Operation
Display
The values will be shown with three digits, and with a setting you
can determine whether the temperature are to be shown in °C or
in °F.
Light-emitting diodes (LED) on front panel
There are LED's on the front panel which will light up when the
belonging relay is activated.
The three lowermost LED's will flash, if there is an error in the
regulation.
In this situation you can upload the error code on the display and
cancel the alarm by giving the uppermost button a brief push.
The controller can give the following messages:
E1 Errors in the controller
E6 Change battery in timer. Set the timer.
E7 Error message Cut-out Sair
E8 Shortcircuited Sair
E12 Analog input signal is outside the range
A1 High-temperature alarm
A2 Low-temperature alarm
Alarm message
A43 Check supply voltage for the step engine
A44 Battery alarm (no voltage or too low voltage)
The buttons
When you want to change a setting, the two buttons will give you
a higher or lower value depending on the button you are push-
ing. But before you change the value, you must have access to the
menu. You obtain this by pushing the upper button for a couple
of seconds - you will then enter the column with parameter codes.
Find the parameter code you want to change and push the two
buttons simultaneously. When you have changed the value, save
the new value by once more pushing the two buttons simultane-
ously.

Gives access to changes
Saves a change
Examples of operations
Set reference temperature
1. Push the two buttons simultaneously
2. Push one of the buttons and select the new value
3. Push both buttons again to conclude the setting
Set one of the other menus
1. Push the upper button until a parameter is shown
2. Push one of the buttons and find the parameter you want to
change
3. Push both buttons simultaneously until the parameter value is
shown
4. Push one of the buttons and select the new value
5. Push both buttons again to conclude the setting

*) This setting will only be possible if a data communication module has been
installed in the controller.
Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you reconnect the supply voltage
