The ATC Lifestyle Digital Electric Radiator is a modern, state-of-the-art heating appliance designed for efficient and reliable room heating. It features a large TFT-LCD screen with white backlight and black images for ease of legibility, controlled by six touch-sensitive keys.

Function Description:

The radiator operates by heating a special oil contained within its elements, which then radiates heat into the room. It offers multiple operating modes:

Comfort Mode: Allows direct temperature selection between 12°C and 30°C in 0.5°C steps. Ideal for occupied rooms, with a typical comfort temperature of 20-21.5°C.
ECO Mode: Automatically sets a temperature between 0.5°C and 4.5°C less than the selected comfort temperature. This mode is suitable for short periods of absence to prevent excessive temperature drops. The ECO temperature range is 7.5°C to 29.5°C.
Anti-Frost Mode: Maintains a factory-set temperature of 7°C to prevent freezing during long periods of absence.
Program Mode: Allows users to set daily and weekly heating schedules, automatically switching between comfort, eco, or anti-freeze settings in half-hour intervals. The program display shows a 12-hour program around an analogue clock face, with AM and PM screens.
Manual Mode: Enables temporary override of the current settings, allowing the user to force the heater on or off for a set duration (from 0 to 365 days, and in 1-minute or 30-minute increments for hours) and at a desired temperature (7°C to 30°C). After the set time, the radiator reverts to its previous operating mode.

Key Features:

Control Panel: Features a TFT-LCD screen with six touch-sensitive keys for confirming modes, selecting operating modes, entering manual mode, and adjusting settings.
Standby Function: The radiator can be turned on or off by touching and holding the ON/OFF key. In standby, a short beep sounds when any key is touched, and the standby screen appears for 10 seconds.
Memory Function: In case of power failure, the radiator remembers its previous mode of operation, temperature, and on/off state. The day and time are saved for up to 10 years thanks to a button cell battery (CR2032).
Configuration Mode: Allows users to set various parameters, including brightness level at rest (0%, 25%, 65%, 100%), maximum brightness time (1 to 240 seconds), setting the time (hour/day), Open Window function, Adaptive Start Control, and Reset Default.
Open Window Function: When enabled, the system automatically switches off the radiator if it detects a sudden drop in temperature (4°C in 20 minutes), typically caused by an open window or door. This function contributes to energy efficiency.
Adaptive Start Control: In Program mode, this function analyzes the next two hours and calculates when to start heating to efficiently reach the next programmed set-point temperature. It progressively increases the set-point temperature.
Keyboard Lock: The keyboard can be locked by touching and holding the up and down keys for 2 seconds, preventing accidental changes. A padlock icon appears on the screen when locked.
Internal Parameter Configuration: Includes two user-configurable parameters:
- Temperature Offset (Param. 1): Allows adjustment of the probe correction setting (-5°C to +5°C in 0.1°C steps) to calibrate the displayed temperature with the actual room temperature.
- Easy Mode (Param. 2): Offers two settings: 1P (full control over all features) and 2P (simplified control, allowing only temperature adjustment).
Heating Indication: A thermometer symbol filling up in the top right corner of the display indicates when the radiator is actively heating.

Installation Requirements:

Must be installed by a qualified electrician in compliance with current UK and Irish regulations.
Should not be located underneath an electrical connection or light switch.
The electric supply line must be protected with a high sensitivity differential device (RCBO).
Requires a minimum distance of 100mm to curtains, furniture, etc., for proper hot air circulation.
In bathrooms, it must be mounted outside Zone 2 (UK) or Zone 3 (Ireland), with control unit switches unreachable from the bath/shower or wash basin (at least 0.6m away).
A switched spur and a fused connecting box with an appropriate sized fuse are recommended for each heater.
The connecting box should be positioned 10cm to the right of the appliance and 15cm above the floor.
Mounting is done using adjustable brackets fixed to the wall, with a cardboard template provided for drilling holes.

Maintenance Features:

Requires very little maintenance.
Surfaces should be cleaned regularly with PH neutral products; abrasive or granular substances should not be used.
Electric power should be switched off before cleaning.
Failure to keep the radiator clean may lead to dust burning and dark streaks on the wall above the heater.
In case of oil leakage, repairs must only be made by the manufacturer or ATC.
Replacement of the button cell battery (CR2032) for time and day retention should be done by an authorized electrician.

Safety Information:

Do not cover the radiator to prevent overheating.
Do not sit on the radiator.
Not intended for outdoor use.
Damaged power cords must be replaced by the manufacturer, its after-sales service, or qualified persons.
Can be used by children aged 8 years and above and persons with reduced physical, sensory, or mental abilities if supervised or trained.
Children under 3 years should be kept out of reach unless constantly supervised.
Some parts of the product can become hot and cause burns; caution is advised when children and vulnerable people are present.
If discarded, ensure responsible recycling of oil and follow local provisions.
A Safety Data Sheet is available from sales@atc.ie.

Error Notifications:

The device can detect two types of errors:

ERROR1: Failure in microcontroller, EPROM, or other PCB components.
ERROR2: Failure of the NTC probe (e.g., disconnected, short-circuited). Upon recovering from an error, the radiator returns to Stand-by mode and does not retain previous settings.
