Expressed in degrees, from –199 to 999. Use this
parameter to calibrate oven temperature.
Provides levels of access to the controller:
• 0 = No key lock, full access to controller
• 1 = Prevents changing of all parameters except
setpoint
• 2 = Prevents all parameters from being changed
including the setpoint
• -1 = Set to enter the Set-up parameter setting display.
Only when I & d are OFF. Expressed in percent.
Controller outputs this value when process variable equals
setpoint, but only if I = 0.
Only when CtL is OFF, change CtL to PID)
Expressed in degrees. When CtL = OFF, this value
determines the change in temperature needed to turn
controller output from full OFF to full ON.
*If P is not displayed the Control Mode (CtL) must be first set to PID.
5.4.2.2. Control Instrument Operating Mode Notes
• The controller is factory set to LoC=1 (allowing only the setpoint to be changed). This setting
prevents inadvertent changing of control parameters.
• If necessary to alter control parameters, change the LoC=1 to LoC=0. See Section 5.4.2.1 for
more information.
• When LoC = -1, parameters are displayed in the order shown in the Set-Up Parameters table
(Table 5).
• Note: If unable to change setup parameters:
o Change the LoC = 0
o Press the
until LoC appears again
o Change LoC = -1
o Press the

The minimum setpoint limit of oven. The user cannot
change the setpoint below this lower setpoint limit.
Despatch recommends leaving the SC feature OFF
Direct/Reverse action. This value is set for 0 (reverse

Priority of PV/SP display. This parameter either
displays the PV (process variable) or SP (setpoint).
