or Reverse acting.
The controller can be configured to shut the
following down during an active Water Alarm:

operation
Allows setting a maximum pump down time
during a loss of flow condition to prevent causing
a high-pressure alarm due to pump down with no
water/glycol flow to the condenser; hidden
unless pump down is enabled; applies only to
water/glycol cooled systems
Sets the threshold for call for cooling (CFC) loss
of flow.
Enables or disables the supply sensor alarms. If
the unit is not equipped with a supply
temperature sensor, then this parameter will
show Disabled. A user may also select the time
delay before the alarm will become active.

threshold that the alarms will be triggered at.
Enables or disables the Return Air Dew Point
alarm. Dew Point alarms can be enabled with
