This document describes the Thermor EVIDENCE 2 ELEC 1500 convector heater, a Class II appliance designed for residential use and protected against splashed water (IP24). It is intended for installation in various rooms, including bathrooms (within Volume 2, provided controls are out of reach from a shower or bath). The device operates on a 220-240V 50Hz power supply.

Installation and Safety

The convector should be installed according to local regulations and trade practices, maintaining minimum clearance distances as shown in the diagrams. It should not be placed in draughts that could affect its control settings (e.g., under a fan or ventilation opening) or directly under a fixed mains power socket. For installations where the wall covering is foam, a spacer of the same thickness must be placed under the heater's support to ensure adequate air circulation behind the unit.

Vertical products should not be installed above an altitude of 1000 meters, as this can increase the air discharge temperature by approximately 10°C per 1000m of altitude. Horizontal installation of vertical products is prohibited.

The appliance is secured to a wall-mounted hook-on bracket. To install, first release the hook-on bracket by placing the radiant panel face down and using a flat-head screwdriver. The bracket is then fixed to the wall using drilling points A and B. It is crucial not to use the device with mobile feet or casters.

Electrical connection can be made via a 2-wire cable (Brown = Phase, Blue = Neutral) to a power socket or connection box (for mechanical thermostats), or a 3-wire cable (Brown = Phase, Blue = Neutral, Black = Pilot wire) to a connection box (for electronic thermostats with pilot wire). In humid areas, power sockets must be installed at least 25 cm above the floor. The installation must include an omnipole disconnection mechanism with a contact break distance of at least 3mm. Earthing of the convector is prohibited, and the black pilot wire must not be connected to earth. If the power cord is damaged, it must be replaced by a qualified electrician. If a pilot wire or piloted panel heater is protected by a 30mA differential, the pilot wire's power must also be protected by the same differential.

Control Unit Description

The control unit features a stop/0 switch, a temperature adjustment control knob, and a heating indicator light (V1).

Usage Features

Comfort Temperature Setting: This is the desired temperature when the room is occupied.
- Set the switch to "I" (on).
- For mechanical models, set the control knob between 4 and 5.
- For electronic models, set the control knob to 5; the V1 indicator will illuminate if the room temperature is below the set point.
- Allow several hours for the temperature to stabilize.
- If the setting is satisfactory (verify with a thermometer), mark the position for future use. If not, adjust and repeat the stabilization process.
Eco Temperature Setting (Electronic Models Only): This is the desired temperature for unoccupied periods, recommended for absences longer than 2 hours.
- Set the switch knob to the "Eco" symbol.
- Adjust the control knob between 3 and 4; the V1 indicator will illuminate if the ambient temperature is lower than the desired Eco temperature.
- Allow several hours for stabilization.
- Mark the satisfactory position or adjust as needed.
Frost-Free Mode: This mode maintains a temperature of approximately 7°C, suitable for prolonged absences (over 24 hours).
- Set the switch to "I" and the control knob to the "Frost-Free" symbol (mechanical models).
- Set the switch to the "Frost-Free" symbol (electronic models).
Heating Indicator (V1 - Electronic Models): This light indicates when the heating element is active. It may flash when the temperature has stabilized.
Locking Controls: The control knob and switch can be locked or limited to prevent unauthorized manipulation (e.g., by children).
- Unhook the panel heater from its wall mounting.
- Remove the slugs P from the back of the thermostat.
- Select position B to lock the control knob, or position L to limit its turning range. Position M blocks the switch for electronic models.
Pilot Wire Functionality: Products with a pilot wire can receive signals from a master unit for "Comfort," "Eco" (Comfort -3°C to -4°C), "Frost-Free" (approx. 7°C), and "Off" modes.
- Set the switch (1) to the programming mode (clock symbol).
- The product must be connected via the pilot wire to a programming control or a system with a pass program to utilize these modes. Multiple convectors can be controlled by a single programmer.
- Warning: The control unit will prioritize "Frost-Free" and "Off" signals regardless of the switch selection.

Recommendations for Use

Setting the heater to maximum will not make the room temperature rise faster.
When airing the room, switch off the panel heater by setting the switch to STOP/0.
For short absences (less than 2 hours), no adjustment is needed.
For absences of 2 to 24 hours, lower the control knob by two graduations.
For absences longer than 24 hours or during summer, set the control knob to "Frost-Free" (mechanical) or the switch to "Frost-Free" (electronic).
If multiple units are in one room, allow them to operate simultaneously for a more uniform temperature without increasing electricity consumption.

Maintenance

To maintain optimal performance, the upper and lower grilles should be cleaned with a vacuum cleaner or brush approximately twice a year. A professional check of the internal components is recommended every five years. Dirt accumulation on the grille due to polluted ambient air is not covered by warranty; in such cases, ensure proper room ventilation and clean air. The casing can be cleaned with a damp cloth; abrasive products should never be used.

Troubleshooting

If the unit does not heat:
- Check if the programmer is in COMFORT mode (electronic models).
- Ensure circuit breakers are on and the load shedder (if present) has not cut power.
- Check the room air temperature.
If the unit does not follow programming orders (pilot wire version):
- Verify correct use of the programming unit (refer to its manual) or that the Chronocarte is properly inserted and functioning (check batteries).
If the unit heats continuously:
- Ensure it is not in a draught and the temperature setting has not been changed.
- Electronic models with microprocessors can be affected by severe mains voltage disturbances. If problems occur (e.g., a blocked thermostat), cut power for about 5 minutes to reset the unit. If the issue persists, have your energy distributor check the power supply.

Warranty Conditions

The warranty is valid for 2 years from the date of original purchase, not exceeding 30 months from the date of manufacture. It covers the replacement of parts found to be defective in manufacturing. Labor, freight, and transport costs are not covered. The warranty does not cover damage due to neglect, shipping, accidents, incorrect installation, misuse, or failure to follow instructions. This document, along with the purchase invoice, must be presented for any warranty claims. The unit's type and serial number are located on the left side or behind the front grille.
