User Interface
Display - The display consists of 3 digits, with the automatic display of the decimal point between -19.9
and + 19.9°C; outside this measurement range, the value is automatically displayed without decimal
(although in its inside the machine is always operating by taking into account the decimal part). During
the normal operation, the displayed value corresponds to the temperature being read by the probe
B1, that is the evaporator water in-let temperature.
Status of the unit - The User is informed of the status of the unit by means of four LEDs on the
display.

Alarms and Signaling
Any time an alarm condition is detected, the controller will prompt the following actions:
xthe buzzer sounds
xthe alarm relay energizes
xthe temperature value blinks on display
xthe alarm code appears on the LCD alternatively with the temperature value
After the alarms have been cleared either with automatic reset or by pressing the and buttons
simultaneously for 5 seconds (for alarms with manual reset), the controller will restore normal operating
conditions:
xthe buzzer turns off
xthe alarm relay disenergizes
xthe temperature value blinks no longer
xthe alarm code disappears from the LCD
If the alarm condition persists, the actions described above will be performed again.
