Cond Fan Speed is a status only item that displays the current
VFD speed when the evaporative condenser option includes a
VFD to control the first condenser fan on each circuit.
Cond Fan Spd Cmd is a status only item that indicates the
current condenser fan VFD commanded speed .
Min Fan Speed is an adjustable item used to set the minimum
speed for the VFD speed when the evaporative condenser
option includes a VFD to control the first condenser fan on
each circuit .
EvCond Stg Tm is an adjustable item used to set a minimum
time period between condenser fan stage changes .
Sump Temp is a status only item that displays the current
evaporative condenser sump temperature .
Min Sump T is an adjustable item used to set a minimum
evaporative condenser sump temperature set point . This value
is used to determine when condenser fans are turned off .
Max Sump T is an adjustable item used to set a maximum
evaporative condenser sump temperature set point . This value
is used to determine when condenser fans should be turned on .
Sump Dump Spt is an adjustable item used to set a minimum
sump temperature . The sump is emptied to prevent freezing if
the sump temperature drops below this set point .
Sump Pump Status is a status only item that displays the
current evaporative condenser sump pump status .

Smp Pmp Delay adjustable item used to set the amount of
time the sump pump fail alarm is delayed . If the Sump Pump
status remains Off after the Sump Pump Output has been
turned on for more than the Sump Pump Delay time, a Sump
Pump fail alarm is initiated .
Conductivity is a status only item that displays the
conductivity level of the water in the sump of an evaporative
cooled condenser on rooftop units .
Hi Cndtvy Spt is an adjustable item that sets the alarm value
setpoint used to generate a conductivity problem alarm
SmpWtrLvlDly is an adjustable item that sets the amount of
time sump water level input is ignored once the unit enters the
cooling state
PostClgTime is an adjustable item that sets the amount of
time the sump pump output remains on after the unit leaves
the cooling state .
SepFlshTime is an adjustable item that sets the amount of
time the Purge Valve Binary Output is turned on to flush the
solids out of the system separator .
Dolphin System is an adjustable parameter that indicates to
the controller whether or not a Dolphin water treatment method
is being used . When set to "yes" the controller assures the
sump pump is run every three days to reduce scaling .
