INSTALLATION & OPERATING INSTRUCTIONS

1. Valve positioning

Install the valve so the actuator head is not below the horizontal level of the pipework. The open vent and

cold feed must not be isolated. The ow must be in the direction of the arrow. (from the centre port to either
Port A or Port B).

2. Fitting the valve body to the pipework

Fit the valve body using the nuts and olives provided. When tightening the compression nuts ensure that

only the valve body is used for grip. Take care not to overtighten.

3. Removal of actuator from the valve body

To remove the actuator head from the valve body ensure that the manual override lever is in the manual

position. Remove the two screws that x the actuator cover to the base. Remove the actuator cover. Remove
the two screws that x the base to the valve body. Remove the base of the actuator.

4. Fitting of actuator to the valve body

Before tting the actuator, please ensure that the maual override lever is in the raised manual position and

the xing screw is loosened. The actuator is mounted by aligning the 4mm at spindle on the valve body to
the identically sized slot on the actuator. Tighten the two xing screws on the base of the actuator. Fit the
actuator cover and tighten the two screws to hold the cover in place.

Once the valve is tted, place the manual override lever in the raised manual position. It is now possible

to ush and drain the system to remove any foreign matter. The system can now be relled and corrosion
inhibitor may be added if required.

5. Wiring Connections

5.1 The 1.2 metre cable can be connectd as follows:

WIRE COLOUR DESCRIPTION

Blue Neutral supply

Orange

Grey Hot Water OFF from cylinder stat or OFF from programmer

White Central Heating ON from room stat or ON from programmer

Yellow / Green Earth connection

Hot Water ON from cylinder stat or ON from programmer
Also connect to boiler and pump live.

CAUTION!

 Ensure that no more than a 3A fuse is used to supply all controls.
 It is not permissible to use any voltage other than 230V on the auxiliary switch.
 Electrical installation must conform with current I.E.E. regulations.

5.2 For use as a Diverting Valve, see table below:

ELECTRICAL CONNECTION CABLE CONNECTION VALVE POSITION

Not connected Not connected Hot Water “Port B” open.

230V connected to Orange core Hot Water “Port B” open.

230V connected to Grey core Hot Water “Port B” open.

230V connected to White core Mid position “Port A” and “Port B” open.

230V connected to Grey & White cores Central Heating “Port A” open.

6. Commissioning

Once the system has been lled and vented, ensure the manual override lever is in the auto position.

7. For Hot Water only

Switch the Central Heating ‘OFF” at the programmer or set the room thermostat to the minimum. Switch the

Hot Water “ON” at the programmer and set the cylinder thermostat to the maximum. Port “B” should open on
the valve. The boiler should re and the pump should run. The pipe connected to Port “B” should get hot.

8. For Central Heating only

Switch the Hot Water “OFF” at the programmer or set the cylinder thermostat to the minimum. Switch the

Central Heating “ON” at the programmer and set the room thermostat to the maximum. Port “A” should open
on the valve. The boiler should re and the pump should run. The pipe connected to Port “A” should get hot.

9. For Hot Water and Central Heating

Switch both the Hot Water and the Central Heating “ON” at the programmer. Set both the room thermostat

and the cylinder thermostat to the maximum. The valve should go to the mid position with both Port “A” and
Port “B” open. The boiler should re and the pump should run. The pipes connected to Port “A” and Port “B”
should get hot.

Once satised with the valve operation, reset the programmer and the thermostats to normal control

settings.

WARNING!



Under no circumstances should the actuator be insulated or covered by any other material.

 Lack of ventilation will cause the actuator to heat up beyond the maximum permissible ambient temperature

of 50˚C.
