7.2. Setting the work set point:
Press the SET button: on the red display the current value flashes and Set1 appears on the yellow display; press
the up/down buttons to change the current value. Press SET again or wait 10 seconds to save the new value.
7.3 Programming the parameters
To enter the programming mode press for 5 seconds. The first parameter is reached, whose label is
shown on the yellow display and value on the red display.
To change a parameter, use the up/down buttons to reach the parameter desired. Press the SET button, the
current value flashes, use the up/down buttons to set the new value. Then press SET again to go to the following
parameter. Wait 10 seconds to leave the programming mode automatically.
