2.3 How to install the panel heater?

2.3.1 Preparation

a. Release the appliance's hook-on bracket (Figure 5)

- We recommend that you place the panel heater flat, face down. Take a flat head screwdriver and lift the tab taking care not deform. While holding the tab lifted, push the locking bracket to the bottom of the unit to release the upper hooks. Rotate the attachment tab around the lower hooks and remove the attachment tab.

b. Fix the hook-on bracket (Figure 6)

- Place the bracket on the ground and against the wall and mark the drilling points A. These give the position of the bottom fasteners. Replace the brackets in alignment with the drilling point A to locate drilling points B. These give the position of the upper fasteners. In case of special support, use proper anchors. Position and screw the wall brackets.

2.3.2 Electrical connexion

- The appliance should have a 230 V / 50Hz power supply. The panel heater must be connected to the mains by a 2-wire cable with plug or 3-wire cable (Brown= Phase, Blue = Neutral, Black = Pilot wire) by means of a connexion box. In humid

areas such as bathrooms and kitchens the power socket must be installed at least 25 cm above the floor. The installation should be fitted with a double pole break device with a break of at least 3 mm.

- Connection to earth is prohibited / Do not connect the pilot wire (black) to earth. If a master appliance or a slave appliance is protected by a 30mA differential (e.g. for bathroom) it is necessary to protect the power supply of the pilot wire on that differential, too.

3. Utilisation

3.1 How to fix the comfort mode? (Figure 8)

- The Comfort mode allows setting the desired temperature using the control knob.

- Put the switch H on ⚙, and then set the control knob I on the desired position, the heating indicator G lights if the ambient temperature is lower than desired one. Wait until the temperature stabilizes.

3.1.1 How to fix the Eco mode?

- ECO mode allows lowering the temperature of Comfort mode from 3 to

4°C during unoccupied periods of the room. It is recommended that this mode should be used if the room is unoccupied for more than 2 hours. Put the switch H on ECO and then set the control knob I to the desired position, the heating indicator G lights if the ambient temperature is lower than desired ECO temperature. Wait until the temperature stabilizes.

3.1.2 How to fix the Frost Free mode?

- It is the position of the switch that keeps the temperature at approximately 7^ C in the room during prolonged absence from the house (usually more than 24 hours). Put the switch H on ✉.

3.1.3 How to program your device in Comfort, ECO or Frost Free mode?

- Devices equipped with an electronic thermostat are able to receive orders. There are two solutions:

• By pilot wire (black wire) for devices without plug thanks to the system Chronopass or a wall pilot wire box
• By carrier current with an interface on each device in addition to a Chronopass system or a wall carrier current box.

3.1.4 How to lock the commands (Figure 9)?

It is possible to lock or limit the use of the control knob I and to lock the switch H to prevent manipulation. Lift the unit from the wall bracket. On the back of the thermostat, remove the pins J from their support:

• The K position allows locking the control knob.
• The L position allows limiting the utilisation of the control knob.
• The M position allows locking the H switch on the desired mode.

4. Recommendations for use

• There is no point in setting maximum heating; the room temperature will not rise any quicker. If you leave for several hours, remember to reduce the temperature.
• If you have several units in a room, let them operate simultaneously. This will give you a more uniform temperature without increasing electricity consumption. This also applies for an unoccupied room; it is more interesting to let the device operate on a lower setting than turn it off completely.

5. Maintenance

• To maintain performances of your unit, you should clean the upper and lower grids of the unit about twice a year using a vacuum cleaner or a brush.
• Have a professional check the inside of the unit every five years. Dirt may collect on the grids of the unit if the atmosphere is polluted. This phenomenon is due to the poor quality of the ambient air. In this case, it is recommended to check that the room is well ventilated (ventilation, air inlet, etc.), and that the air is clean. The unit will not be replaced under the guarantee because of this type of dirt. The unit casing should be cleaned with a damp cloth, never use abrasive products.

6. Trouble-Shooting

• The device does not heat: Make sure that the installation circuit breakers are switched on, or that the load shedder (if you have one) has not switched off the unit power supply. Check the air temperature in the room. For the device equipped, check that the programmer is in Comfort mode.
• The unit is permanently heating: Make sure that it is not in a draft and that the temperature setting has not been changed.
• The unit does not carry out programming orders (Device equipped): Make sure that the programming unit is being correctly used (refer to its user's manual) or that the Chronocarte is properly inserted in its housing and that it is operating normally (batteries). The device with electronic control is equipped with a microprocessor that can be distributed by some severe mains voltage disturbances (outside EC standards defining the disturbance protection level). If there are any problems (thermostat blocked, etc.) switch off the unit power supply (fuse, circuit breaker, etc.) for about 5 minutes to allow the unit to start again. If this phenomenon occurs frequently, control the power supply by your energy supplier.
• The device is very hot on the surface: It is normal that the device when working, the maximum surface temperature is limited in accordance with standards. However, if you believe that your radiator is still too hot, make sure the power is adapted to the surface of your room (we recommend 100W / m2) and the unit is not placed in a stream of air that would disrupt its regulation.
