Note:
To assist in the setup of your profile, it is recommended that you first record all applicable parameters
above for each segment that you wish to program (either on paper or in a spreadsheet) and then simulate what
the profile should achieve. Once you have established the correct profile parameters, they can then be entered
into the controller and tested.
-
Once you are ready to enter the profile parameters :
-
Press
until
is displayed in the Current Temperature/Parameter Display.
-
Press
or

-
Press
to begin cycling through the profile parameters above.
-
Use

-
Whilst in static mode, press
to select the profile number and segment from which you wish to start
running. For example, to run profile 1 from the beginning, enter “P1.00” which represents profile 1,
segment 0. To start profile 2 from the beginning, enter “P2.00” and so forth. To start from mid-way
through the profile, enter the segment number after the decimal point. For example “P2.03” to start
from segment 3 of profile 2.

Once the profile has ended, press
+
simultaneously to restore the controller to static operating
mode.
