ST-707 Rotations Control
5. Minimum opening
In this function, the minimum value of the valve opening is set.
Below this value, the mixing valve will not close any further.
6. Valve type
With the use of this option, the user selects the type of the valve:
CH or floor.
7. Weather-based control
To activate the weather function, external sensor should be placed in
the place which is not isolated and not exposed to atmospheric impacts.
After installation and connection, a sensor should have the function of
Weather sensor
activated in a controller menu.
To make sure that the valve works correctly, the set temperature is
set (behind the valve) for three intermediate external temperatures:
Set temperature threshold 1
-20
o
C
Set temperature threshold 2
0
o
C
Set temperature threshold 3
+ 20
o
C
Below, an example for the valve set as Type> floor:
Heating curve
– this is a curve, according to which the preset controller
temperature is determined, on the basis of external temperature. In our
controller, this curve is constructed on the basis of three points of set
temperatures for the respective external temperatures. Set temperatures
