Electrical

WARNING – THIS APPLIANCE MUST BE EARTHED

If the socket outlets in your home are not of the 13 amp BS1363 type
they will not accept the plug connected to this heater, therefore cut off
the plug. When cut off this plug can constitute a shock hazard if
inserted into a socket outlet. It must therefore be disposed of safely.

Before wiring the appropriate plug please note that the wires in this
mains lead are coloured in accordance with the following code:

GREEN/YELLOW : EARTH
BLUE : NEUTRAL
BROWN : LIVE

Connect the Green/Yellow wire to the terminal marked E or the earth
symbol or coloured Green or Green/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. DO

NOT connect the Brown (Live) or the Blue (Neutral) wires to the Earth
terminal of your 13 amp plug. If the terminals of the plug are unmarked
or you are in any doubt, consult a qualified electrician.

CAUTION: If you use this heater in conjunction with a thermal control,
programme controller, timer or any other device which switches the
heater on automatically observe all safety warnings at all times.

Positioning the Heater

Select the position for the radiator ensuring there is clearance from any
furniture and fittings of at least 300mm above the heater and 150mm
each side. The radiator should only be operated on a flat stable surface.

Operation

Important – Objects or clothing must not be placed on this heater. Before
using the heater ensure that all warnings and instructions have been
read carefully.

To bring the heater into use plug it in. Neon indicating lights located at
the controls area will glow when the appliance is actually heating.

Controls

Thermostat (ROF2T, ROF2TI & ROF2ETI models only)

The Thermostat (see ‘T’ in Fig.’s 2, 3 & 4) controls the heat output
according to the room temperature. This ensures that the heater will not
produce heat unnecessarily when the room is warm. To set the
temperature you require, turn the thermostat knob clockwise until the
required setting is reached. Alternatively to heat a cold room quickly,
turn the thermostat knob up fully. When the room has reached the desired
temperature, turn the thermostat knob anti-clockwise until the thermostat
just clicks off. The heater will now automatically operate at this
temperature. The thermostat also has a frost protection setting marked

‘ ‘. This setting is useful in areas such as garages, to prevent frost

damage. If the thermostat is set to its minimum setting ‘ ’, the heater
will cycle on and off to maintain a temperature of approximately 5° to
help protect against frost.

Note – Should the heater fail to come on when the thermostat is at a
low setting, this may be due to the room temperature being higher than
the thermostat setting.

Heat Selector Switches (ROF2T, ROF2TI & ROF2ETI models
only)

Selector switches located on the control panel provide a choice of low
heat, high heat or boost heat output to suit varying conditions and for
economy of operation.

Low Heat Setting ‘ ’ - This switch as shown in Fig.’s 2, 3 & 4 provides
a low heat output when activated. When it is activated a neon light ‘x’

illuminates below the control button.

High Heat Setting ‘ ’ - This switch as shown in Fig.’s 2, 3 & 4 provides
a high heat output when activated. When it is activated a neon light ‘x’

illuminates below the control button.

THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE

Dimplex Oil filled Covered Radiators

Models : ROF2T, ROF2TI, ROF2ETI, ROF2ECC and ROF3ECC

Boost Heat Setting ‘ ’ – This switch as shown in Fig.’s 2, 3
& 4 provides the boost heat output. When it is activated a neon light ‘x’

illuminates below the control button.

Note – With the 3 selector switches activated the maximum output of
this radiator can be achieved.

Manual Timer Operation - see ‘y’ in Fig. 3
(ROF2TI models only)

Set the I - - slide switch on the timer (Fig. 6) to :

Position - Heating Off

Position I - Manual operation

This setting allows power to the heater uninterrupted by the timer
settings. The heat selector switch will control the output (see ‘Controls’).

Position - ‘Auto’ operation

DO NOT disconnect this heater from the mains supply unless it is being
taken out of use (e.g. in summer or for storage), otherwise the timer
clock will stop.

Setting the time of day

To set the time of day, rotate the timer dial clockwise (indicated by the
arrow) until the correct time of day is opposite the reference mark

(see Fig. 6). The 24-hour clock is used ; e.g. time shown for 4 pm is ‘16’
(16:00hrs).

Setting the ‘Auto’ ON and OFF times

To set the timer :

1. Using your finger tip or the tip of a pencil, push in as many segments

as necessary around the dial, according to the times you don’t require
heat – see Fig. 7. Each segment pushed in switches the heater OFF for
that part of the hour. All other segments will be ON. For example, Fig. 9

shows the timer set to switch the heater ON between 9.00am and 4.00pm
and between 9.30pm and 7.00am.

2. You can select as many ON periods as you like, within the 24-hour
day. The settings will repeat every day until changed.

3. To change ON and OFF times, simply push in any ‘ON’ segments
you wish to cancel and pull out new ‘ON’ segments as required.

Switching to auto

Set the heat selector and thermostat for the heat output required.

Check that the clock shows the correct time of day. Set the I - -

slide switch to (see Fig. 8) - the heater will switch ON and OFF
according to the timer settings (see Fig. 9).

IMPORTANT NOTES

Remember to observe all safety warnings when operating the heater on
auto setting unattended or attended .

If the mains supply to the heater is interrupted, the timer clock will stop
until power is restored ; reset the time of day to ensure correct ON and
OFF times.

when the ‘ADVANCE’ programme is running the ‘ADVANCE’ feature
will be automatically cancelled and the programme will run as normal.

Note - Timer Memory Back Up Batteries - Once the heater has been
left plugged in with the socket switched on for at least 72 hours the
timer’s memory back up batteries will be fully charged.

Once the timer batteries are fully charged, if there is a power cut or
if the heater is disconnected from the mains for less than six months,
then the timer will continue to keep time & the settings in the memory
will remain intact.
If however the timer back up batteries have not been charged fully, or
if the heater is deprived of power for longer than six months, then the
time and the programme settings are likely to be lost and you may
therefore need to reset the time and the programme before using the
AUTO MODE again.

Electronic Climate Control - see Fig. 5

(ROF2ECC & ROF3ECC models only)

Operation

The electronic control allows MANUAL and AUTO operation. In manual
