Single Set Point Operation
The automatic control is used as a single set point control,
which includes one ramp to set point capability. To use as a
single set point control, simply push up or down buttons to
choose a specific temperature. The control will cause the
furnace chamber to heat to the chosen temperature and
hold it at this temperature until you turn off the front circuit
breaker switch or select another temperature.
To operate the control:
1. Turn power switch to the “ON” position. The set point
temperature presently set in the control will appear on
the lower display.
2. To change this set point, depress the “UP” or “DOWN”
push button until the desired set point value is displayed
then release the button.
3. The furnace will begin to heat if the new set point
temperature you have chosen is higher than the present
chamber temperature.
4. The upper display indicates actual chamber tempera-
ture.
NOTE
When the program ramp has ended or
has been reset, the furnace will
continue to maintain set point tem-
perature. It will not cool to ambient
temperature unless set point is set to
ambient temperature.
