INTRODUCTION
A motorised valve is used to control the flow of water in a central heating system. The motorised valve can be
used for control of both heating and hot water, and it works by controlling the flow of water from the heating
boiler to other parts of the system.
There are two types of motorised valve used in domestic heating systems: two port (also called zone valves),
and three port (also called mid position valves). Salus Controls offers both types of valve in a range of standard
port sizes.
FEATURES
• Two port option in 22mm and 28mm sizes
• Removable actuator assembly
• Manual lever and position indicator
• Spring return
• Industry standard wiring

INSTALLATION
Please read the important safety information at the start of this manual before you begin to install the device.
Before Installation
This valve must only be installed in compatible systems. Before installing, please check that:
• The system pipework has been flushed out to remove any residue.
• There is enough clearance around the valve to allow removal and refitting of the actuator.
• The valve is not installed with the actuator facing down.
• The supply voltage is the same as the voltage indicated on the actuator cover.
• The mains water pressure and the pressure differentials between valve ports are suitable for this valve
(see Product Specification).
Do not restore the mains supply to the system until all associated items are fully installed.
NOTE: All electrical installation work should be carried out by a suitably qualified Electrician or other competent
person. If you are not sure how to install this motorised valve consult either with a qualified electrician, heating
engineer or your boiler / heating system supplier for advice on how to continue.
Electrical Connection
The electrical connections to the motorised valve are made using the pre-wired cable. This simplifies
installation, as no connections need to be made to the actuator itself. The connecting cable uses industry
standard colours, and the connection details are shown below:
Wire Colour Description Electrical Connections
Blue Mains Neutral
Brown Switched Live from Room
or Cylinder Thermostat
Grey Live
Orange Normally Open (NO)
Green / Yellow Earth

OPERATION
Two way valves
A two way motorised valve has port A normally
closed with no power to the valve. When the
electrical supply is activated, the actuator motor
overcomes the force of the internal spring and
opens the valve fully. This allows water to flow
from port A to port B.
The valve is kept in the open position until the
electrical supply is interrupted. When the
electrical supply is interrupted the internal spring
drives the valve back and closes port A.

MANUAL LEVER
There is a lever on the side of the actuator cover: this lever allows manual
operation of the valve, e.g. for refilling and draining of the system or if the
actuator fails. For two way valves, the lever allows the valve to be kept open;
with three way valves the lever allows both ports A and B to be open at the
same time.
To manually operate the valve, gently push the lever forward and latch it in
the MAN position. The valve will automatically return to AUTO when the actuator is powered up again.
NOTE: Push the manual lever slowly to prevent damage to the actuator motor and gear system.
The valve should be in manual position to be fitted.
ACTUATOR REMOVAL
AND REFITTING
The valve actuator can be removed or refitted without
having to disturb the valve installation. The actuator is
designed to clip onto the valve body, making removal
and refitting very easy.
Note: Do not attempt to dismantle the actuator
assembly as it contains no user serviceable parts –
dismantling or tampering with the actuator
assembly will invalidate the product warranty.

MAINTENANCE
The Motorised Valve requires no special maintenance. Periodically, the outer casing can be wiped clean using
a dry cloth (please DO NOT use solvents, polishes, detergents or abrasive cleaners, as these can damage the
thermostat).
There are no user serviceable parts within the unit; any servicing or repairs should only be carried out by Salus
Controls or their appointed agents.
Should the Motorised Valve fail to function correctly, check:
• The heating system is switched on.
• The lever is not latched in the MANUAL position.
WARRANTY
Salus Controls warrants that this product will be free from any defect in materials or workmanship, and shall
perform in accordance with its specification, for a period of three years from the date of purchase. Salus
Controls sole liability for breach of this warranty will be (at its option) to repair or replace the defective product.
