Technical information
Portable Chiller UGH024/1103
When powered, the chiller control automatically performs a
bootup routine. When the bootup routine is complete, the dis-
play will alternate between “rst” and the actual to process
temperature. To reset the control on power up, press the up
and down arrow keys simultaneously for 1 second. This will
reset the control and return it to he operating mode it was in
before the power was disconnected, this may have been run-
ning mode. If so and the chiller must be stopped, immediately
press the stop/start button after resetting the control. The
chiller is now ready to accept a setpoint and begin operation.
Setpoint
The Setpoint menu only has one parameter, which is the set-
point. This setpoint temperature is the water temperature that
is required to be supplied by the chiller. The setpoint range of
the chiller is 20°F - 65°F, however the standard settings will
only allow the operator to set as low as 45°F. If a temperature
lower than 45°F is required the low setpoint limit (LtS) and
the low setpoint alarm (SPL) must be adjusted accordingly.
These parameters are discussed in later pages. Additionally, an
industrial Glycol will need added to chilled water solution to
prevent freezing. See Chart in Filling the Chiller, Section 3.
To set the temperature setpoint:
Press the Enter button until “SEt” is dis-
played.
Press Enter again to display value of
Setpoint,
To raise and lower the setpoint tempera-
ture. Each time you press the arrow the temperature
changes one unit. Stop when you reach the tempera-
ture you want. This value is in the units chosen ºF or ºC.
See Changing Units, Section 4.
Press the Enter button, to accept the new set-
point temperature. The display returns to the actual
process temperature. If the Enter button is not
pressed the change in setpoint is not retained and any
changes required must be reentered and confirmed.
