Over Set Point

The Over Set Point LED will be illuminated if the To Process tem-
perature exceeds the Set Point temperature by more than 5°F
(3°C).  This fault causes only an alarm indication (horn and/or
remote contact) and the unit will continue to operate.  Although
the Over Set Point LED will turn on immediately whenever the
temperature is out of range, the alarm relay is disabled for 30
minutes after start-up or after a change in set point.  The alarm
will automatically clear when the To Process temperature is no
more that 5°F (3°C) above the Set Point temperature.

Under Set Point

The Under Set Point LED will be illuminated if the To Process
temperature drops below the Set Point temperature by more
than 5°F (3°C).  This fault causes only an alarm indication (horn
and/or remote contact) and the unit will continue to operate.
Although the Under Set Point LED will turn on immediately
whenever the temperature is out range, the alarm relay is dis-
abled for 30 minutes after start-up or after a change in set point.
Pressing the Alarm Reset button will reset this fault. 

Pump On

The Pump On LED will be illuminated whenever the pump is
running.  If the pump is shut off due to a safety, the Pump On
LED will turn off.  The Start button must be pressed in order to
restart the pump. 

Heat

The Heat LED will be illuminated when the microprocessor
determines that heating is required. For those units with heaters,
the Heat LED will be illuminated while the heater is energized.
For units without heaters, the Heat LED illuminates depending
on unit set point parameters.

Cool

The Cool LED will be illuminated when the microprocessor
determines that cooling is required. The Cool LED will be illumi-
nated while the cooling solenoid or modulating valve coil is
energized, or when the compressed air purge option is used
during the Auto Vent sequence. 

Vent

The Vent LED will be illuminated while the microprocessor is
performing an Auto Vent sequence. This sequence is performed
each time the Start button is pressed to energize the unit unless
the temperature is above 150°F. The Auto Vent sequence opens
the cooling solenoid or modulating valve for 30 seconds to vent
air from the mold circuit. Then the valve is kept open and the
pump is energized for an additional 30 seconds. The Vent LED

will also be on when the optional compressed air purge is used. 

Probe Fault

The Probe Fault LED will illuminate if the signal from the thermo-
couple is out of tolerance.  This fault will also shut off the com-
pressor and the pump.  Pressing the Alarm Reset button will

reset this alarm. 

Changing Temperature Display Scale

This unit was shipped to display temperatures in either °F or °C.
The following step can be followed to determine what tempera-
ture scale is in use and will provide instructions as to how to

change from one scale to another.

1.  Disconnect main power.

2.  Open the control panel and switch DIP switch #3 to the on 

position and close control panel.

3.  Reconnect main power.

4. With the power connected and the control power off, hold

down the Stop button. While holding the Stop button down,
press the Power button. When the controller illuminates,
release both buttons.

5. The To Process display will read "Unt".  The Set Point display

will show either "F" or "C" depending on the current display
units selected.  If "F" is displayed the temperature display is
in  °F mode.  If "C" is displayed the temperature display is in
°C mode.

6. To change from °F to °C press the Lower Set Point

Temperature button.  To change from °C to °F press the
Raise Set Point Temperature button.

7. The Set Point display now indicates the desired display

units.

8. Press and release the Start button to store the new selection

into the controller memory.

9. Press and release the Power button once to exit the func-

tion.  Press and release the Power button again to restore
controller power.

10.  Disconnect main power.
