To set a process time:
Press the
P
key;
t1
shows momentarily on the display and the SET/CNT light flashes quickly.
Use the arrow keys to adjust the process time, which is in hours and minutes (hr.mn). Wait 5
seconds without pressing a key, or press the U key once, and the display returns to normal.
If a process time of zero is set then the timer is disabled and the controller operates as though the
timer is not present.
To start the timer:
Press the
U
key once. Timing starts. The SET/CNT light flashes slowly while timing is in
progress, and the display counts down (at the end of each minute).
At the end of timing the
OUT
light comes on continuously and power to the temperature
controller is cut off.
To reset the timer after timing has finished:
Press the
U
key once. The timer is now idle: it is not stopping the oven from heating, nor is it
timing.
Power is only supplied to the temperature controller when the timer is reset or is timing.
To stop the timer during timing:
A press of
U
during counting down stops the timer. The temperature controller remains on.
It is not possible to resume timing from where it stopped: the next press
U
resets the timer.
