The Coastal MK II is equipped with a buzzer to sound an alarm if the temperature exceeds the set point by the maximum
and minimum values as entered in A1 and A2 in the ALA menu. See
values so that the alarm feature is effectively disarmed. The alarms can be activated by adjusting the values of A1 and/or A2 to the
desired number of degrees above or below the Set Point at which the alarm will operate.
The alarm is set to become operational 3.0 hours after the system is started. This can be adjusted in A6.
The alarm is set to activate 0.5 hours after the threshold set in A1 or A2 is reached. This can be adjusted in A7.
An alarm can be silenced by pressing the Set and DOWN buttons together.
