Figure C-3: Motorised Actuator and 3-Port Valve
To correctly assemble the 3-Port Mixing valve you will need to:
1. Ensure the clutch of the motorised actuator is disengaged
allowing for free movement with the rotary handle. To
disengage, place a screwdriver into the slot available, press
down and turn clockwise. You will have disengaged when the
arrow is facing the direction of the hand. Refer to Figure C-2.
2. Ensure actuator scale plate is in position and set as per
Figure C-3. i.e. '0' to the right.
3. Fit the valve lever (supplied with the actuator) onto
the splined shaft end. Rotate lever clockwise as far as
possible. If necessary, remove and refit lever to point to
'0' position on the scale.
4. Unscrew, remove and discard the fixing screw and blue
handle attached to the supplied 3-port valve body.
! NOTE !
The body scale plate is reversible and should be checked
to ensure correct orientation.
5. Remove the scale plate from the valve body. Carefully prise
the circlip from the shaft. Lift the scale plate off, turn it over
and refit with the '0' in the 3 O-Clock position. Refit circlip.
6. Fit the grey drive adaptor onto the 3-port valve spindle and
turn until the pointer is facing the 0 position on the valve
body scale plate. (The drive adaptor will only attach in one
position).
7. Slot the Anti-rotation peg in place.

! NOTE !
If the Anti-rotation peg is not fitted the motorised actuator
will spin in place and not turn the valve as required.
8. Place the motorised actuator onto the valve aligning the
drive adaptor and ensure the Anti-rotation peg slots into the
actuator body.
9. Insert the fixing screw through the rotary handle and fasten to
a maximum torque pressure of 0.8Nm.
Reset the clutch of the actuator following step 1 to make the arrow
point to A (Auto). When Auto is enabled the rotary handle will be
locked in place.
C.3.2 WIRING
The electrical cable supplied with the actuator is connected as
follows
Table C-3: Electrical cable wiring
Colour Description
Brown 230V drive to open the valve
White 230V drive to close the valve
Blue 230V neutral
The motorised actuator is connected via the 2 lives and 1 neutral
connection to the wiring centre of either H2-M (Circuit 2) or H3-M
(Circuit 3). The live connections power the motor to move in either
direction to open or close the valve as required. Refer to Section 4
Figure 4-1 for wiring centre schematic.
For example for circuit 3
• H3-M On (Terminal 6) - Brown
• H3-M Off (Terminal 8) - White
