Program Example
To heat up at 10 °C per minute to 500 °C; to hold at 500 °C for 1 hour; then to allow to

1. Start with display at home; use arrow keys to alter the setpoint to 500.
2. Press scroll until 'sp.rr' shows; use arrow key to set value to 10 (if you do not want
to limit the ramp rate, ignore this step or set the value to OFF)
3. Press scroll until 'tm.op' shows; use arrow key to set value to opt.1
4. Press scroll until 'dwell' shows; use arrow key to set value to 60
To operate this program
5. Press scroll until 'stat' shows; use arrow key to set value to run

6. Cancel 'End' by pressing page and scroll together.
* note that the timer runs for an extra minute, when tmr has counted down to zero;
allow for this when testing the system with short durations such as 1 or 2 minutes.
