2.8 Installation of Optional Flow Switch
The purpose of a flow switch is to disengage the condensing units from operation should a loss of
chilled solution occur to the evaporator. This prevents damage to the condensing units due to the lack
of heat transfer through the evaporator and liquid slugging of the compressor.
If a flow switch is used, it should be a normally open switch and installed in the chiller solution
circulation loop.
Remove the jumper between terminals 4 and 5 in the electrical enclosure and wire the flow switch in
series between terminals 4 and 5.

3.3 Temperature Control Lock and Unlock Features
The temperature control is equipped with a locking feature to prevent unauthorized adjustments to the
calibration, temperature setpoints, and unit of measure.
LOCK —To lock the temperature control, press and hold the + ▲+ ▼keys in sequence. The
display will show a series of dashes “- - -.” Continue to hold the three keys (approximately 10 seconds)
until the display changes from a series of dashes “- - -” to the current sensor probe temperature. If the
series of dashes “- - -” are not displayed within 2-3 seconds after initiating this key pad sequence,
release the three keys and repeat the lock process from the beginning (see note below).
UNLOCK —To unlock the temperature control, press and hold the + ▲+ ▼keys in sequence.
The display will show a series of dashes “- - -.” Continue to hold the three keys (approximately 10
seconds) until the display changes from a series of dashes “- - -” to the current sensor probe
temperature. If the series of dashes “- - -” are not displayed within 2-3 seconds after initiating this key
pad sequence, release the three keys and repeat the lock process from the beginning (see note below).
Note: The three keys must be pressed and held in sequence —not simultaneously . The simplest
method to initiate the three key “Lock/Unlock” sequence is by pressing and holding the key with
the left thumb, then the ▲ key with the right thumb while rolling the pad of the right thumb
downward to press and hold the ▼key.
LOCK VALIDATION —To validate that the controller is in the locked position, press and hold the
key until the setpoint temperature is displayed. If the display immediately reverts back to current
sensor probe temperature when the key is released, the controller is locked. If the display shows
the setpoint setting for 5-8 seconds after releasing the key, the controller is not locked.
3.4 Self-Test Procedure
A self-test procedure allows the user to verify that the LED’s in the electronic controller are operating
correctly before the control is put in service.
IMPORTANT: Disconnect all loads (refrigeration and circulation pump motor) before beginning the
self-test procedure!
Conforming to the instructions in the note above, press and hold the ▲key and ▼key in sequence,
holding both keys together for 5 seconds. All LED’s and stage indicators will illuminate in a sequence,
then the display will go blank. Cycle supply power off, then on to resume normal position.
3.5 Temperature Controller Programming
Prior to making any adjustments, the temperature controller must be unlocked as instructed in Section
3.3. After each specific program modification or setting change, the key must be pressed to retain
the new setting valve. Sections 3.6 - 3.11 provide detailed programming instructions.
3.6 Direct Cool Mode
The electronic controller must be programmed for the “Direct Cool Mode” when used with the chiller.

a. Press and hold the and ▼keys simultaneously for 7 seconds (current mode will be displayed).
b. Press the ▲or ▼key until “4d” is displayed.
c. Press the key to save the new mode of operation.
3.7 Setpoint and Differential Operation
The setpoint programmed for Stage 1 (S1) controls the off-cycle temperature for condensing unit
number one, while providing the relative “base line” for which all other setpoints are determined and
calculated. Therefore, Stage (S2), (S3), and (S4) setpoints are calculated and programmed as a positive
offset value above the setpoint value previously programmed for Stage 1 (S1).
The differential is relative to each individual setpoint stage, providing a programmable offset value to
energize each stage on temperature rise. See the example and Figure 2 below.
EXAMPLE—Instant Cooling Application Utilizing Propylene Glycol Solution:
Stage 1: (S1) setpoint “34” (Off at 34°F)
(H1) differential “1” (On at 35°F)
Stage 2: (S2) setpoint “2” (Off at 36°F)
(H2) differential “1” (On at 37°F)
Stage 3: (S3) setpoint “3” (Off at 37°F)
(H3) differential “1” (On at 38°F)
Stage 4: (S4) setpoint “4” (Off at 38°F)
(H4) differential “1” (On at 39°F)
IMPORTANT: Programming for each installation will vary. Setpoints and differentials should be
programmed to eliminate excessive cycling of the condensing units that could cause premature failure
of the refrigeration compressor. Compressors should not cycle more than 5 times in a one-hour period.
