RUNBACK MODE
The towel rail comes with a Runback mode for
use when the heater will be installed in areas
where restricted user control is required.
When Runback Mode is active it allows the user
to set the towel rail to run for a specic pre-set
amount of time and temperature. It is also possible
to set a maximum temperature (Max Temp) above
the Runback setting to allow the user to increase
the temperature within the limits allowed.
Before activating Runback mode it is strongly
recommended that an alternative password is set
and activated and the comfort mode temperature
set-point is set to 35°C. When the password is
activated the user will have no access to any
towel rail settings without the password.
NOTE: Any display settings will be used in
RUNBACK mode, eg. Backlight time and intensity,
Eco mode etc. These should be adjusted prior to
setting Runback to Active.
After the Runback time period ends the room
temperature will return to o󰀨 (7°C minimum) until
the Runback is restarted.
It is also possible to set a minimum temperature
to be maintained (Setback) outside of the Runback
mode; when setback mode is activated the room
temperature will only fall as low as the Setback
temperature. The temperature will be maintained
at this point until Runback is restarted.
ACTIVATING RUNBACK MODE
Runback mode is activated
from the Advanced settings
menu.
The main Runback screen
has 3 options:
• Runback Cong
• Setback Cong
• Max Temp
Set Runback to ON to
activate the mode.
Note: The Runback settings menu is not
available unless the Runback mode has been
turned on.

The time can be limited to any of the above
values, when the user activates the Runback
timer, they can choose any of the times up to the
maximum set on installation. After the Runback
has expired the next activation will start at the
previous time selected. i.e. If the previous setting
was 60min, the next activation will start at 60min.
The temperature that
the towel rail runs at when
Runback is activated is
set in the Runback Temp
menu. Use +/- to set the
temperature and press
Mode/OK to conrm.
Please note that the
Runback temperature
cannot be set higher than
the Comfort setting in the
main menu.
SETBACK
The setback mode can be
used to limit the temperature
that the area where the heater
is installed can fall to outside
of the Runback operation.
This temperature can be
set between 7°C (minimum)
and 0.5°C less than the
Runback temperature set-
point.
When Setback is
operational, the screen will
show “Setback” and the set-
point.
MAX TEMPERATURE
The Max Temperature
setting allows the installer
to set a temperature
higher than the Runback
temperature set-point to give
the user some leeway in the
temperature of the room.
Typically this is set 1-2°C
higher than the Runback
setting.
Both the Setback and
Max temp are set with the +/- buttons from their
respective menus, using Mode/OK button to enter
the desired mode.
The graphs below show typical scenarios for
each of the settings.
When Setback and Max temp is OFF, the user
has a choice between the minimum towel rail
temperature of 7°C and the Runback temp setting.
Outside of the Runback period the temperature
will fall as low as 7°C if the towel rail is not re-
activated.
When Runback and Setback are activated then
the user has a limited choice of temperature
between the Setback setting and the Runback
setting.

TROUBLESHOOTING
If the power of the Lithium
battery drops, in the screen,
a small icon will remind the
user that the battery is at.
When a towel rail has been
paired with a Gateway, the
text “Link” and an antenna
with ashing waves appears
on the top right of the screen.
If the towel rail is paired with an internet
connected Gateway the time and date are always
updated when the towel rail reconnects to the
Gateway.
When the Gateway is not
powered or it is too far away
from towel rail, the Link
text alternates with a red
antenna without waves to
alert the user that the towel
rail cannot communicate
with the Gateway.
If a towel rail is paired with a Gateway, and the
internet connection is lost the heating system is
not accessible from the app.
However the running schedule remains in the
towel rail memory and continues with the last user
setting so long as the lithium battery is not at.
The Lithium battery (CR2032) life is around 5
years from date of manufacture, this life can be
decreased depending storage conditions.
To change the battery contact your installer or
an electrician.
Outside of the Runback period the temperature
will fall to the Setback temperature if the towel rail
is not re-activated. (Building Fabric Protection)
When all 3 settings are activated then the user
has a choice between Setback as a minimum and
the Max temp setting as a maximum.
The Towel rail will always come on at the
Runback set point.
In the example above the user has activated
Runback and then increased the temperature to
the Max Temp set point after a time.
ERROR CODES
The Towel rail continuously checks to ensure
that it is working correctly all the time, however
in some cases the towel rail may display an Error
code on the screen.
Below you will nd each code and a short
description on the cause of each issue.
OC Disconnected or Open circuit temperature
sensor.
SC Damaged or Short circuit temperature
sensor.
