S213 SUP Sensor Alarms/Init Delay—The parameter to the left enables or disables the supply
sensor alarms. If the unit is not equipped with a supply temperature sensor, then this parameter will
show Disabled. The parameter to the right sets the alarm activation delay for when a supply alarm
will become active after either the high or low threshold has been exceeded.
S214 High/Low Supply Temperature—Sets the high and low supply temperature threshold that
will trigger a High/Low Supply Temperature alarm.
S215 Dew Point Alarms/ Init Delay—The parameter to the left enables or disables the return air
dew point alarms. Dew point alarms can be enabled with any humidity control type. Dew point
alarms may be used with or without humidification and dehumidification options selected. The
parameter to the right sets the alarm activation delay for when a dew point alarm will become active
after either the high or low threshold has been exceeded.
S216 High/Low Dew Point—Sets the high and low dew point threshold that will trigger a
High/Low Dew Point alarm.
S217 Dew Point A Alarms/Init Delay—The parameter to the left enables or disables the optional
Sensor A dew point alarms. Dew point alarms can be enabled with any humidity control type. Dew
point alarms may be used with or without humidification and dehumidification options selected. The
parameter to the right sets the alarm activation delay for when a dew point alarm will become active
after either the high or low threshold has been exceeded.
S218 High/Low Dew Point Sensor A—Sets the high and low dew point alarm thresholds for
Sensor A.
S219 REM Sensor Alarms/ Init Delay—Three selectable options are available for the parameter
displayed on the left: Disabled, Com Set and Sep Set. Disabled prevents remote temperature
sensor alarms from occurring. Com Set or common setting, allows remote alarm activation based on a
common alarm setting located on line S220. Sep Set, or Separate Setting, allows the user to program
unique temperature alarm settings. These setting are located in the User Menu> Set Alarms, page 3.
The parameter to the far right (Init Delay) is the alarm activation delay for both Com Set and Sep Set.
The default setting is 180 seconds with an adjustable range of 0-9999 seconds.
S220 High/Low Remote Temperature—The high and low temperature limits can be set here when
the remote sensors all share common high and low temperature thresholds.
S221 Separate thresholds: User/Set Alarms—Read-only informational parameter that is hidden
when S219 Rem Sensor Alarms are set for Com Set. When S219 is programmed for Sep Set, the S221
is visible. This indicates separate remote sensor alarm thresholds may be set in User Menus> Set
Alarms, page 3
S222 EEV Alarmboard—Sets the EEV Alarmboard events sent to the board as a normally open or
normally closed set of contacts. This parameter is selectable in NO or NC. The default is NC.
S22A Operation on Sensor Failure—Sets the operating characteristic when a sensor fails. Options
for this parameter are Full Cooling and Shut Down. The default is Full Cooling.
