temperature is given by the ALL or ALU values. rE = temperature alarms are referred
to the set point. Temperature alarm is enabled when the temperature exceeds the

 If ALC=rE: [0.0 to 50.0°C or 0 to 90°F]
when this temperature is reached, the alarm is enabled after the ALd delay time.
ALL Minimum temperature alarm:
 If ALC=Ab: [-100°C to ALU; -148°F to ALU]

restarts after AC time at minimum.

SAF=0 this function is disabled.
tbA Alarm relay deactivation (with oAx =ALr): (n; Y) n = silencing disabled: alarm relay
stays on till alarm condition lasts. Y = silencing enabled: alarm relay is switched OFF by
pressing a key during an alarm.
