Basic Operation
6 MC19-1.20
3 Quick Start Guide
3.1 Operation as a simple controller
When switched on the controller goes through a short test routine and then shows the
measured temperature. Below it is shown the setpoint temperature (SP) and percentage of
power output.
3.2 Changing the Setpoint
Press up
 down  to select the required SP. If the SP is higher than the measured
temperature, the OP1 indicator will illuminate at the top of the display, indicating that the
controller is calling for power (giving an output).
The controller will immediately attempt to reach the set temperature and maintain it.
3.3 Resetting the programmer
To reset the programmer to simple controller mode, press RUN/HOLD for 2 seconds.
3.4 Operating the current program

To avoid unwanted heating at the end of a program, set the SP temperature to zero
before running a program.

Ensure the programmer is reset to simple controller mode before starting a program,
by pressing RUN/HOLD for 2 seconds.

To start the program, press RUN/HOLD twice , RUN will light up on the display.
The displayed Program Setpoint (PSP) follows ramps, dwells and steps as the program
runs. The SP temperature of the controller does not apply when a program is running.

To pause the program, press RUN/HOLD.

To stop the program and return to simple controlling (reset), press RUN/HOLD for 2
seconds.
When the program ends, the programmer will either:

Automatically reset to operation as a simple controller.

Dwell at the last temperature of the program (with the RUN indicator flashing), until
the operator presses RUN/HOLD for 2 seconds to manually reset, or presses
RUN/HOLD once to restart the program.

Turn power to the elements down to zero.
3.5 Understanding User Levels
There are two levels in the controller; Level 1(Operator) and Level 2 (Supervisor).
Level 1 (Operator) is for the day-to-day operation of the controller and parameters are not
protected by a security code. There are 3 pages at this level. Page 1, Customer Identity,
can only be altered in level 2. Page 2 shows the current program status. Page 3 is for
writing and viewing programs.
Level 2 (Supervisor) provides access to additional parameters and access to these is
protected by a security code. A further 4 pages are accessible in this level as follows;
Customer identity, Control Output Hi percentage, Units.
To Enter Level 2:
1. Press and hold page
 for 3 seconds. The display will show “Access Goto Level 1”
