Holiday Mode

Holiday mode can be used to keep the system running at lower flow temperatures
and thus reduced power usage whilst the property is unoccupied. Holiday mode
can run either flow temp, room temp, heating, compensation curve heating and
DHW all at reduced flow temperatures to save energy if the occupier is absent.

hold down button E for too long as this will turn off the controller and system.

and select the duration that you would like holiday mode to run for.

mode to activate or deactivate holiday mode for space heating.
