Ecodyst manufactures the most technologically suitable temperature controller for your system, which should provide
you with constant faultless control. If you are having trouble with your controller, a smart place to start is by putting
the original factory settings into the setpoint controller (i.e., the meter on the top). If you continue to have issues with
your controller, our Engineering sta will assist you in resolving the issue. An Ecodyst controller’s factory settings are
as follows: 0.1°C resolution, PID control with tuning parameters for a heating mantle, thermocouple type to match the
thermocouple initially put on the controller, and a thermocouple oset entered at the time of original calibration.
1.
Press and hold in both the

and

keys on the front of the temperature meter until the word “tunE” appears in the display,
then release both keys.
2.
Press the

key until “LEVL” appears in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the

key
until “3” appears in the display. Let go of all the keys.
3.
Press the

key until “rSEt” appears in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the

key
until the word “All” appears in the display. Let go of all the keys.
4.
Press and hold in both the

and

keys until the word “inPt” appears in the display, then release both keys.
The value that needs to be entered depends of the type of thermocouple receptacle your controller was shipped with.
Determine the thermocouple type below.
Color of thermocouple receptacle (Fig 1; #7) Value to enter:
Blue (type T) “tc
”
Yellow (type K) “tc
”
Black (type J) “tc
”
First hold in the ‘*’ key, then while holding in the ‘*’ key press the

key until the value from the table above appears in the
display. Let go of all the keys. NOTE: Many of the patterns for this parameter look similar, be careful to select the exact pattern
shown above.
5.
Press the

key once and “unit” will appear in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the

key until the value “o C” appears in the display. Let go of all the keys.
6.
Press the

key once and the word “SP1.d” appears in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key
press the

key until the value “SSd” appears in the display. Let go of all the keys.
7.
Press in both the

and

keys until the temperature appears in the display (the word “PArk” also appears), then release
both keys.
8.
Press and hold in both the

and

keys on the front of the temperature meter until the word “tunE” appears in the display,
then release both keys.
9.
Press the

key once and the word “bAnd” will appear in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key
press the

key until the value “10” appears in the display. Let go of all the keys.
Procedure
Only the setpoint controller should be reset using this approach. None of the High Limit controller’s settings should
be modied.
