The CHPRSTATDP comes preset with a default program so that
you can get up and running straight away. Each day is split into 6
parts. Each one can have its time or temperature changed to suit you.
When the DIP switch is set to Optimum Start, the default program
is as the Chart 1 below.Chart 1 shows the target time and target
temperature(i.e.when you require to be warm ).
When The DIP switch is set to Delayed Start, the default program
is as the Chart 2 below.Chart 2 shows the earliest start time and
target temperature. If the temperature of the previous program is
higher, the next program time means the target time. For example ,
the MORN temperature is 21℃, and the Day temperature is 15.5℃.

So the thermostat do not need to turn on the load in advance, it only
needs to keep the temperature as 15.5℃after 8.30am.
