The LED number display shows the detected room temperature during normal operation and can be switched between Celsius and Fahrenheit.

The control panel contains the setting button, up and down buttons, power button, heating indicator, low- and high-heat indicators, timer indicator, temperature-unit indicator, LED display, display on/off control, heat-level selector, and WiFi status indicator. When WiFi is connected, its indicator remains illuminated; when connection fails, the indicator flashes.

Safety

• Use only the voltage shown on the heater rating plate.
• Use the appliance indoors and only in a dry location. Do not use it outdoors, on wet surfaces, or near a bath, shower, swimming pool, or other liquid source.
• Keep the air inlet and outlet clear. Do not cover the heater or place objects against its grilles.
• Maintain at least 1 metre of clearance from the front, sides, and rear of the appliance.

• When used with the foot set, keep the heater away from baths, showers, swimming pools, and other wet areas.
• When wall mounted near a wet area, do not touch the control unit while the heater is operating.

Setup and Operation

Initial Setup

1. Remove the heater carefully from its carton and retain the packaging for seasonal storage.
2. Confirm that the power switch is set to OFF.
3. Assemble the heater completely using the mounting instructions. It may be installed on a wall or operated in freestanding mode with the appropriate foot set.
4. Place the heater upright with its airflow openings unobstructed.
5. Connect the plug to a suitable mains outlet. Avoid using the same outlet as another high-power appliance.

Powering On

1. Turn on the power switch after confirming that the heater is correctly assembled and positioned.
2. The heater enters standby mode and the control buttons become available.
3. Press the power button to start operation. The display shows the current room temperature.

Setting the Temperature

1. Press the setting button once. The temperature indicator flashes to show that adjustment is active.
2. Use the up and down buttons to choose the desired temperature.
3. Save the selection using the setting control. The heater begins heating when required, and the heating-element indicator illuminates.

Selecting Heat Output

• In working mode, press the up button to switch between high heating and heating off. The high-heat indicator lights during high-power operation.
• Press the down button to switch between low heating and heating off. The low-heat indicator lights during low-power operation.
• Use the heat-level selection control to cycle through off, low, and high heating.

Timer Operation

The timer can start heating when the heater is off or stop heating while the heater is already operating. The selectable period is from 0 to 24 hours.

1. To schedule a start, leave the heater in heating-off mode and press the setting button twice.
2. Use the up and down buttons to select the timer period and target temperature.
3. To schedule a stop, start the heater at either heat level and press the setting button twice.
4. Set the required period and temperature using the up and down controls.
5. The timer indicator remains lit during the active timer period and goes out when the timer finishes.

When a delayed start ends, the heater begins heating at the high level. When a stop timer ends, heating stops.

Child Lock

While the heater is operating in heating mode, press and hold the up and down buttons together for approximately 3 seconds. The controls become locked and settings cannot be changed. Repeat the same action for about 3 seconds to unlock the panel.

Display and Energy-Saving Functions

• The control lights normally switch off while the heater is running. Touch the panel area below the temperature display to reactivate them.
• Select ECO mode to turn off the LED display while the heater continues operating.
• Press the two left-hand keys together for approximately 10 seconds to change the displayed temperature between Celsius and Fahrenheit.

Open-Window Detection

If the detected room temperature falls by 3°C or more within 2 minutes, the heater activates open-window detection and stops heating. The temperature indicator flashes. Press the power button to switch the heater off, then turn it on again to cancel this function and resume normal control.

WiFi Function

The MPH-20041S Slimline Panel Heater with WiFi Function can be paired with a compatible smart-home application for remote control and scheduling. The WiFi indicator provides connection status: a steady light indicates a successful connection, while a flashing light indicates that connection has failed or setup is incomplete.

1. Ensure the heater is in heating mode.
2. Press and hold the setting button for approximately 5 seconds to reset or activate the WiFi pairing state.
3. Check that the WiFi indicator is flashing before beginning setup in the mobile application.
4. Connect the mobile device to a compatible 2.4 GHz WiFi network. A 5 GHz network is not supported.
5. Follow the application prompts to add the heater, select the home network, and enter its password.

If pairing fails, verify the password, confirm that the mobile device and heater are within reliable network range, and check that the router uses WPA2-PSK encryption with AES protocol.

Turning Off

Press the power button to stop the heater. Allow it to cool before moving, cleaning, or storing it. Disconnect the plug from the mains if the appliance will not be used.

Cleaning and Maintenance

1. Switch the heater off and unplug it from the mains.
2. Wait until the appliance has cooled completely.
3. Wipe the exterior with a damp cloth. The cloth should not be wet.
4. Use a vacuum cleaner to remove dust and fluff from the grilles and ventilation areas.
5. Do not use abrasive cleaners or allow water to enter the heater.
6. Make sure the appliance is fully dry before reconnecting it to power.

Regularly removing dust from the grilles helps reduce overheating caused by accumulated dust or lint.

Troubleshooting

• The heater does not start: Confirm that it is fully assembled, the power switch is on, the plug is firmly connected, and the outlet is supplying power. Check whether a timer, child lock, or open-window detection function is active.
• The heater stops heating unexpectedly: Check whether the timer has ended or open-window detection has activated. A rapid temperature decrease of at least 3°C within 2 minutes can trigger the latter.
• The controls do not respond: The child lock may be active. Hold the up and down buttons together for approximately 3 seconds to unlock the panel.
• The WiFi indicator flashes: Reset WiFi by holding the setting button for approximately 5 seconds, then repeat pairing on a supported 2.4 GHz network.
• The display is not visible: Touch the panel area below the temperature display. ECO mode may also have switched the LED display off.
• The heater appears to overheat: Switch it off, unplug it, and allow it to cool. Check that the grilles are clear, the heater is not covered, and dust has been removed with a vacuum cleaner.
• The cord or plug is damaged: Stop using the appliance and arrange replacement by a qualified service professional.

Storage and Disposal

Clean the heater and allow it to cool completely before extended storage. Store it in a cool, dry location, preferably in its original carton. Do not store the appliance while it is still hot.

At the end of its service life, dispose of the heater through an appropriate electrical and electronic equipment collection or recycling facility rather than with ordinary household waste.
