Convenient Control

The innovative app will allow you to adjust your Onyx electric fire’s array of Chromalight® Plus visuals and convenient heating settings. For a complete list of options, please see the instruction manual for your fire.

Flame Effects

Depending on the model of electric fire, the app or remote control can be used to adjust the myriad of available flame options to create your perfect ambience.

Ember Bed Up-Lighting

Beneath the logs and ember effects, your fire’s up-lighting LEDs can be set to a range of hues to either compliment or contrast with the flames, with adjustable brightness.

Natural Log Lighting

Nestled within your fire’s lifelike log effect are added lighting effects that illuminate the logs to enhance the fire’s authenticity.


Hidden in the top of your fire’s firebox are discreet down lighting LEDs which illuminate the fuel effects from above, adding to the immersion.

Synchronised Visuals

The Sync feature lets you synchronise the colour of different lighting effects, to easily create a corresponding display.

Quick Start Pre-sets

Need instant ambience? Select from any of your fire's six stunning pre-sets ranging from natural to contemporary. You can also save up to three custom combinations with your preferred settings for easy access.

Optional Mood Lighting

Effortlessly control the optional Mood Lighting system using either the remote control or app. Choose from 13 different colours or the gradually changing Spectrum mode to transition through each colour.

Thermostatic Heating

Choose your preferred room temperature and your electric fire does the rest for you. Select a temperature up to a max of 35°C and the fire’s 2kW heater will adjust its power to reach the desired level as efficiently as possible. Turn off the heat entirely to enjoy just the visuals during the warmer months.

Adaptive Start Control

Adaptive Start allows your fire to automatically turn on up to 45 minutes in advance of a pre-set time to reach the desired room temperature, ready for when you sit down and relax.

Open Window Detection

Should ambient room temperatures drop by 4°C within a space of eight minutes, like when a window is opened, your fire’s heater will automatically turn off to save energy. Heating can be easily resumed with the remote control or app.

Timers and Scheduling

As well as a basic timer function, you can also programme individual day and weekly schedules for both flames and heat. Simply set your start time and end time, and which weekdays you’d like the programme to repeat on, and let your fire do the rest, providing warmth or ambience exactly when you want it.

Ecodesign Compliant

Innovative energy saving features make these fires compliant with stringent Ecodesign energy product standards.
