OPERATION |
|
MOUNTING |
|
|
The valve controls a mixing water temperature with a rotating |
|
|
||
plug. The plug adjusts with two control curves the water flow |
|
|
||
of two inputs. The required flow water temperature is reached |
C° |
|
||
by adding a proportion of return water to the boiler hot water. |
|
|||
|
|
|||
For optimum control performance, the DR has special control |
|
|
||
characteristics. |
