These settings refer to the mode of operation of the system and must be made on
initial start-up. Press - / + together for at least one second:
the message C.O.S.t. will be displayed.
Press than repeatly ALARM until interested variable's message is displayed (see
table below) : variable value and related message will be displayed.
Press + or - to set a new value and then ALARM to confirm.
The next system constant will then appear.
You can press ALARM for a least two second to escape and return to the Run Mode.
*3) You can correct the readings on the sensor (+ or -).
*2) tEnP =1 ; °C Temperature range.
*1) For more details see Operative Diagrams.

Some special condition can cause following messages:
* In these cases alarm output relay is on.
SPECIAL MESSAGGES ON DISPLAY
* When selected probe has
an open circuit wire failure.
*When selected probe has
a short circuit wire failure.
In some start-up conditions may be useful to work in "hand" mode.
Power off theprocessor, press + key and keep it pressed giving power on:
HAnd message will be displayed (release now + key).
Push + until is displayed number required to be handed:
1 = HEAT relay, 2 = Alarm relay.
Pushing again + for increase relay number previous relay is disactivated.
You can press ALARM for a least two seconds to escape and return to the Run Mode.
HAND MODE
At delivery this processor is ready programmed with the following (variable)
settings. To return to these settings at any time:
Power off the processor, press ALARM key and keep it pressed giving power on:
boot message will be displayed (release now ALARM key).
