LO Alarm
1. LO Alarm activates the alarm when the PV temperature drops below the
alarm temperature. Refer to Figure 12. If the Control Action is set to
HEAT and the PV temperature is below the alarm temperature when the
RUN Key is pressed, the alarm will not be activated. The PV tempera-
ture must first rise above the alarm temperature before the low alarm is
enabled. This allows for normal system startup without activating the
alarm.
