IV.1
°F
°C
The °F/°C key
This key is used to toggle the units in which temperatures are displayed and entered. The right
most digit in the main display indicates the units currently being used (F = Fahrenheit; C = Centi-
grade).
IV.2
RUN
STBY
The Run/Stby Key
The RUN/STBY key initiates or stops operation of the Programmable Temperature Controller. To
initiate a temperature program or single setpoint operation, press RUN/STBY. The LED labeled
RUN will light up to indicate the present status of the controller. When the Temperature Controller is
operating, pressing the RUN/STBY key will place the unit in a standby mode and cease control of
the Thermo Container.
IV.3
SET
The Set Key
The SET key is pressed when the operator wants to view or edit temperature and time data. In single
setpoint (non-program) mode, the SET key accesses the temperature setpoint. In programmed mode,
the SET key is used to cycle through the time/temperature program and to accept various options
when the user is “building” a temperature/time program.
IV.4
PGM
The Program Key
The PGM key is pressed when the operator wants to establish, review or use a temperature/time
program. The LED labeled PROGRAM is illuminated when the Programmable Temperature Con-
troller is in the program mode.
IV.5 The Arrow (direction) Keys
The ARROW keys are used to increment (or decrement) temperature values and to scroll through
sub-program options where required. When used to input temperatures, a single press of either of
these keys will result in a single digit increment in the displayed temperature value. When large
temperature steps are required, the user will find it simpler to press and hold these keys. At first, this
will result in a slow increment (or decrement) of the display temperature. However, after a couple of
seconds, the display will rapidly increment (or decrement) and the user must be careful not to over-
shoot (or undershoot) the desired input value.
These keys will not work when the Programmable Temperature Controller is in the run mode.
IV.6 HEAT The Heat LED
The HEAT LED is illuminated when the controller is providing power to the Thermo Container. The
LED will flash at a rapid rate when the temperature of the Thermo Container is being maintained at
a programmed temperature.
