• 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.

• LoFLO is used to set the low ow alarm limit.
T 0 Pump Range: 0.0 to 10.5 GPM Default: 0.0 GPM
T 1 Pump 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
Going below the low limit ashes LoFLO and, if
enabled, sounds the alarm. The chiller's reaction depends
on the alarm (ALr) setting.
This feature is not enabled until the value is changed to
something other than 0.0. If the feature is not enabled
and the ow rate drops below the ow rate listed below
the chiller will continue to run and the controller will ash
between FLo and LoFLo.

• SEr is used to congure the serial communications
mode of operation. See Appendix D.
Note Keypad operation is still available with serial com-
munications enabled.
• drAin is used to open and close the chiller's anti
drainback valve for draining, see Section 5.
Range:
yes or no Default: no
Note The chiller must be off to drain the valve. The valve
automatically closes when you exit the drAin display.
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.

Shut Down
Press the key on the controller.
Note To protect the chiller's compressor, the chiller will enter a 5 to 20
second shut down cycle (colder process uids take longer) before the
refrigeration system and pump shut down. During this time the display
will indicate
OFF
. The bars will scroll downward indicating the
controller is in the shut down cycle.
Using any other means to shut the chiller down can reduce the life of the
compressor.
For ThermoFlex900 - 10000 chillers, when the display goes blank it is safe
to place the circuit protector located on the rear to the off ( 0 ) position.
Always turn the chiller off and disconnect it from its supply voltage
before moving.
For ThermoFlex900 - 10000s, the circuit protector located on the rear
is not intended to act as a disconnecting means.
