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.
The temperature that the
radiator runs at when runback is
activated is set in the Runback
Temp menu. Use + & - to Set the
temperature and Press OK.
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 and 0.5°C less than the
Runback temperature.
When Setback
is operational,
the screen will
show setback
and the setpoint.
MAX TEMPERATURE
The Max Temperature mode
allows the installer to set a
temperature higher than the
Runback temperature 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.
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 radiator
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 radiator 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.
Outside of the Runback period the temperature
will fall to the Setback temperature if the radiator
is not re-activated. (Building Fabric Protection)
