Setpoint Alarms

Set Temperature
The Setpoint Alarm screen lets you set a high temperature and a low temperature alarm relative to the Set
Point. For example, if your Set Point temperature is 70 degrees, and you want the alarm to trigger 10 degrees
above this value you will enter the 10 as shown above.
Time Value
The Time Value that must be met in order to trigger the alarm. A value of 99 disables the alarm. If the value is
zero, then the alarm will occur immediately when the temp setting is met.
Note: It is highly recommended you use the optional Link4 Sensaphone to call your user preset phone numbers
in case of an alarm being triggered.
Note: If both alarm lights go on, this is an indicator that the temperature sensor for inside temperature has
malfunctioned.
