Optimum start control (OSC)
Your thermostat includes an optional optimum start control. This
feature allows you to set the time at which you require a room
temperature by. The thermostat then calculates how soon before the
event time the system must be turned up to ensure that the room is at
the temperature by the required time. A full description of this and how
to enable it and set it up is given in User Advanced Programming,
steps 12 & 13, (page 12 and 13).
Battery replacement (battery models only)

appear on the display. You have 15 days to replace

replacing batteries ensure that only high quality
alkaline cells are use.
IMPORTANT: After replacing the batteries press and release the RESET
button to restart the unit. All date, time, programming and override
