When switched on, the controller lights up, goes through a short test routine and then
displays the measured temperature or the over-temperature setpoint.
The page key
allows access to parameter lists within the controller.
A single press of the page key
displays the temperature units, normally set to °C;
further presses reveal the lists indicated in the navigation diagram.
The scroll key
allows access to the parameters within a list. Some parameters are
display-only; others may be altered by the operator.
A single press of the scroll key
in the 'Home' list displays the temperature units;
further presses reveal the parameters in the current list indicated in the navigation
diagram.
To return to the 'Home' list at any time, press page
and scroll
together, or wait
for 45 seconds.
The down
and up
keys are used to alter the setpoint or other parameter values.

Altering the Setpoint
With the display at 'Home', showing the measured temperature, press down
or up
once to display the setpoint; press again or hold down to adjust it. The display returns to
