1 10 1 °C / °F S
P9
Temperature Regulation Offset. The temperature below set
point that the oven heating turns off. i.e. If P9 is set to 5 and oven
temperature is set to 180, ovenheating will turn ‘Off’ at 175. This is
intended to allow for thermal over-run in the oven cavity
.
0 10 0 °C / °F S
P10
Oven Temperature Offset. This offset is always added to the raw
temperature measurement, to correct the displayed value. (Value shown
on display is the corrected value).

Program Mode - Pre-Heat Temp Condition. In Program Mode
only. The temperature above ‘Set Temperature’ that the oven will
pre-heat to. (To allow for heat loss during door opening and cold
product loading).

P22
Maximum Open Door Time in Program Ready State. This
is the time allowance for door open when loading oven, to avoid Pre-
Heating state re-activating once the door is closed. Note;- If door has
been open longer than the time set (60) and actual
temperature has dropped below the set temperature for that
program, when the door is closed, the oven will revert to the
preheating mode.
