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 -10
TEMP. FOR 0
TEMP. FOR 10
Heating curve - curve which is used to determine the set-point temperature of the controller
based on the outside temperature. In our controller this curve is established based on four
temperature set-points selected for their respective outside temperatures. Set-point
temperatures must be provided for the following outside temperatures: -20ºC, -10ºC, 0ºC and
10ºC.
