates that discoverable mode is
activated.
With discoverable mode activated in the smart box, press the key for 3 secs.
until the “Link” symbol appears on the radiator screen.
The radiator will now be paired with the smart box. Now you can control the radiator
programming and the temperatures through the HJM app.
You can un pair the radiator from the smart box by resetting the radiator.
PAIRING THE CONSUMPTION METER WITH THE SMARTBOX
The radiator installation can come with an electricity consumption meter that can be
used to both know the electricity consumption in the house and to coordinate
radiator consumption in order not to surpass the power limit when turning on ovens,
irons, washing machines etc..
The meter is only valid for single-phase installations.

This device is inserted into the house’s fuse box.
The house’s electricity must be switched off before installing it.
Connect the device to a 230V power supply. Connect the meter clip and clasp it to
the house’s main cable.
To pair the meter with the smartbox, once discoverable mode has been
activated(as shown on page 9), press the button inside the device with a paperclip
or pointed object:
Through the app, you will be able to see electricity consumption in real time and be
able to check consumption by day, month or year:

5.5.- C5: Open window detection
The radiator has the option to activate open window detection. By activating this
parameter, the radiator automatically disconnects when it detects a drop in
temperature in the room caused by the opening of a window or similar. This means
that when the temperature in the room drops 2,4ºC in 4 minutes, the radiator will
disconnect for 30 minutes. After this time, the radiator will connect again in the
same mode that it was in before disconnecting.
When it is activated, the following icon will appear on the screen: .

7. POSSIBLE PROBLEMS AND SOLUTIONS
1) The smart box does not connect. Check that it is plugged in and correctly
connected to the Internet through the Ethernet without a proxy and with ports
123UDP, 5000TCP open.
The LED lights on the smart box indicate the following:
Green off and intermittent orange every second: smart box in discoverable
mode.
Orange on and intermittent, very fast green: the router does not assign a
valid IP to the smart box.
Orange on and flashing green every 5 secs.: smart box with IP but does not
communicate with server.

HJM_RFC_WIFI_ENG_Rev.0_13-11-2018
Made in Spain
18/24
Orange on and alternates with green every 5 secs.:smart box with IP and
communication with server.
2) Equipment does not communicate with the smart box:
Make sure that the equipment is previously paired with your smart box. The Link
icon appears static on the screen.
If the distance, in interiors, from the router to a radiator is greater than 30m and
there are 2-3 walls between them, first pair the nearest radiators as each device
can function as a relay and, the more devices there are, the greater the scope of
the network.
If the "Link" icon flashes this is because it is paired with the smart box but cannot
communicate with it. Check that the smart box is correctly connected or if some
device that was functioning as a relay has been eliminated. Try placing nearer the
devices.
3) If the problems continue, try resetting or restarting the devices and try it again.
4) Error messages:
-OC: Temperature sensor not present
-SC: Temperature sensor short-circuit
-Err1: Operating element (Relay or Triac) short-circuit
-Err2: Overload (more power than allowed)
-Err3: Low charge (low power, check connection with resistance)
-Err4: Overheating (>90ºC in the electronic zone)

9. RESET THE RADIATOR
To reset the radiator, press the and keys together for 10 secs. The "rES"
message will appear on the screen.
Then press the key to confirm the Reset.
THERMAL SAFETY
In the case of overheating, a safety device automatically cuts the radiators
operation. After cooling the radiator will automatically reset.
MAINTENANCE
Your radiator requires no regular maintenance, however, to ensure its good
operation:
Always disconnect the device from the mains before performing any cleaning or
maintenance operation.
Let it cool down before cleaning.
To avoid any risk of electrical shock, clean the unit with a soft, damp cloth to wipe
the outside of the radiator and remove dust and dirt cloth.
Do not use detergent, solvent, abrasive products or any other chemical product to
clean the radiator.
NEVER immerse the device in water or any other liquids.
You can use a vacuum or flexible brush to clean the air grilles. This maintenance
must be carried out regularly to ensure optimum performance. Ensure the radiator
is totally dry before turning it back on.
