Description
Sets the temperature threshold when Sensor A High/Low
Humidity alarm will occur
When set for 'Yes', a "Warning" event-type will activate the
Alarm Relay in addition to an "Alarm" event-type.
The Warning Relay (WA Relay) can be activated for different
purposes; during a Call of Dehumidification, during a 'Warning'
event- type, when unit is on Emergency Power and a Customer
Input Alarm is configured for 'Emergency Pwr', during Free
cooling, or during Freecooling (FC) Start.
Determines whether the K11 (WA Relay) is Direct or Reverse
acting.
The controller can be configured to shut the following down
during an active 'Water Alarm':
•
Shutdown the entire unit
•
Shutdown Humidification 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 ' D isabled' . A user may also select the time delay before
the alarm will become active.
Sets the high & low supply temperature threshold that the
alarms will be triggered at.
Enables or disables the Return Air Dew Point alarm. Dew Point
alarms can be enabled with any humidity control type. Dew
point alarms may be used with or without humidification or
dehumidification options selected. A user may adjust the time
delay before the alarm is activated.
Sets the high/low depoint threshold.
