Electrical connection

WARNING – THIS APPLIANCE MUST BE EARTHED

The use of an extension lead or multi-plug adaptor is not advised when

connecting this product to the mains. Connection through these devices

could lead to a risk of overloading, overheating and even re at the extension

lead or adaptor due to inadequate connection quality.

This heater must be used on an ~ supply only and the voltage marked on
the heater must correspond to the supply voltage. This heater is tted with

a rewireable plug incorporating a 13 amp fuse. In the event of replacing
the fuse in the plug supplied, a 13 amp fuse approved by ASTA to BS 1362
must be used. If any other type of plug is used, a 15 amp fuse must be

tted in the plug, the adaptor, or at the distribution board.
IMPORTANT : If the plug is not suitable for your socket, the 13 amp plug

should be removed. Before wiring the appropriate plug, please note that
the wires in this mains lead are coloured in accordance with the following
code : GREEN AND YELLOW: EARTH

BLUE : NEUTRAL
BROWN : LIVE

Connect the GREEN AND YELLOW wire to the terminal marked ‘E’ or
by the earth symbol , or coloured GREEN or GREEN AND YELLOW.
Connect the BROWN wire to the terminal marked ‘L’ or coloured RED.
Connect the BLUE wire to the terminal marked ‘N’ or coloured BLACK.

WARNING: DO NOT USE THE HEATER UNTIL THE FEET ARE
FITTED CORRECTLY.

The product is intended for occasional use as a portable unit. Please ensure

the feet are securely tted before the product is used. Once the feet have
been installed simply plug in and switch on at the wall socket.
Please note – the element has been coated with a protective lm which
will burn off during the rst few minutes of use and may cause a small
amount of fuming. This is quite normal – the fumes are non-toxic and will
quickly disappear.

We recommend that you open a window to ventilate the room when using

the heater for the rst time.

Positioning the heater

Always ensure that the heater is stood on a rm, level base near to, but
not directly beneath, a suitable mains supply socket.

Ensure that curtains and furniture are not positioned close to the chosen

position, as this would create a potential re hazard.

Assembling the foot

WARNING: THE HEATER SHOULD NEVER BE USED WITHOUT THE
FEET SECURELY FITTED.

In both MANUAL and AUTO mode there are three heat settings options:

‘Intelligent’ Eco Mode - This is the initial default setting, the convector will

automatically start up in this setting once power is applied. The convector
will automatically regulate the room temperature accordingly. In this mode
the convector operates at full power, however the output of the convector is
automatically reduced and regulated as the room temperature approaches
the desired level. This mode optimises energy use by calculating the most

efcient and effective way to achieve the desired temperature setting. The

desired room temperature can be adjusted at any time during operation by

pressing the appropriate key.

Low Heat - In this option, the appliance will operate at a low heat setting,
the appliance will automatically cycle at this setting to maintain the room
temperature setting.

High Heat - In this option, the appliance will operate at a high heat setting,
the appliance will automatically cycle at this setting to maintain the room
temperature setting.

Lay the heater on its back. Locate and remove the foot xing screw - see

Fig. 2(a). Clip the foot in place and secure using the foot xing screw.

The appliance has a frost protection mode. This setting is useful in areas
such as garages to assist in the prevention of frost damage. In Manual

mode, if the thermostat is set to its minimum setting ‘5°C’, the heater will

Heat Neon: Heat neon remains on when the heating element is active.
Once the desired temperature is reached and the element turns off, the
heat neon will indicate this by remaining off.

Bluetooth Neon: The Bluetooth neon will remain illuminated while
successfully paired to another device.

Setting the Timer Programmes

There are four program segments available, P1, P2, P3 and P4. For each

segment it is possible to set a desired ‘On’ time, ‘Off’ time, Heat mode

and set temperature. It is not necessary to set all four segments if not
required. The default setting is for all segments to be Off. To turn off a pre-

programmed segment it is necessary to set both the ‘On’ time and the ‘Off’
time to 00:00. In order to set up a time/temperature prole the following

steps must be completed:

1. To activate the programming screen press the ‘ ’ key. The program

using the ENTER key.

4. The ‘Off’ time must then be set by using the arrow keys, it is necessary

to then press the ENTER key to conrm the ‘Off’ time setting.

5. The setup screen will then revert to the P1 ‘On’ time set up screen, at
this point it is possible move to the P2 segment by pressing the ‘ ’ key.

6. If required P2, P3 and P4 segment can be set up using steps 1-4 above.

7. If it is not required to set up P2, P3 and P4 segment at this stage, continue

to press the ‘ ’ key until the heater reverts to the previous operational mode.
Alternatively if no keys are pressed the programming mode will time out

and revert to the previous operational mode.

Remote Bluetooth Operation

The appliance can be controlled remotely using a smartphone or similar

device. To facilitate this remote operation it is necessary to rst download
the Dimplex app. The app is available on both android and IOS

devices and is available free from the Apple or Android App store. The

with the smartphone to complete the remote setup. Please follow the steps

shown below:

1. Launch the Dimplex app on the smartphone or similar device.

2. To initiate pairing mode on the appliance press and hold the ‘ ’ button
for two seconds. The LCD screen will go blank with the exception of the

Bluetooth logo ashing in the bottom right hand corner, See Fig.11.This
indicates that the device is advertising to be paired with the app.

3. On the smart phone the appliance should now be visible on the pairing
screen, this will be a unique 6 digit code but will always start with EC, for

example ‘ECBC17’. Select this device and press connect to initiate pairing.

4. Once the paring process is complete the app can be used to control
the appliance.

5. Once paired successfully the Bluetooth logo will stop ashing and the

Bluetooth neon will be illuminated.

Setting the Desired Temperature

The desired temperature can be set using the ‘ ’ or ‘ ’ keys. The
temperature can be set from 5˚C to 30˚C and this will be shown on the

display. When the temperature is reached the heater will automatically
switch OFF. If the ambient temperature drops the heater will come on
again automatically.

Safety – overheat protection

For your safety, this appliance is tted with a thermal cut-out. In the event

that the product overheats, the cut-out switches the heater off automatically.

To bring the heater back into operation, remove the cause of the overheating,

then unplug or turn off the electrical supply to the heater for a few minutes.

When the heater has cooled sufciently, re-connect and switch on the

heater.

Important Notes

Although this heater is manufactured to comply with the relevant safety
standards, certain types of carpets could become discoloured by the
temperatures under a portable heater. If you are concerned about this,
we recommend that you contact the carpet manufacturer for guidance.
Alternatively, either stand the heater on a suitable base to shield the carpet
– call our Helpline for further advice.
You may notice some parts of the element appearing to be hotter from time

to time because of the variable airow through the heater. This does not

cause a safety hazard.
The heat outlet grille may become discoloured with use – this is caused by

airborne pollution and is not a fault.
