• Lo P1 is the pump's Low Pressure discharge alarm
limit.
T 0 T 1 Pump Range: 3 to 100 PSI Default: 4 PSI
T 5 Pump Range: 4 to 105 PSI Default: 4 PSI
P 1 P 2 Pump Range: 3 to 100 PSI Default: 4 PSI
P 3 Pump 60Hz Range: 3 to 46 PSI Default: 4 PSI
P 3 Pump 50Hz Range: 3 to 32 PSI Default: 4 PSI
P 4 Pump 60Hz Range: 3 to 85 PSI Default: 4 PSI
P 4 Pump 50Hz Range: 3 to 60 PSI Default: 4 PSI
P 5 Pump 60Hz Range: 3 to 87 PSI Default: 4 PSI
P 5 Pump 50Hz Range: 3 to 56 PSI Default: 4 PSI
Going below this limit ashes Lo P1 and, if enabled,
sounds the alarm.
• dELAY is the length of time the pump can exceed
the Lo P1 alarm limit. Note This feature is only active
if the chiller is congured to shut down with a pressure
alarm.
Range: 0 to 30 seconds
Default: 10 seconds
Exceeding this limit ashes Lo P1 and, if enabled,
sounds the alarm. The chiller reaction depends on the
ALr alarm conguration set below.
• ALr is used to congure the chiller's reaction for
exceeding an alarm limit (temperature, pressure and
optional ow). The chiller will either shut down (FLt)
or continue to run (indC). In each conguration, the
controller will display the error code and sound the
audible alarm, if enabled.
Range:
FLt or indC Default: FLt
• FAnSP is used to control the fan speed (air-cooled
2500 only). Auto allows the fan to run under the
conditions listed in Section 3. Selecting Hi allows
the fan to run at high speed all the time. Note Hi is
required for chillers to achieve a ThermoFlex2500 watt
cooling capacity.
Range:
Auto or Hi Default: Auto
• Sound is used to enable/disable the audible alarm.
Range:
on or oFF Default: on

• StArt is used to enable/disable the auto restart
function. When enabled the chiller will automatically
restart after a power failure or power interruption
condition.
Range:
on or oFF Default: oFF
NOTE Consider any possible risks before enabling
this mode of operation.
• CArE is used to set the preventive care cleaning
frequency reminder for the chiller's air and uid
lters, in hours. The time selected is based on your
operating environment, see Section 6.
Range:
off Default: L1
L1 (1000 hours)
L2 (2000 hours)
L3 (3000 hours)
Off disables the reminder. Exceeding this limit
ashes FLtrS, see Section 6.
Note If your chiller is equipped with any of the
Optional Features refer to the next page.
When the display indicates StorE press
to save all changes or press to not save
all changes. The display will return either the process
uid temperature or, if the chiller was off when you
entered the loop, a blank screen.

• HZ is used to identify the incoming frequency for
chiller's with P 3 - P 5 pumps and the capability to run
on either 50 Hz or 60 Hz. The selected frequency
automatically adjusts the rmware's xed high pressure
default setting.
Range:
50 Hz or 60 Hz Default: 60 Hz
• OPt is used to congure the analog in/out mode of
operation. See Appendix C.
• FiLL is used to set the time limit the auto rell has for
lling the reservoir to the normal operating level.
Range: 0 to 900 seconds
Default: 45 seconds ThermoFlex900 - 5000
80 seconds ThermoFlex7500 - 24000
Exceeding the time limit ashes rEFiL and the auto rell
will shut off. The chiller's reaction depends on the alarm
ALr setting, Flt is shut down, indC is continue to run.
Note Setting the time limit to 0 disables the auto rell
option.
See Section 5 for additional information.
• di t is used to set the preventive care cleaning frequency
reminder for the chiller's DI lter cartridge.
Range:
0 to 9999 hours Default: 448 hours
Exceeding the limit ashes di, see Section 6.
• HiFLO is used to set the high ow alarm limit.
T 0 T 1 Range: 0.0 to 10.5 GPM Default: 0.0 GPM
T 5 Pump Range: 0.0 to 15.0 GPM Default: 0.0 GPM
P 1 Pump Range: 0.0 to 10.5 GPM Default: 0.0 GPM
P 2 Pump Range: 0.0 to 10.5 GPM Default: 0.0 GPM
P 3 Pump Range: 0.0 to 30.0 GPM Default: 0.0 GPM
P 4 Pump Range: 0.0 to 30.0 GPM Default: 0.0 GPM
P 5 Pump Range: 0.0 to 30.0 GPM Default: 0.0 GPM
Exceeding a high limit ashes HiFLO and, if enabled,
sounds the alarm. The chiller's reaction depends on the
alarm (ALr) setting.
Note This feature is not enabled until the value is
changed to something other than 0.0.
Shaded displays only appear
on chillers equipped with that option.
