Manual No. M/02-207-C009

NOTE:

The Temperature Controller will display the last set point temperature value upon

entering the temperature setpoint screen.

If you do not press either of the

keys or the

SET

key within approximately 4-5 sec-

onds, the Temperature Controller will “beep” and revert to its non setpoint mode (the temperature
will again be displaying tenth degree values). Simply press the

SET

key again to re-enter the

temperature setpoint mode.

2) A press of either the

keys will cause the tenths degree digit to stop flashing

and the tenths degree value to begin incrementing (or decrementing) at a one-to-two char-
acter per second rate. When the scrolled tenths value exceeds ten-tenths of a degree (i.e.
one degree) in either direction, the scroll speed will then accelerate, and the ones digit
will then be incremented (or decremented) as required. If the

keys are held

in for an extended time, the scroll speed will again increase to its maximum rate.

3) If the user releases the

key after more than the 4-5 second timeout period,

the display will revert to that of the current Thermo Container temperature with no
change in the setpoint temperature taking place. At this point, a press of the

SET

key will

display the last valid setpoint temperature that existed before the user began to change
the setpoint temperature.

4) If the user releases the

key after less than the 4-5 second timeout period, and

then re-presses an

key, the display will return to the tenths degree digit set

mode and again begin the temperature set mode as described above.

5) If the user scrolls to some new setpoint temperature, releases the

keys and

presses the

SET

key, the Temperature Controller will accept the scrolled-to temperature

as the new setpoint temperature. If the user had pressed the

RUN

STBY

instead of the

SET

key,

the temperature controller would have begun controlling the Thermo Container at the new
scrolled-to setpoint temperature. In this case, the RUN

LED would illuminate and

the HEAT

LED may or may not be lit depending on the temperature in the Thermo

Container.

In any case, the Temperature Controller action will be to regulate to the new setpoint tempera-
ture. The current temperature of the Thermo Container will be displayed on the front panel
digital display with the RUN

LED illuminated. Power will be provided to the Thermo Con-

tainer if the new setpoint temperature is higher; the Thermo Container HEAT

LED will be

illuminated. The Temperature Controller will provide power to reach the indicated set point and
maintain it at that level indefinitely.

NOTE:

The last scrolled-to-temperature (the last setpoint temperature) will be re-

tained in non-volatile memory and will become the default setpoint tempera-

ture the next time the Temperature Controller is powered up.
