A normal programme might be to start the day with
a start order and precede it with a stop order, as in
the standard programme. However, if necessary,
a series of stop and start orders may be assigned,
and the day may be started with a stop order.
The boiler will not change its operation in the
programming until it encounters an order which
cancels the previous one.
