DESCRIPTION
TECHNICAL SPECIFICATIONS
Put the selector keys in the desired position and press the key for 10 seconds
until appear the indication . Release key and wait until appears the value
programmed for this function, use the key again to modify this value. After adjusted
the new value for the function wait 4 seconds. The controller will record the new
parameter and will pass to the function . Use the same procedure to modify
the value of this function. Repite this for the functions and that will be
the next to be showed in the display to be configured. After the alteration of the
parameters the display comes to the indication of temperature.

Install on power supply.
Sensor cables and computer signals can be together, however not at the same
place where power supply and load drive pass for.
Install suppressor of transient in paralell to loads to increase the usefull life of
