1. Introduction
A 3-way zone valve with electric actuator (230V, 50Hz), permitting manual control. It is usually
used in heating and solar thermal systems. The actuator is attached to the valve with four M5 nuts
(spanner size 8) and can be removed without the need to remove the valve. The valve does not
interrupt the ow of uid through the common port during switching. The direction of uid ow is
indicated by the actuator control lever. Fluid can ow in either direction through the valve (common
port can be used either as inlet or outlet).

Direction of ow through the valve
Direction of ow through the valve is indicated by the actuator control lever or by the groove on the
valve spindle visible after removing the actuator:

3. Actuator
3.1. Actuator Electrical Wiring
The actuator is controlled by the switching contact of the controller or thermostat (single-pole
connection) 230V, 50Hz. Permanent power supply is applied to terminals 1 and 2. The switched live
is connected to terminal 3.

3.2. Actuator Control
The actuator can be switched between automatic and manual mode. In automatic mode, its direction
of rotation is indicated by light indicators. In manual mode, the valve can be turned using the control
lever.
The control lever shows the position of the valve using the coloured eld. The colour of the uid ow
direction on the label corresponds to the colour indicated by the control lever.

3.3. Actuator Placing
The default position of the actuator is such that the valve can be installed in the piping without
removing the actuator. If required, the actuator can be removed and tted in a di󰀨erent position
(in quarter turns) - see the g. The label shall be then carefully removed and rotated to the correct
position according to the ports arrangement.

4.1. Valve Adjustment Options
A) Factory adjustment
The default setting of the actuator is with the lever turned into the blue eld (OFF position). After the
switched live is connected (ON), the valve turns clockwise and the red eld is shown by the lever. Af-
ter the switched live is disconnected (OFF), the valve returns to its default position. A label showing
the uid ow direction in colour corresponding to the lever position is placed on the actuator.

B) Swapping the ON and OFF positions of the valve
If necessary, the ON and OFF valve positions can be swapped. In the default position (OFF) the
lever will be turned to the red eld. After the switched live is connected (ON), the valve turns anti-c-
lockwise and the blue eld is shown by the lever. After the switched live is disconnected, the valve
returns to its default position (OFF).
How to change the default position of the valve
1. Switch the actuator to manual mode and turn the lever by a quarter turn into the red eld.
2. Change the direction of rotation of the actuator according to Chapter 6.
3. Switch the actuator to automatic mode.
4. Remove the label from the actuator and replace it with the enclosed label showing the
corresponding setting.

5.1. Valve Adjustment Options
A) Factory adjustment
The default setting of the actuator is with the lever turned to the blue eld (OFF position) and the uid
ows straight through the valve. After the switched live is connected (ON), the valve turns clockwise.
The lever is turned to the red eld and the uid is directed through 90 degrees in the valve. After the
switched live is disconnected (OFF), the valve returns to its default position. A label showing the uid
ow direction in colour corresponding to the colour corresponding to the lever position is placed on
the actuator.

Other Adjustment Options
The default valve adjustment can be changed in three di󰀨erent ways.
B) Swapping the ON and OFF positions of the valve
If necessary, the ON and OFF valve positions can be swapped. In the default position (OFF) the
lever is turned to the red eld and the uid will be directed through 90 degrees in the valve. After the
switched live is connected (ON), the valve turns anti-clockwise, the blue eld is shown and the uid
will ow straight through the valve. After the switched live is disconnected, the valve returns to its
default position (OFF).
How to change the default position of the valve
1. Switch the actuator to manual mode and turn the lever by a quarter turn to show the red eld.
2. Change the direction of rotation of the actuator according to Chapter 6.
3. Switch the actuator to automatic mode.
4. Remove the label from the actuator and replace it with the enclosed label showing the
corresponding setting.
