1. Process LO is a fixed value and will not change if the SP temperature
value is changed. It activates the alarm when the PV temperature drops
below the alarm temperature. Refer to Figure 18. 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
temperature must first rise above the alarm setpoint before the low alarm
is enabled. This allows for normal system startup without activating the
alarm.
