5.  Parameter setting 

5.1. 

Setting the Set Point (SP parameter) 

Adjusting the set temperature is approached directly from the main display by pressing the "UP" or "DOWN" 
button. The upper display is a written message SP, and on the lower display shows the current value of the 
set temperature. Diagram of the set temperature settings is given in Figure 3.

 

 

Figure 3 

Since  the  adjustment  starts,  it  is  possible  to  call  one  of  the  four  previously  stored  values  for  the  SP  by 
successive presses of the button "M". Thus, the selected value is still can be changed (see Figure 4).

5.2. 

Setting other parameters 

When the upper display shows the name of the desired parameter (the lower display shows the parameter 
value), press the "M" button to access its settings. An example of setting the value of parameter "Int" is given 
in Figure 5.

6.  Overview of some important configuration parameters

 

Pressing the "M" button from the basic view starts the overview of some important configuration parameters. 
This allows the user to review the parameters defining the type of measuring probe, type of the output relay 
operation, behavior of relays in case of incorrect temperature measurements etc., without realizing the higher 
level passwords. 

The  upper  display  shows  the  parameter  name  while  the  lower  shows  parameter  value.  Keys  "UP"  and 
"DOWN"  proceed  to  the  next  i.e.  the  previous  parameter.  Return  to  the  basic  view  is  achieved  by  briefly 
pressing the "P", or automatically 10 seconds after releasing the last pressed key.
