What do I need?
How do I get started?
To install the Boiler switch, please follow these
instructions. You must also refer to the wiring
instructions specific to your boiler type which can
be easily downloaded at
www.lightwaverf.com/product-manuals or by
scanning the QR code below. The setup guide in
these instructions will then explain how to link the
Boiler Switch to the LightwaveRF Home
To install the Boiler Switch, you must understand
how to safely turn o the electricity supply and
be comfortable with following some basic wiring
instructions. You will also need suitable electrical
screwdrivers.

Safety Precautions
Installation
•
Prior to installing the Boiler Switch, read through the wiring instructions
provided thoroughly. Make sure that you understand your heating setup as
specified on the following pages.
•
Before proceeding with the installation, check and ensure that the boiler
is OFF and that no mains power is being received. Remember - the mains
terminals remain live even if the boiler’s on/o controls are switched o. If
a separate wiring centre needs to be accessed, make sure that no power is
being received. If in doubt always consult a qualified electrician.
•
Ensure that the Boiler is earthed.
•
Never take unnecessary risks if unsure, as damage can be caused by an
incorrect installation.
•
Do not strip the outer sheathing of flexible cables more than necessary to
prevent short circuits.
•
Ensure that all cords pass through the cable clamps in the rear of the
control box and are securely fixed. Ensure that the power supply is
connected such that the current carrying conductors become taut before
the earth conductor should the supply cord slip from the cable clamp.

Remove the backplate and cable clamp
To gain access to the wiring terminals on
the Boiler Switch, you must first remove
the backplate. This can be done by
loosening the two screws sited at the
base of the unit using a suitable
screwdriver. Once the screws are
loosened enough so that they protrude
from their screw holes, gently lift the
backplate away from the main unit and
slide it down. Once the hooks are free
from their mountings, the backplate
should slide free. Screws
Installation
Hook
Once the backplate has been removed, the
cable clamp needs to be unscrewed ready
to accommodate the wires. There are also
two capped holes situated at the base of
the unit. One of these (or two depending
on the number of cables used) needs to
have its cap removed using a suitable
blade so that the wires can pass through.

To know where to install the Boiler Switch, you will need to know the type of
heating setup that you have at home. Please identify your system and then
refer to the corresponding section after this page.
1. Combi boiler (most common) - In the vast majority of cases, your domestic
boiler will be a standard ‘combi’. It provides both hot water and water for
central heating directly. It may have an accompanying ‘room thermostat’
which is usually located in the hall.
2. Y plan system - this consists of a ‘system’ boiler which supplies both a hot
water tank and the central heating. There is a single motorised valve which
distributes heated water to either the hot water tank, the heating or both. It
will usually include a room thermostat.
3. S plan system - this also consists of a system boiler supplying both a hot
water tank and the central heating. In this case there are two motorised valves,
one regulating the supply for the hot water and one for the heating. It will
usually include a room thermostat.
4. Multi-zone system (S plan plus) - this is similar to the S plan system, but has
multiple motorised valves controlling supply to dierent heating areas or ‘zones’.
Understanding your heating setup
Installation

The setup show below is a standard combi system which is common to most
homes. Combi systems may or may not include a ‘room thermostat’ such as
the one pictured. This is wired into the room thermostat terminal. Even if
there is no existing room thermostat, a combi boiler will always include a
room thermostat (RT) terminal into which a thermostat can be wired. This is
where the LightwaveRF Boiler Switch should be connected (see next page).
