Installation Guide

The installation of this heater must be executed by a qualified person, where required by law.

Mounting Steps

Recessed Wall Mounting

Provide a minimum opening of 2 5/8 in. (67 mm) deep. The hole must be cut precisely using the provided template. The bottom of the unit must be at least 6 in. (152 mm) from the floor and 2 in. (51 mm) from adjacent walls. An installation height of 12 in. (305 mm) from the bottom of the unit is recommended for better temperature regulation.

Diagram Description: Diagram illustrating recessed wall mounting: shows a wall opening with specified dimensions for depth and overall size, along with minimum clearance requirements from the floor (6 inches / 152 mm) and adjacent walls (2 inches / 51 mm). A template is provided for accurate wall cutout.

Surface Wall Mounting

The bottom of the unit must be at least 6 in. (152 mm) from the floor and 2 in. (51 mm) from adjacent walls. An installation height of 12 in. (305 mm) from the bottom of the unit is recommended for better temperature regulation. Locate the supply wire position and make a 1 in. (25 mm) diameter hole. Firmly install the 3 screws supplied to the wall. Do not overtighten, as you will need to slide the heater at step 6.b).

Installation Procedure

1. Use the template provided with the heater.
2. Remove the front cover by unscrewing the screw in the air outlet (at the bottom) and sliding the front cover upwards.
3. Disconnect the thermostat from the casing by pulling the white plastic connector (for models with a built-in thermostat) and place the front cover on a clean surface.
4. Remove the connection box cover. Remove the appropriate knock-out from the box for the electrical supply.
5. Wire the heater according to national and local codes and the wiring diagram.
6. Installation:
   • Recessed wall mounting: Install the casing in the wall opening using the holes located on the edge of each side of the recess box.
   • Surface wall mounting: Align the oversized part of the holes with the screws already on the wall, then slide the heater downward. Ensure the 3 screws are well supported at the top of the keyhole (small part). Once the heater is in place, finish tightening the 3 screws.
7. Reconnect the thermostat to the casing by clipping both parts of the white plastic connector together. Replace the flat cable in the wire clip.
8. Put the connection box cover back.
9. Reinstall the front cover by inserting the 2 tabs located at the top of the front cover into the 2 slots located at the top of the casing, then tighten the screw located in the air outlet. Ensure the front cover is properly seated and secure to the casing.
10. Test the heater. (Models with a built-in thermostat start with a calibration sequence). Adjust the heater thermostat to maximum setting. A slight heating smell may emerge from the openings; this is normal and will stop after a few minutes. Adjust the thermostat to minimum setting.

Operating Modes

To change the operating mode, simultaneously press the two adjustment buttons [adjust-up] and [adjust-down] for 1 second. The thermostat offers three primary operating modes, indicated by an icon on the screen.

• Comfort mode (White): Preferred mode when heating is necessary for comfort. Adjustment range: 10°C to 30°C (50°F to 86°F).
• Economy mode (Green): Mode for times requiring less heating. The set temperature is lowered by -0.5°C to -5°C. Useful for sleeping or when away from home to save energy.
• Freeze Protect mode (Blue): Mode for when minimal heating is necessary, such as during absences. Sets the temperature between 5°C to 10°C (41°F to 50°F).
• Boost mode (Purple): Suggested for rapid heating. Activate by pressing the Hourglass button [hourglass] for 1 second. The display will flash showing the boost time. The boost time can be increased by 5-minute increments by pressing the Hourglass button again. The boost mode stops automatically after the set time or by pressing the Hourglass button for 3 seconds. The boost time can also be adjusted by 1 minute using the adjustment buttons.

Configuration Menu

To configure thermostat parameters, press the [power-on] and [standby] buttons simultaneously for 3 seconds until the display flashes yellow. Use the adjustment buttons [adjust-up] / [adjust-down] to select parameters and the [power-on]/[standby] buttons to advance or exit.

Configuration Options:

• Temperature Display: Set to °C or °F.
• Economy Mode: Set temperature offset between -0.5°C to -5°C.
• Freeze Protect Mode: Set temperature between 5°C to 10°C (41°F to 50°F).
• Ambient Temperature Offset: Adjust to match the displayed temperature with the actual room temperature.
• Locking: Prevents unwanted adjustments to temperature or modes.
• Light: Set to ON (always on) or AUTO (off after 5 seconds of inactivity).
• Brightness: Adjust screen brightness on a scale of 1 to 5.

To exit the configuration menu, press the [power-on] and [standby] buttons simultaneously for 3 seconds or wait 5 seconds.

Display Indicators

The thermostat displays the measured room temperature by default.

Diagram Description: The thermostat display includes heating intensity indicators, visualized as a series of bars representing 20%, 40%, 60%, 80%, and 100% of maximum heating output.

Diagram Description: Fan intensity is indicated by a similar bar graph display, showing levels such as 100% and 50%.

To display the set temperature, press one of the adjustment buttons for 1 second. The set temperature appears for 5 seconds. To change the set temperature, press one of the adjustment buttons for 1 second, then press the adjustment button repeatedly until the desired temperature is displayed.

Standby and Power On

Standby deactivates all heater functions. To put the heater on standby, press the [power-on]/[standby] button for 4 seconds. The display will show a countdown from 4 to 1, then "<< OFF >>". To power on the heater, press the [power-on]/[standby] button for 3 seconds. The unit will operate in the last mode stored in memory.

Calibration Sequence / Power Outage

Upon connection or after a power outage, the heater starts a calibration sequence (display shows "CAL", buttons flash cyan, fan runs at full power for 60 seconds). All buttons are deactivated during calibration. Once calibration is complete, the room temperature is shown, and the last operating mode is activated. If calibration fails, error code E9 appears. Press the [power-on]/[standby] button for 3 seconds to clear the error and restart calibration. Contact technical support if the error persists.

Maintenance Instructions

Once every quarter, remove the front cover and use a vacuum cleaner to remove dust accumulation inside the heater.

Cleaning should be done while the heater is disconnected from the main service panel. Wait until the housing and heating element cool before performing maintenance.

Replace the front cover before energizing.

A qualified technician should perform any other servicing.
