Thermostat Operation
The heater is fitted with an adjustable thermostat enabling
the room temperature to be controlled by adjusting the setting
accordingly. The *setting represents a room temperature of
approximately 5°C and may be used for protection against
frost. Higher temperature settings range from 1-6 (max.)
creating a room temperature of approximately 30°C.
A neon indicator light glows when the appliance is actually
heating.
Switch on the heater and turn the thermostat knob to mark 6
opposite the indicator mark (located on centre right of the
knob - see Fig. 4 & 5), and set selector switch to full heat
output to warm the room rapidly. When the room temperature
has reached the desired level, turn the thermostat knob back
slowly until the thermostat just clicks off. The heater will then
maintain the room temperature at the chosen level, provided
that the correct size of heater has been selected for the room
to be heated.
NOTE – Should your heater fail to come on when the
thermostat knob is at a low setting, this may be due to the
room temperature being higher than the thermostat setting.
Operation - TI and TX Timer Models
Control of Output and Temperature (see Fig. 5)
The slide switch on the timer unit controls the electricity
supply to the heating elements on TI and TX models.
The switch marked I- II (half heat – full heat) provides a

during set ‘ON’ periods under the control of the thermostat.
To set the timer’s ‘ON’ and ‘OFF’ periods:
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. 6. Each
segment pushed in switches the
heater OFF for that part of the hour.
All other segments will be ‘ON’.
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.
Note: On TI models each segment on the timer represents
20 mins.
TX Models
TX Models are fitted with 7 day programmable timers. In all
other respects they are identical in installation and operation
to 24 hour timer operation on TI models.
1. Setting the Time
The current day and time is set by rotating the timer dial
clockwise until the correct day and time is indicated opposite
the datum mark.
2. Automatic Operation
Set the time switch to the symbol. Select the days and
times you require the heater to come on by pulling out the
appropriate segments. Each segment represents a 13/4hour
period for the day indicated. The timer may be set to give as
many ‘ON’ periods of any length required in multiples of 13/4
hours. The programme will repeat itself every 7 days until
changed.
The programme may be over-ridden at any time by switching
to or and can be reinstated by switching back to
setting.

Safety - Overheat protection
For your safety this appliance is fitted with a thermal cut-out.
In the event that the product overheats for some reason, the
cut-out prevents excessive temperatures on the product by
cutting the power to the heater. Once the heater has cooled
down, it will reset automatically, it will continue to cycle on
and off automatically until the reason for overheating is
removed.
Cleaning
Before commencing cleaning, unplug the heater and allow it
to cool. Disconnect the electricity supply to the appliance.
The outside can be cleaned by wiping it over with a soft damp

Energy Saving Tips
The energy we use to heat, light and power our homes
contributes over a quarter of the UK’s carbon emissions, the
principle contributor to climate change.
Around half the energy used in the home is for heating and
hot water, so using your heating system efficiently will not
only help the environment, but also save you money !
Energy efficiency tips for heating and hot water
1. Don’t set the temperature too high…
By reducing the thermostat setting by just 1ºC can reduce
your energy use by as much as 10%. And if you’re going
away for the winter, leave the thermostat on the frost protection
setting to provide protection from freezing at a minimum cost.
2. Use it where you need it…
Set the appropriate temperature on your heaters for the room
they are in; for example, leave the thermostat on a heater in a
spare bedroom on a lower setting.
3. Use it when you need it…
Use heaters fitted with timers or linked to central controllers
to turn the heating on only when you need it and automatically
switch it off when you don’t.
4. Curtains…
Close your curtains at dusk to stop heat escaping through
the windows.
5. Windows…
Nearly 25% of heat loss can occur through poorly insulated
frames and single glazing. If you can’t afford to double glaze
all your windows, go for the rooms you heat most.
6. Treat your hot water tank...give it a jacket
An insulating jacket for hot water tanks only costs a few pounds
and pays for itself within months. Fit one that’s at least 75mm
(3") thick and you could save £10-£15 a year.
7. Water …
Use a shower if you have one to save time, money and water.
Don’t set the thermostat too high on your water heater - 60oC/
140oF is usually adequate for bathing and washing.
Put the plug in when running hot water in your sink - leaving
hot taps running is both wasteful and expensive.
Ensure dripping taps are repaired quickly. In just one day,
you could waste enough water to fill a bath.
Other Energy Saving Tips for Around the Home
1. Lights
Turn off lights whenever you leave a room for more than ten
minutes.
Use low-energy bulbs wherever you can as they use less
than a quarter of the electricity used by ordinary light bulbs
and last ten times longer!
2. Cooking
Use the right size pan for the food and cooker hob.
Keep saucepan lids on - this enables you to turn down the
heat.
Boil water for cooking in a kettle.
