Press H to accept the start time.
Enter the End time for switching time 1.

HW Override
Pressing the A button changes the current state of
the HW. For example, if the HW is currently timed
to be off pressing A will turn on the hot water.
TIMER ON will flash to indicate the hot water has
been overridden and it will remain in this state until
the A button is pressed again.
