When I came back on Sept. 7, I saw 559 shown up on the monitor. Not sure when the temperature changed.

There is still an intermittant problem with the controller. The dispay reads out 556 and the oven temperature ramps down during the course of a program cycle.

Verified that all configuration and tuning data was programmed into controller. Did 1 short test with 2 ramp/soak cycles( 200 and 350 degrees). The temperature profile data looked normal. Running another test program with ramp to 180 deg. in 1 hour and soak for 65 hours. If all goes well, all programs 1 through 8 will be reloaded and oven released for use.

User will add program #2 and do a 48 hour test at 180 degrees. We are continuing to monitor the temperature with an external data logger. After this test, all programs will be loaded back into the controller. Will leave in yellow until conclusion of the test.
