Model Number: CN2MLSTiERF

All electrical appliances produced for the Company are guaranteed for one year against faulty material or workmanship. This applies only if the appliance has been used for purposes in accordance with the instructions provided and has not been connected to an unsuitable electricity supply, or is subject to misuse, neglect, damage or modified orrepaired by any person not authorized by us. This guarantee is offered to you as an extra benefit and does not affect your legal rights. The correct electricity supply voltage is shown on the rating label attached to the appliance. Reasonable care has been taken to ensure that this guide is accurate at the time of printing. In the interest of progress the Company reserve the right to vary specifications from time to time without notice.

General Safety

Our Low Surface Temperature heaters have been designed and built to the NHS requirement for safe surface temperatures which is that no surface which can be touched by the user will be more than 43 ºC (at a room temperature of 21 ºC) This means that our Low Surface Temperature heaters out-perform the European Standard by a significant margin. The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities or lack of experience and knowledge unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

Safety Monitor

As part of the intelligent control (see section 15), the heater has built-in safety monitoring. In the unlikely event of a fault, safety monitoring will help prevent high surface temperatures. The safety monitor will identify overheating, fan failure, and certain electronic faults. When the safety monitor identifies a fault, the heater runs in restricted mode. However, in the event of a serious fault, the heater stops running. The heater indicates a fault by beeping twice. It will not beep again until the unit is switched off and then back on, but the LED will flash red continuously. Thermally Operated Cut-Out The appliance is fitted with a thermally operated cut-out (TOC). In the unlikely event that the safety monitor fails, this safety device will switch the heater off if the appliance overheats. If the TOC has tripped there is a high possibility the heater is faulty and should be checked by a qualified person. The TOC can only reset after the appliance has cooled down. However, we advise you not to do this until the heater has been checked. In order to re-set the TOC, proceed as follows:

Switch off the appliance and leave for approximately 10 minutes.
Switch appliance back on and the TOC will re-set.
Ensure that the appliance is functioning correctly. If the TOC control operates again, the appliance should be checked by a qualified person.

The heater carries a ‘Do Not Cover’ label to warn the user that if the appliance is covered, it will overheat.

Press and hold TIME and TEMP together for 5 seconds. The display will show symbols. Repeat the step to unlock.

Open Window Detection

Ensuring you don’t waste energy on heating the outside world, the heater is equipped with optional open/closed window detection. The heater recognizes sudden drops in temperature when a window or a door is opened and turns the heating off to save energy. When the window is closed, the heater will automatically detect a temperature rise and switch itself back on. Once enabled in the setup menu, the open window detection is fully automatic and does not require any human intervention to be activated.

Setting-up Open Window Detection

The system has been factory set to default time and temperature values. If necessary, all values can be adjusted. When the heating is on, the open window detection sensor will automatically switch the heater off when it detects a fall in temperature of 2°C in less than 10 minutes (this temperature can be changed in menu 7 and time in menu 6). If a temperature rise of 2°C in less than 30 seconds is detected, the heater will switch itself back on (this temperature can be changed in menu 9 and time in menu 8).

Press and hold TEMP and MODE together for 5 seconds.
The display will enter the setup menu.
Use TEMP and MODE to change a value.
Use TIME to scroll between the settings.

temperature calibration

The temperature reading has been factory calibrated but if for any reason it needs adjusting (better accuracy required, to suit the different positions in the room, etc.), the reading can be recalibrated in 0.5-degree steps.

Intelligent Fan Control

The intelligent fan control incorporates one of the latest low-energy consumption BLDC motors. This allows the heater to operate quietly, whilst still providing the best possible levels of comfort. Depending on which heat mode is activated, it will calculate the best possible airflow temperature and will adjust the fan speed accordingly. If the heater is running in fan mode only (heat switched off), then the fan will operate at a fixed speed.

Mounting

This unit is for wall mounting only. It is designed to be very quiet in operation if mounted correctly. When fitting more than one heater into a room we would recommend that they are sited on the same wall to optimize airflow and ensure quiet operation.

MOUNTING ON A PLASTERBOARD WALL

Where the heater is fitted onto the plasterboard only, ensure plasterboard fixings are used. Standard wall plugs will not be suitable.
Where possible mount the heater(s) on an outside wall to inhibit the transfer of sound within the building.

NB: Failure to follow the instructions and recommendations provided could result in increased noise levels.

To wall mount follow the below steps

Mark screw fixing positions on the wall in accordance with dimensions shown on Fig.1 on page 3.
Drill 4 holes for 8mm wall plugs.
Insert plugs into the holes.
The two keyhole screws can be now screwed in until the heads are approximately 2mm from the wall.
Position the appliance on the partially inserted wall screws
Secure wall brackets to the wall

Cleaning

Always disconnect the heater from the mains before cleaning. The heater should not require any maintenance, but it is strongly advised that it is kept clean. An occasional wipe-over with a soft cloth is all that should be necessary.

Do NOT use metal or furniture polish on any part of the heater.
Do NOT touch the heater with wet hands or in any way bring water into contact with it.

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or a similarly qualified person in order to avoid a hazard.

Connection to the Main Supply

Electrical installation should be carried out by a competent installer, preferably registered with NICEIC (National Inspection Council for Electrical Installation Contracting) in accordance with the 17th edition of the IEE Wiring Regulations, (BS.7671), and any relevant Local Authority Bye-Laws. This heater is fitted with a 3-core mains supply cable and should be permanently connected to the electricity supply via a double pole switch having 3mm gap on each pole. A switched Fused Connection unit to BS.1363. Part 4 is a recommended mains supply connection accessory to ensure compliance with safety requirements applicable to the fixed-wiring installation.

Note: When switched on for the first time the appliance may emit a slight smell. This is purely the evaporation of a fluid used in the manufacturing process.

If Your Heater Does Not Work

Check that power is available to the heater. The LED in the control switch should be illuminated.
Check that the thermal cut-out has not operated. Follow the reset instructions given under the section headed ‘Thermal Operated Cut-out’.
Check that the fuse in the spur unit has not blown. This can be done by replacing the fuse with another suitable fuse.

Should none of the above remedies work, then telephone the helpline number shown in these instructions (UK ONLY). Do not attempt to repair the heater.

Connection to MRX1

The CN2MLSTiERF is compatible with the MRX1 multi-zone controller. To pair the CN2MLSTiERF with the MRX1, set the MRX1 to pairing mode (see section 10 of MRX User Instructions).
