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.

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.
Holes
Clamp
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 dierent 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).

Download your boiler manual from the support menu
Please continue to follow the general instructions provided here, whilst referring to your boiler manual to find the exact location of the appropriate terminals described. You should, most importantly, refer to the main boiler wiring diagram for circuit wiring information. If you have a Y plan, and S plan or a multi-zone system that utilises a wiring centre, then you will need to refer to the generic wiring diagrams in this manual for guidance. If you are unsure about your wiring configuration, consult an electrician or heating
engineer.
Access the boiler wiring centre
The Boiler Switch needs to be wired to the room thermostat (RT) connection. In order to locate this, you must gain access to the boiler wiring centre inside the boiler. You should refer to your specific boiler manual to find out how to do this. Make sure that you turn o the mains power to the boiler.
In a standard combi, the wiring centre is usually located behind the front
Install 1: combi boiler
Quick Start Guide
Install 1: combi boiler
Once you have accessed the wiring centre, you need to locate the room thermostat terminals. You will need to refer to the main ‘PCB’ wiring diagram in your boiler manual.
The connections should usually be marked as ‘room thermostat’, ‘RT’, or, in some cases, ‘temperature sensor’ or ‘TS’. Be aware, however, that the terminology in some boiler manuals may vary. There may be a ‘jumper’ (small loop of cable) connecting the two terminals, as in the diagrams below. This needs to be carefully removed. If this terminal already has an existing thermostat connected to it, then this should be disconnected.
Locate the room thermostat (RT) terminal
Example Alpha and Vaillant Boiler wiring diagrams with correct terminals circled.
The simplest way to connect the Boiler Switch to the boiler is to use a single 5 core cable; however, a 2 core cable can be used to connect to the room thermostat terminals and a separate 3 core to the power terminals if necessary. This may be more appropriate if the terminals are further apart. Ensure that there is enough cable to reach from the boiler to the Boiler Switch when wall mounted.
Install 1: combi boiler
Prepare the cables
The Boiler Switch also needs to take mains power from the boiler. This can be routed from live, neutral and earth terminals located in the wiring centre. You should refer to your boiler manual to locate them.
Locate mains power terminals
The terminals are usually located next to or near to the ‘room thermostat’ connection. The picture on the right shows the arrangement of the mains (marked L & N) and room thermostat terminals (marked 3 & 4 shown by the loop of wire) on a typical Vaillant combi
Quick Start Guide

Install 2: Y plan
2. Wiring to a Y plan heating system
The basic diagram below shows the main constituent elements of a Y plan system which is common in larger houses. The system boiler produces hot water which is stored in the tank and/or circulated in the central heating system. A motorised valve allows flow to the tank, the radiators or both together. A room thermostat controls the flow to the heating by opening or closing the valve. This thermostat needs to be disconnected at the wiring centre and replaced by the Boiler Switch.

Install 2: Y plan
Access the wiring centre
The Boiler Switch needs to be wired in place of the existing room thermostat. In order to locate this connection, you must gain access to the system wiring centre. This is often located near to the hot water cylinder. Make sure that you turn o the mains power. The connections in the wiring centre for a Y plan setup are usually to a standard format. A typical example (Honeywell system) is shown in the diagram on the next page.
Once you have accessed the wiring centre, you need to locate the room thermostat’s connecting wires, and terminals that they are connected to. There should be two main switching wires (usually white and black). In some cases there will also be a neutral connection (usually blue). Make a note of the locations before disconnecting the wires, as they may not be marked.
Locate mains power terminals
The Boiler Switch also needs to take mains power. This can be routed from live, neutral and earth terminals located in the wiring centre (see the example in the diagram). The terminals are usually located next to or near to the room thermostat connections. Take extreme care when dealing with live mains; if unsure always consult an electrician as an incorrect install could result in damage being caused.

Understanding the Indicator LEDs
Basic Operation
The Boiler Switch is designed to turn your boiler on and o. It is designed to be ‘linked’ to, and controlled by, the LightwaveRF Home Thermostat. The Boiler Switch will then automatically abide by the temperatures and schedules that you set from Thermostat. If the Home Thermostat is linked to the Lightwave Link, you will also be able to control and schedule your Boiler from your smartphone using the LightwaveRF App.
This section will show you how to setup the basic functions of the Boiler Switch. The following section will show you how to link the Boiler Switch to a Home Thermostat in order to integrate it into your heating system. To
achieve smartphone control of the Boiler, it must normally be linked to a LightwaveRF Home Thermostat which in turn must be linked to the Lightwave Link.
Steady Green ‘On’: The boiler is on
Steady Red ‘O’: The boiler is o
Alternate On/O (longer on LED): Linking mode
Alternating O/On (Longer o LED): Unlinking mode
Manual Operation
The Standby button
Holding the Standby button for a couple of seconds activates ‘Away mode’. Away mode also reverts to a pre-set setback temperature; however, rather than returning to the schedule at the next on/o period, the mode will continue to remain active until it is manually cancelled by pressing the Standby button. The Standby setback temperature and Away mode temperature is also stipulated by what is set on the Thermostat. These functions can also be carried out on the App.
Manual Operation
Standby button
If not connected to a Home Thermostat, pressing the Standby button on the Boiler Switch toggles the Boiler on and o. Once the Boiler Switch is linked to a Home Thermostat, pressing Standby will toggle between the set ‘on’ and ‘setback’ temperatures stipulated by this device (see Home Thermostat and App instructions to learn how to do this).
When connected to a Home Thermostat, if the heating is on, pressing the Standby button overrides the current schedule and turns o the heating (activates setback temperature) until the next scheduled ‘on period’. If the heating is o, pressing the Standby button will turn the heating on (activates on temperature) until the next ‘o period’.
Pressing the Boost button on the Boiler Switch raises the target temperature several degrees above the current temperature for the duration of one hour. If the target temperature is already several degrees higher than the actual temperature, then pressing boost will simply match this temperature.
The Boost button
A LightwaveRF Heating Handset can be linked to a Boiler Switch via a Home Thermostat.
Once linked, the Standby button on the Handset will toggle between Running and Standby modes in the same way as the Standby button on the Switch. The Boost button operates the Switch Boost button.
The plus and minus arrows on the handset will raise or lower the target temperature a few degrees above or below the current temperature.
Using the Heating Handset
Manual Operation
Linking the Boiler Switch to the Home Thermostat
In order to schedule your heating and to use the heating remotely, you will need to ‘link’ the Boiler Switch to the LightwaveRF Home Thermostat. The Boiler Switch can be linked to the Thermostat using the following method.
1. Press and release the ‘Link’ button on the Boiler Switch
(the on and o LEDs will flash alternately).
2.
Press and release the ‘Link’ button on the Home Thermostat. ‘Link Ok’ should appear on the display to indicate a successful link
.
To unlink a Home Thermostat, press and release the Linking button on the Boiler Switch and then press the Standby button. This activates ‘unlinking’ mode. Press the Link button on the Thermostat. The ‘deleted’ should flash on the screen indicate that the devices have been unlinked.
To completely clear the memory of the Boiler Switch, press and release the Linking button. Then hold the Linking button until the LEDs flash rapidly. Finally, press and release the Linking button once more. The O LED should flash.

Required: Boiler Switch, Home Thermostat, Heating Remote
It is really comfortable and convenient to be able to have direct control over the house temperature without having to get up and alter the thermostat or boiler. This can be achieved using the LightwaveRF Home Thermostat, Boiler Switch and Heating Remote. You can turn the temperature up and down, boost the heating for an hour or simply turn it on/o. Use the Remote to control the Home Thermostat from the comfort of the sofa, and this will, in turn, relay the commands to the Boiler Switch.
Heating Scenarios
2. (Advanced): Zoned Heating
Required: TRVs, Lightwave Link, Boiler Switch, Thermostat etc.
With the LightwaveRF App and the Lightwave Link you can create an expandable zoned system that can take care of your entire home. Temperatures can be set for each room or ‘heating zone’, and heating can be planned week by week and room by room. If you have electric radiators, you can still achieve this by connecting them to Electric Switches. You can also link wet radiators, using TRVs, AND electric radiators and schedule them together for a totally integrated heating system!
Heating Scenarios
Heating System Setup
Q. Does the Boiler Radiator Switch have a ‘standby’ power comsumption? A. The Switch has a standby power consumption of approx. 0.5W. This is
because the in-built radio receiver requires power in order to receive commands. This rate is low & well within government energy guidelines.
Q. Does the Boiler Switch have to work with a Home Thermostat? A. Yes. The Boiler Switch must link to a Home Thermostat to operate.
Q. Is it legal for me to install a LightwaveRF Boiler Switch myself? A. Yes, LightwaveRF products are fully legal to install in your own home.
Q. Is it possible to overload the Switch? A. 7A max. loading applies and should not be exceeded.
Q. Can i link more than one Boiler Switch to a Thermostat? A. No. The Boiler Switch is designed to be controlled by a single thermostat,
and each Home Thermostat is only capable of being linked to one Boiler Switch. More than one Boiler Switch can be contrlled on the App (eg in a multizone system), however, each one must have an accompanying Thermostat.
Q. Can i use the Boiler Switch to control Hot Water? A. We recommend using the LightwaveRF Electric Switch to control your hot
water system.
