Button Description of Operation
Start
Pressing the Start button initiates a vent sequence. The vent sequence removes air that may have separated out from the water to
prevent improper operation and premature heater failure. When initiated, the vent sequence opens the cooling valve for 30 seconds
to allow air to escape then runs the pump for 30 seconds while the cooling valve is open to remove any remaining air from the sys-
tem. Once the vent sequence is complete, the cooling valve closes, the pump remains running, and normal operation begins. When
the unit is running the Run indicating light is on and green. If the auto start feature is enabled it will have precedence over the start
button. See the Program Menu section for instructions on how to enable or disable the auto start feature. The vent sequence cancel
prevents the vent sequence from occurring when the unit has been operating and the fluid temperature is elevated. The factory
default value for the vent sequence cancel is 120°F {49°C}. See the Program Menu section for instructions on how to change the
vent sequence cancel temperature. The Start button also performs an enter function while in the programming menu.
Stop
Pressing the Stop button clears all faults and stops the pump. With the auto start function enabled and an auto start signal is pres-
ent, pressing the stop button will not stop the unit. The Stop button also performs a cancel function while in the programming menu.
Alarm Reset When an alarm condition is present, the alarm light is on and red. The first Alarm Reset button press will silence the alarm horn
(optional), open the remote alarm contact (optional), and the alarm light changes from red to yellow. The alarm horn (optional) and/
or remote alarm contact (optional) remain disabled until a subsequent alarm occurs. A second press of the Alarm Reset button
resets the state from Alarm to Normal Operation.
Up
The Up button raises the set point temperature. Pressing the Up button and releasing it increases the set point temperature by one
degree. Pressing the Up button and holding it increases the set point temperature until reaching the maximum allowable set point
temperature. In addition to adjusting the set point temperature, the Up button adjusts various alarms and set point values when the
unit in the programming mode.
Down
The Down button decreases the set point temperature. Pressing the Down button and releasing it decreases the set point tem-
perature by one degree. Pressing the Down button and holding it decreases the set point temperature until reaching the minimum
allowable set point temperature. In addition to adjusting the set point temperature, the Down button adjusts various alarms and set
point values when the unit is in the programming mode.
Display/
Pressing the Display/Program button changes the temperature displayed in the Process screen from supply to return. When the
Program display is set to supply temperature, an orange indicating light is on in the lower right corner of the Process temperature display.
When the display is set to return temperature, there is no orange indicating light in the lower right corner of the Process tempera-
ture display. To toggle the Process temperature display from supply to return temperature, press and release the Display/Program
button. The display will return to the default Supply temperature automatically after 5 seconds without a button press. In addition to
switching between the supply and return process temperature displays, the Display/Program button initiates and navigates through
the program menu. See the Program Menu section for more detail.
Mold Purge
The Mold Purge button initiates a mold water purge if this option is present and enabled. The mold purge option allows compressed
(Optional)
air to purge the circuit of water by forcing it out through the cooling valve. To initiate a mold purge sequence stop the unit then
(TW-P Only)
press and release the mold purge button. During a mold purge, the cooling water out valve opens, the mold purge compressed air
solenoid valve opens, and the cooling water inlet valve closes. The mold purge sequence is 1 minute long. To stop the mold purge
sequence before it is completed, press the Mold Purge button again or press the Stop button. See the Program Menu section for
instructions on how to enable or disable this feature.
Rapid Cool
The Rapid Cool button opens the solenoid valve if this option is present and enabled. Pressing the Rapid Cool button initiates a
(Optional)
Rapid Cool sequence. The sequence opens the Rapid Cool valve, opens the vent/cooling valve, and disables the heater. The se-
(TW-P Only)
quence is 1 minute long. To stop the Rapid Cool sequence before it is completed, press the button again, or press the Stop button.
See the Program Menu section for instructions on how to enable or disable this feature.

Process
The Process Cool Down button initiates a cool-down sequence if the process supply water is above 90°F {32°C}. The Process Cool
Cool Down
Down sequence reduces the water temperature before the unit shuts off to extend the life of the pump seal. To initiate a Process
(Optional)
Cool Down sequence, press and release the Process Cool Down button. During this sequence, the cooling valve opens and the
pump runs for 120 seconds or until the temperature of the water reaches 90°F {32°C}, whichever occurs first. During the Process
Cool Down sequence the Set Point display temporarily toggles between the target value 90°F {32°C} and current set point and the
Pump, Cool, and Process Cool Down lights flash green. After the Process Cool Down sequence is complete, the unit stops, the set
point temperature displays in the Set Point display, and the Process Cool Down light remains solid green to indicate the comple-
tion of the sequence. Pressing the Start and/or Stop buttons during a Process Cool Down sequence stops the sequence. See the
Program Menu section for instructions on how to enable or disable this feature.
Note: To initiate a Process Cool Down sequence on a unit with the standard controller press and hold down the Run button, then press the Stop button and then release
both buttons.
