ASH7 < Superheat < ASH7 – ASH8  Status.
Dove SH = valore di SH
19.4.3 Special conditions
a. With ASH9 = nP: none probe set as SH probe and one relays set as HGi (valve for hot
gas injection) the configuration error is displayed “no Probe For SH”, and the relay set
as HGi is never activated..
b. If the probe used to calculate the SH is in error the related probe fault alarm is
generated (P3 or P4) and the HGi relay is not activated.
20. Alarm list
Usually alarm conditions are signaled by means of:
1. Activation of alarm output 0-12V
2. Buzzer activation
3. Message on proper display
4. Log of alarm: code and duration.
