Option 11 - Start-up method
Your thermostat can start up the system in three
di erent ways. Press + until Option 11 is displayed,
use Λ and V to select required setting.
Setting 0 Normal: Heating is turned up or down at the programmed
times.
Setting 1 Optimum start control (OSC) (or Comfort Setting): This
allows you to programme the time at which you would like
to be up to the required temperature. The thermostat then
calculates how soon before the required time the heating
is turned up. This will vary with weather conditions ranging
from a maximum of 120 minutes to 0 minutes before
the programmed event time. This setting must be used
together with option 12 to match the optimiser setting to
the building in which it is installed.
Setting 2 Delay start (or Economy Setting): This is an alternative to
OSC. Set the event times in the normal way taking into
account the time that the building takes to heat on an
average day. The thermostat monitors switch on time,
actual temperature and wanted temperature and delays
the start of the heating if the actual temperature is close to
the programmed temperature.
