Frequently Asked Questions - OFC2000Ti DIMPLEX

How do I set the thermostat on my Dimplex OFC2000Ti?

Turn the thermostat dial clockwise to increase the desired temperature. The heater will cycle on and off to maintain the set temperature. For frost protection, set the dial to the snowflake symbol.

The heater is not turning on. What should I check?

First, ensure the unit is plugged into a working outlet and the power switch is on. Check if the thermostat is set above room temperature. If still off, press the reset button on the plug (if equipped) or check for a tripped circuit breaker.

Can I use an extension cord with the OFC2000Ti?

It is not recommended. If necessary, use a heavy-duty extension cord rated for at least 15 amps and fully unwound to prevent overheating. Always plug directly into a wall outlet when possible.

How do I clean my oil-filled radiator?

Unplug the heater and let it cool completely. Wipe the exterior with a soft damp cloth. Do not use abrasive cleaners or immerse in water. Ensure the air vents are free of dust.

What safety features does the OFC2000Ti have?

The heater includes overheat protection (thermal cut-off) and a tip-over switch that automatically shuts it off if accidentally knocked over.

Why does my heater make a clicking sound?

Clicking sounds are normal as the thermostat switches the heating element on and off to maintain temperature. The metal fins may also expand and contract, causing mild noises.

Can I paint the radiator fins?

No, painting the fins can reduce heat output and may create a fire hazard. The factory finish is designed for optimal performance.

What is the maximum room size for this heater?

The Dimplex OFC2000Ti is suitable for rooms up to approximately 20 square meters (215 sq ft), depending on insulation and climate.

How do I store the heater when not in use?

Allow the unit to cool, wipe it clean, and wrap the cord around the built-in cord storage. Store in a dry, dust-free place. If possible, keep it upright.

Where can I find spare parts for the OFC2000Ti?

Spare parts such as thermostats, switches, and castors are available through Dimplex authorized service centers or online retailers. Check your user manual for part numbers.

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.

Fitting the castors

The castors can only be fitted between the outer fins (as shown in Fig. 2).

Turn the radiator upside down on a carpet or other soft surface to avoid damage

WARNING : THE RADIATOR IS HEAVY – ENSURE THAT IT IS SUPPORTED TO PREVENT IT FROM TOPPLING. Ask a second person to help with this if necessary. Locate the wire clamps and remove the winged nuts (see 'C') in Fig.3A. Insert the non threaded end of the wire clamp 'A' into one of the holes in the castor plate 'B' as shown in Fig.3A, at the same time tilting the opposite end of the plate slightly. Lower the castor plate and insert the threaded end of the clamp through the fins and over the boss and into the other hole in the castor plate. Place the winged nut 'C' on the thread and tighten it securely.

Repeat the process for the other castor bracket onto the last fin. Note: The 9 and 11 fin column radiator models - use straight castor brackets and must be fitted as shown in Fig.2.

Lift the radiator clear of the floor, then turn it back upright and stand it on its castors as shown in Fig.1 and Fig.3B. It is now ready for use.

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 plugged into the mains.

Controls

Thermostat (see Fig.4)

The Thermostat (see Fig.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 (see Fig.5)

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

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

The timer allows you to select 'AUTO' or 'MAN ON' by pressing the 'MODE' button until the required MODE appears at the bottom of the timer display.

'AUTO' MODE allows the heater to switch ON and OFF according to a set 24 Hour program period (see 'Setting Programs' section below).

'MAN ON' MODE allows power to the heater uninterrupted by the program settings.

Key Lock:

If 'ENTER' and 'MODE' are pressed within 1 second, the keys will be locked. The user will know the keys are locked as the lock symbol '0-' will be displayed on the top left hand corner of the screen. To unlock the keypad, press 'ENTER' and then 'MODE' within 1 second.

Initial Operation

For initial use, plug the heater into a regular household power point and turn the power on. The timer is now ready to be set up for use.

Setting Current Time

1. Hold the 'PROGRAM' button until the clock symbol 🔒 appears on the screen. The user can now set the clock.
2. The hour digit will flash. To adjust the hour use the '-' & '+' buttons. Confirm the hour digit by pressing 'ENTER'.
3. Once 'ENTER' has been pressed the minutes will flash. To adjust the minutes use the '-' & '+' buttons. Confirm the minute digit by pressing 'ENTER'.
4. The timer now returns to the default display.
5. To reset incorrect time, repeat previous steps.
   Once the correct time is set, a total of four ON/OFF time programs can be set for operation.

Setting Programmes

Press the 'PROGRAM' key to set the programs.

You are now setting the programs starting with P1 'ON'.

SETTING P1 ON TIME:

1. To set the hour use the '-' & '+' buttons. Confirm the hour digit by pressing 'ENTER'.
2. To set the minutes use the '-' & '+' buttons. Confirm the minute digit by pressing 'ENTER'.

Note: The minutes can only be set in 10 minute blocks in programme 'MODE'.

SETTING P1 OFF TIME:

1. To set the hour use the '-' & '+' buttons. Confirm the hour digit by pressing 'ENTER'.
2. To set the minutes use the '-' & '+' buttons. Confirm the minute digit by pressing 'ENTER'.

Repeat steps 1 to 4 to programme P2, P3 & P4. After programming P4 'OFF' you automatically exit to the default display.

At any time while programming the timer you can press the 'PROGRAM' button to exit to the default display.

Note: If the ‘ON’ time is the same as the ‘OFF’ time the appliance will ignore the program.

The Advance Function

When in 'AUTO' MODE, if the '+' button is pressed for longer than 2 seconds the programme will ADVANCE to the next setting programmed and will only revert back to the program when the subsequent programme time is reached. When the 'ADVANCE' function is running the 'ADVANCE' segment will be displayed on the LCD screen. If the '-' button is pressed 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.

Electromechanical Timer Operation (selected models only, see Fig. 6b)

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. 6b). The 24-hour clock is used ; e.g. time shown for 4 pm is '16' (16:00hrs).

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.

Note: each segment represents 15minute period

Safety in use

This appliance incorporates a number of safety devices. In addition to the ‘Important Safety Advice’ section your attention is drawn to the following;

Tilt Switch

The tilt switch will prevent the heater from working if it is accidentally tipped over on its side.

If the radiator is tipped over while it is hot, disconnect the power and allow it to cool, then stand the radiator back upright. Reconnect the power - normal operation should be resumed.

Safety Overheat Protection

The heater is fitted with a thermal safety cut-out which will switch off the heater should it overheat for any reason. If the cut-out operates it is the result of abnormal overheating, and customer services should be contacted for further advice - see 'After Sales Service'.

Storage

If the radiator is not required for long periods, for example during the summer, it should be stored in a dry place and preferably covered to prevent the accumulation of dirt and dust. The supply cord should be neatly coiled around the cable wrap (see Fig. 1) and the plug should be inserted in to the plug pin holes provided in the cable wrap.

IMPORTANT

The heater must be kept plugged in at the mains to retain the time and the programmed settings. If unplugged from the mains, resetting the time and the programmed settings will be necessary.
