III.a.5) Single step

You can use this function to set a percentage value for a single step in the

operation of valve opening, that is to say the maximum percentage value of
opening   or   closing   that   the   valve   can   move   in   a   single   step   (maximum
movement of the valve in one measurement cycle). 

III.a.6) Minimum opening

Use this function to set the minimum value for valve opening. Below this

value, the valve will not close shut.

III.a.7) Type of valve

You can use this option to select the type of valve: central heating

or floor type. 

III.a.8) Weather program (weekly valve program)

In   order   to   enable   the   weather   function   an   outdoor   sensor   should   be

installed in a place not exposed directly to sunlight or weather conditions. 
 After installing and connecting the sensor the Weather program function must
be enabled in the controller menu. 

For the valve to work properly enter set-point temperatures (downstream

of the valve) for the following four intermediate outside temperatures: 

   TEMP. FOR

 -20

   TEMP. FOR
