Your DuoHeat radiator works by providing continual warmth from a
carefully balanced combination of retained and ‘direct response’
heating.
Some energy is taken in by the radiator when electricity tariffs are
low. The radiator will automatically determine how much heat
needs to be stored each night depending on changing weather
conditions. This stored heat is then gradually released over the
course of the following day.
The stored heat is supplemented whenever needed by top up heat
from the radiant front panel, to ensure room temperatures remain
at your preferred level throughout the day. This supplementary
heat is only utilised when the background heat is no longer suffi-
cient to maintain the desired room temperature.
As such, DuoHeat has two output modes, COMFORT (Radiant heat)
and BACKGROUND (Retained off-peak heat). Each can be set inde-
pendently to provide the optimum level of comfort and controllabil-
ity.
For DuoHeat to operate correctly, both electricity supplies
must be switched on at all times.
Heater Controls - Initial Set Up
Depending on your comfort requirements, there are three
recommended settings:
Low: e.g. holiday home during period of vacancy
Normal: e.g. typical use
High: e.g. sheltered accommodation
Both the Comfort and Background heat settings need to be set
accordingly.
Normal Setting
This is the factory default setting, however you should check this
has not been altered by the installer.
Set the BACKGROUND setting at the mid point (4th red bar). To do
this, hold the + button until all red bars are illuminated and continue
to hold for a further 7 seconds. The illuminated bars should now be
replaced by a single flashing bar (indicating the current background
heat setting level) Adjust this upwards or downwards until the 4th
red bar is illuminated by pressing the + and - buttons. Flashing bar
Low Normal High
After 20 seconds, the display will revert to the standard COMFORT
mode.
Set the COMFORT control at the mid point (4th red bar) by pressing
the + or - buttons to change the number of illuminated bars.
Low Setting
Follow the instructions for ‘Normal Setting’, but:
Reduce the BACKGROUND setting to lowest setting—this will illumi-
nate a single blue bar above the “frost” symbol.
Reduce the COMFORT setting to this single blue bar.
High Setting
Follow the instructions for ‘Normal Setting’, but:
Increase the BACKGROUND setting to 7th red bar.
Increase the COMFORT setting to 7th red bar.
Please note that at high setting the room temperature will be
warmer with a corresponding increase in running costs.
Operate the radiator for 24 hours before making further
adjustments to the settings, as it will take 24 hours for
any changes to fully take effect.
After 24 hours, you may wish to make some minor adjustments to
achieve your optimum comfort level (Please see overleaf)
How does the Control Panel Work?
On the DuoHeat, both output modes - Comfort and Background - are controlled by the
same control panel. The default display illustrates the current ‘Comfort’ (radiant heat)
setting by displaying a certain number of illuminated bars. Each bar relates to a level of
room temperature - the higher the bar, the higher a room temperature the heater will
attempt to maintain. This can be raised or lowered using the + and - buttons. The con-
trol panel consists of 1 blue LED bar (frost protection/low setting) and 9 red LED bars.
In order to check the setting for the ‘background’ heating (retained heat), you must
hold the + button until all red bars are illuminated and continue to hold for a further 7
seconds. The illuminated bars should now be replaced by a single flashing bar
(indicating the current background heat setting level). This can again be raised or low-
ered using the + and - buttons. To set these levels to your desired requirements,
please follow the instructions below.
Blue LED illuminates here when in frost protec-
tion mode/low setting.

Child Lock Feature
Achieving Your Optimum Comfort Level
If the room is not at the desired temperature in the morning, adjust the Background level up or down accordingly. This will ensure that
more (if setting is raised) or less (if setting is lowered) heat is stored overnight for use the following day.
If the room is not at the desired temperature in the afternoon/evening, adjust the Comfort heat level up or down accordingly. This will alter
the amount of supplementary heat provided by the radiant panel as the background heat output diminishes.
When making adjustments to the Background setting, it is recommended that you do not change the setting by more than
one bar at a time.
• To activate the child lock, press and hold the + and - buttons together
for approximately 3 seconds.
• The key symbol on the display will illuminate red, indicating that the con-
trol is locked and cannot be adjusted.
• To deactivate the child lock, press the buttons simultaneously again for 3
seconds, until the key symbol is no longer illuminated.
• If the child lock LED is illuminated green, this indicates that the DuoHeat
radiator is being controlled remotely by a wall mounted programmer.
Once the Background level has been set at a comfortable level (see Achieving Optimum Comfort Level above), this should not require any
further adjustment. The on-board thermostats will work to ensure that the DuoHeat maintains your room at the desired temperature, irre-
spective of external weather conditions.
However, you can adjust the Comfort setting as required to suit your comfort needs and occupancy pattern:
For example, the comfort control can be lowered slightly to save energy when the room is unoccupied, or temporarily increased in order to
provide an immediate boost of heat.
For more comprehensive advice on using your DuoHeat radiator, please refer to the Operating Instructions.
