End of Time Period
Modes 1 and 3: heating stops at the end of timing; the
m-A
parameter changes to

m-A
parameter remains at
Auto
.
Mode 5: heating starts at the end of the timing period; the
m-A
parameter remains at

.
In modes 1 to 4 the alarm message
EnD

StAt
parameter remains at
run
.
In mode 5 there is no End message; the

at the end of timing.
