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 (PV = Process Value) in the upper part of the display, and below it,
the set temperature (Set Point).
3.2 Changing the Set Point
Press Up
 or Down 
to select the required SP. If the SP is higher than the measured
temperature, the OP1 indicator will illuminate in the top left corner 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 then maintain it.
3.3 Using the controller
The parameters in the controller are first shown by a short code (mnemonic). After 5
Seconds a description of the parameter will scroll once along the display and then revert
back to the mnemonic. The scrolling text can be interrupted at any time by a single press of
any of the buttons, but will not scroll again until the parameter is returned to. In this manual
the mnemonic will be shown first followed by the scrolling text in brackets;
e.g.
WRK.OP <WORKING OUTPUT>
