Setup: Dimplex DHCHA20AR 2kW DC Ceramic Tower Heater with Remote Control Instruction Manual

Overview

The DHCHA20AR 2kW DC Ceramic Tower Heater with Remote Control is a compact indoor heater designed for domestic residential use. Its ceramic heating system provides three heat levels, while ECO mode adjusts heating according to the selected room temperature. A 70-degree oscillation function helps distribute warm air across a wider area.

The upright tower design includes an LED display, electronic controls, a carry handle, and a remote control for convenient operation. Place the heater on a firm, level surface with clear airflow around the air inlet and outlet.

Detailed Description

The ceramic heating element warms air drawn through the air inlet. Heated air leaves through the air outlet at the top section of the tower. The fan supports air movement, while the electronic thermostat and operating modes control heat output.

The main parts are the air outlet, control panel, air inlet, power cord, carry handle, and LED display. The carry handle is intended to help move the heater after it has been switched off and allowed to cool.

The control panel and remote provide matching functions: standby, temperature or heat-level adjustment, oscillation, operating mode, timer, and sound control. The display may enter sleep mode after three minutes without an operation; pressing a control restores the display.

Safety

• Use the heater indoors for household applications only. Do not use it outdoors, in a bathroom, near a bath or shower, beside a swimming pool, or where water may fall onto the appliance.
• Do not operate the heater after it has been dropped or if visible damage is present. Disconnect it if a fault develops.
• Use the heater upright on a horizontal, stable surface. Do not operate it on a slope, uneven flooring, deep-pile carpet, or a long-haired rug.
• Keep the plug accessible and do not position the heater directly below a fixed socket or connection box.
• Never cover the heater or place clothing, towels, textiles, or other objects on it. Keep curtains, fabrics, furniture, and flammable materials at least 1 metre from the air outlet.
• Keep the power cord away from the front of the heater, traffic routes, hot surfaces, and areas where it could be cut or crushed. Do not run it beneath furniture, appliances, carpets, rugs, or runners.
• Do not connect the heater through a timer, programmable controller, thermal control, external switching device, or circuit that repeatedly switches power on and off automatically.
• Do not use an extension lead if it could become overloaded.
• Supervise children and ensure they do not play with the appliance. Hot surfaces can cause burns, so take particular care around children and vulnerable people.
• Do not use the heater in a small occupied room if the occupants cannot leave independently unless constant supervision is provided.
• Do not attempt DIY repairs. A damaged supply cord must be replaced by the manufacturer, an authorised service agent, or a suitably qualified person.
• Disconnect the plug when the heater is not needed for a long period. Keep the appliance away from chemicals, naked flames, foreign objects, and conditions that could damage the power cable.

Built-In Protection

A tilt switch prevents operation if the tower is accidentally knocked onto its side. If this happens while the heater is hot, disconnect the power, allow the unit to cool, and carefully return it to an upright position before reconnecting it.

An overheat limiter switches the heater off if its temperature becomes excessive. Disconnect the appliance and let it cool for at least 30 minutes. Before restarting, remove the cause of restricted airflow or overheating.

Setup and Operation

Initial Setup

1. Place the heater upright on a level, stable surface with unobstructed airflow.
2. Unwind the power cord fully and keep it positioned away from the front of the appliance.
3. Plug the heater into a suitable power socket. The standby button illuminates.
4. Press the standby button once to begin operation.

Press the standby button again to switch the heater off. The unit continues a 30-second shutdown cycle to clear warm air before returning to standby, accompanied by a short beep.

Control Functions

• Standby: Starts or stops the heater. Standby and power-off states retain the last operating settings.
• Mode: Cycles through ECO, Fan Only, and Heat modes.
• Heat levels: In Heat mode, use the plus and minus controls to select H1 low, H2 medium, or H3 high heat.
• Temperature: In ECO mode, set the target between 5°C and 35°C in 1°C increments. The selected value is accepted after the display flashes three times.
• Oscillation: Press the oscillation control while operating to sweep the heater from side to side. Press it again to stop movement.
• Timer: Press Timer, then use plus and minus to select 00 or a period from 1 to 12 hours in one-hour steps. The 00 setting disables timed operation.
• Mute: Press the mute button on the remote to turn operating sounds off or on.
• Child lock: Hold the Timer button for three seconds to lock the controls. Repeat the three-second hold to unlock them.

ECO Mode

ECO mode compares the target temperature with the surrounding temperature and selects an appropriate output. When the temperature difference is greater than 2°C, the heater uses high power. When the difference is 2°C or less, it uses low power.

When the target and room temperatures are equal, the fan continues for approximately 30 seconds to clear residual warm air before the heater enters standby. Heating resumes when the temperature difference reaches at least 2°C. If the difference rises above 4°C, high power is selected.

Fan Only and Silent Operation

Fan Only mode circulates air without heating. To activate silent operation, hold the Mode button for three seconds or use the remote mute control. Hold the Mode button for another three seconds to restore operating sounds. In silent mode, Fan Only is represented by “--” on the display.

Automatic-Off Setting

While the heater is on, hold the plus and minus controls together for five seconds to disable the automatic-off function. The heater beeps three times and displays “24/00.” Repeat the same five-second action to enable the function again.

Remote Control

The remote control provides the same primary settings as the heater’s control panel. To install the batteries, slide open the rear cover, insert two AAA batteries in the indicated orientation, and close the compartment.

Cleaning and Maintenance

Dust can restrict airflow and reduce heating performance. Clean the DHCHA20AR at least once a month, or more often in dusty rooms.

1. Switch the heater off and unplug it from the power socket.
2. Remove loose dust with a soft brush.
3. Wipe the housing with a soft, slightly damp cloth. Use mild detergent for stubborn marks.

Do not allow water or any other liquid to enter the control panel or contact other electrical parts. Never immerse the heater.

Storage

For extended storage, switch the control off, unplug the heater, and clean it before putting it away. Cover the appliance and store it upright in a dry location away from direct sunlight. Long-term sunlight exposure may discolour the housing.

Troubleshooting

• The heater will not start: Check that the plug is firmly connected and that the power socket is working. Confirm that the heater is upright, since the tilt switch prevents operation when the unit is on its side.
• The heater stops while operating: Disconnect it and allow it to cool for at least 30 minutes. Check that the air inlet and outlet are clear and that the heater has not been covered.
• The heater produces less warmth: Remove dust from the air inlet and outlet, confirm that the selected heat level is suitable, and ensure curtains or furniture are not blocking airflow.
• The controls do not respond: Check whether Child Lock is enabled. Hold the Timer button for three seconds to release the lock.
• The display is blank: Press a control to exit display sleep mode. The display may turn off after three minutes without input.
• The heater does not oscillate: Press the oscillation button while the heater is operating. Check that the oscillation indicator is active and that the unit is standing level.
• The remote does not operate the heater: Replace or correctly reposition the two AAA batteries and aim the remote toward the heater’s control area.
• The appliance remains faulty or damaged: Unplug it and do not continue operating it. Do not dismantle or repair the unit yourself.

Recycling and Disposal

Do not dispose of the heater with unsorted household waste. Electrical appliances should be taken through an appropriate separate collection system. Correct disposal helps prevent harmful substances from entering soil and groundwater.
