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 Heat). Each can be set independently
to provide the optimum level of comfort and controllability.
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 (5 bars). To do this,
hold the + button until the 10 bars are illuminated and continue to
hold for a further 7 seconds. The 10 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 fifth
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 (5 bars) 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 1 bar.
Reduce the COMFORT setting to 1 bar.
High Setting
Follow the instructions for ‘Normal Setting’, but:
Increase the BACKGROUND setting to 7.
Increase the COMFORT setting to 7.
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. In order
to check the setting for the ‘background’ heating (retained heat), you must hold the +
button until the 10 bars are illuminated and continue to hold for a further 7 seconds.
The 10 illuminated bars should now be replaced by a single flashing bar (indicating the
current background heat setting level). This can again be raised or lowered using the +
and - buttons. To set these levels to your desired requirements, please follow the in-
structions below.
