Changes to Building regulaons.
Please note that the informaon
is given guidance only.
As of 1 January 2005, changes to
the Building Regulaons aected
domesc electrical installaons
in England and Wales. You do not
need to be a qualied electrician
to make changes to your home’s
electrical system, but the work
must be done in accordance
with the standards in the Reg-
ulaons. In order to make sure
that you comply with the latest
regulaons regarding electrical
work carried out in a dwelling go
to www.planningportal.gov.uk
1. The electric installaon to which
the heater is connected should
have a current dierenal relay
(R.C.D.) of 30 mA and the right
overcurrent relay. With the per-
manent installaon (cable con-
necon without plug) it is also
mandatory to have an omni-pole
cut-out for disconnecting the
device on all poles, by points of
contact with the clearance of
3 mm.
2. All of our heang elements are
factory tested and in full working
order when they are despatched.
Although not advisable, should
you be required to test the heat-
ing element prior to full instal-
laon make sure that the test is
carried out in the open air and
that the heang element is only

3
on for a maximum of 3 seconds.
BEWARE! DURING THIS TEST THE
HEATING ELEMENT WILL GET
VERY HOT ALMOST IMMEDI�
ATELY; ONLY HOLD THE UNIT
BY THE BASE, DO NOT TOUCH
THE ELEMENT AND DO NOT PUT
DOWN UNTIL COOL ENOUGH TO
DO SO.
3. The device is suitable for con-
necon in zone 3, as dened by
applicable regulations, unless
otherwise specied by regula-
ons applicable in the country
of installaon and use. Aen-
tion: the device must be in-
stalled out of reach of persons
in the bathtub, shower or pool.
Zone 1
Zone 2
Zone 3
4. ELECTRIC RADIATOR ONLY - Your
radiator should be filled with
a carefully measured amount
of liquid. In the case of loss of
heang liquid, or in any other
case which demands its replace-
ment, contact your supplier.
5. The device is not equipped with
an external temperature con-
troller. Do not use the device in
a small room if unsupervised dis-
abled or incapacitated individu-
als are inside it. Only use the de-
vice if those individuals are under
constant supervision.
6. If the device is used as a clothes and towel dryer,
ensure that the fabrics drying on it have only been
washed in water, avoiding contact with any harsh
chemicals.
7. Connect the unit to a sound electrical installaon
(see the rangs on the heater).
8. All installaons to which the device is connected
should comply with regulaons applicable in the
country of installaon and use. Extension leads or
electric plug adapters should not be used in order to
supply power to the heater.
9. Ensure that the heater has been installed on a wall
in accordance with its installaon manual.
10. Before installing or removing the device, make sure
it is disconnected from the power source.
11. Please forward this instruction manual to the

Notes for safe use.
1. The heating element’s power
output must not exceed the ra-
diators power output for the pa-
rameters 75/65/20° C.
2. The pressure in the radiator-
should not exceed 10 bar. En-
sure that an air cushion is pre-
served in electric radiators.
3. When heang a radiator as part
of a dual fuel heating system
always leave the ow and re-
turn valves open on the radia-
tor that it is ed to in order to
prevent pressure build up due
to the thermal expansion of the
liquid.
4. Do not turn the heang element
on in an empty radiator!
5. The heang element must be fully submerged in the
heang liquid during its operaon.
6. Ensure that the power cord does not touch the hot
parts of the heang element or radiator.
7. The device is intended for home use only and is
recommended for use solely as described in the
manual.
8. Regularly check the device for damage to ensure it is
safe to use.
9. If the power cord is damaged the device should not
be used. Disconnect the device from the supplying
net and contact the manufacturer or distributor.
10. Do not allow flooding into the heating element
casing.
11. Do not use the heang element in heang systems
where the water temperature exceeds 82° C.
12. The heang element and radiator can heat up to
high temperatures. Please be cauous — avoid di-
rect contact with the hot parts of the equipment.
13. Do not open the device — any interference with in-
ternal components will invalidate the warranty.
14. Ensure that minors aged 8 and above or those with
a physical or mental disability are supervised if oper-
ang the device.
15. The device must be disconnected from the mains
during cleaning and maintenance.
16. Cleaning of the equipment by children under
8 years of age is only permied under appropriate
supervision.

ONE
Funcons and use
The ‘ONE’ heang element has two radia-
tor temperature sengs (45° C and 60° C) as
well as an automac 2 hour mer that will
switch o the element.
The on/o buon is also used to change set-
ngs which are idened by using dierent
colours of the LED diode.
The device has a built-in infrared receiver
(IR) for communicaon with a TERMA exter-
nal controller such as DTIR and TTIR, both
of which will provide addional funcons
to the element.

An-freeze funcon
When the heang agent’s temperature in-
side the radiator drops below 6° C, the de-
vice will switch on automacally. This is indi-
cated by a LED diode ashing rapidly every
4 seconds.

9
On/o buon
Turning the device on will result in the radiator heang
up to the set temperature (45/60° C).
After reaching the set temperature the device will
turn o and on regularly in order to maintain the set
temperature.
Changing the sengs of heang
element
Pressing the on/off button will change the setting,
pressing once to turn it in, again to change the tem-
perature and again to turn it o.
1. Turning on – heater is automacally set to 45° C -
yellow light;
2. Increasing temperature to 60° C – red light;
3. Turning o - diode is not on.
The previous sengs are always remembered if the
electricity is cut-o.
Automac switch-o (mer)
Press and hold the on/o buon — the heater starts
working for 2 hours on setting 60° C, after which
it switches o. Acve TIMER is indicated by pulsang
diode.
Regardless of current heating element setting,
the TIMER can be acvated by pressing and holding
the on/o buon.
Quick pressing of the buon will turn o the heang
element.
Remote control mode (Infrared
communicaon)
The ‘ONE’ is pre congured to work with Terma IR con-
trollers (DTIR and TTIR).
If there is a dedicated IR controller inside the room
which sends signals to the heating element, then,
the rst signal correctly received by the heang ele-
ment, automacally switches the device into receiv-
ing mode.
Remote mode is indicated by the diode shining with
constant blue light.
When in this mode, the heater will heat with the heat
output controlled by the external IR controller while
sll regulang the temperature not to exceed approx-
imately 60° C.
Every correctly received signal from the external IR
controller is indicated by short flash of the diode.
If there is a break in communicaon (the heater does
not receive a signal from the external controller for
30 minutes), the heater will switch to a signal await-
ing mode. The blue diode will start pulsang steadi-
ly and the heater will automacally turn o with the
antifreeze function still active until the connection
is reached again.
The TIMER funcon in the ‘ONE’ can also be used in
‘remote mode’ (in such a case, aer the mer opera-
on has seized, the heater will not turn o but it will
return to the remote control operaon).

Notes prior to removal:
1. Before dismantling permanently, disconnect the heat-
ing element from the mains and ensure that the radiator
is not hot.
2. Be aware. A radiator lled with liquid can be very heavy.
When moving the radiator, ensure that you take the nec-
essary safety precauons.
3. Before disassembly, close the appropriate valves and
drain the radiator completely to avoid causing any
damage.
