Safety precautions
•
Prior to installing the Electric Switch, read through the wiring instructions
provided thoroughly.
•
Before proceeding with the installation, check and ensure that no mains
power is being received. 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.
•
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.
•
Only use indoors
•
Not to be used as a fused spur

Remove the backplate and cable clamp
To gain access to the wiring terminals on
the Electric 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
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.

Controlling an immersion heater or towel
rail or other electrical devices
Installation
Link the mains cables to the Electric Switch as shown in the diagram. Be
aware, the first diagram assumes the switching of mains power NOT a volts
free system. The switch can also be used to switch volts free (useful for
curtains and door operators amongst others) as shown in the second
diagram. In such installations, mains live should NOT be connected to the
COM terminal; the volts free connections should connect to COM and NO
only. Note that the switch will still require mains power to the L and N
terminals for it to operate volts free.
The Electric Switch can be used to remotely turn on/o any connected
electrical devices up to 3000W. It can be set to operate thermostatically or as
an on/o relay only (see device setup section for details).
Any connected loads must be resistive loads such as immersion heaters,
towel rails, electric heaters, lighting circuits or electric gates. The switch is not
suitable for switching inductive loads, such as contactors, unless used with
an appropriate surge protector to prevent damage caused by electrical
surges.

Mounting the Electric Switch
It is recommended to mount the Electric
Switch to the wall next to the radiator or
device that it is controlling in a suitable
place.
The backplate includes two screw
holes which allow the plate to be mounted to a wall using suitable screws. Once
mounted, the main unit can be slotted
back into place and the screws tightened.
Once the cable(s) have been connected,
the cable clamp needs to be reattached in
order to secure them and to ensure that
they cannot become dislodged from the
terminal connections. The cable(s) should
run through holes situated at the base of
the unit.

Understanding the Indicator LEDs
Basic operation
The Electric Switch will allow a connected electric heater, towel rail or other
electrical device (maximum 3000W resistive load) to be turned on/o
remotely. It has an in-built thermostat which means that current temperatures are constantly monitored and reported. The Electric Switch can
operate a connected device directly, or be scheduled to switch on/o the
device once a set temperature is reached.
The Electric Switch can be controlled manually or by linking it to the
LightwaveRF Link and App to enable remote control from a smartphone,
tablet or PC. The following section will show you how to use the basic
features and how to link the Electric Switch to the App.
Steady Green ‘On’: The connected device is powered
Steady Red ‘O’: The connected device is unpowered
Alternate On/O (longer on LED): Linking mode
Alternating O/On (Longer o LED): Unlinking mode

The Standby button
Standby button
If not connected to the App, pressing the Standby button on the Electric
Switch toggles the connected heater or electrical device on/o.
When connected to the App, if the connected device is on, pressing the
Standby button overrides the current schedule and turns o the device
until the next scheduled ‘on period’. If the heating is o, pressing the
Standby button will turn the device on until the next ‘o period’.
Manual operation
Page 15
Pressing the Boost button on the Electric 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
an Electric Switch directly, or via a linked Home
Thermostat (see thermostat instructions).
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.

Linking to the LightwaveRF Apps
To use the LightwaveRF App or Web App
to control the Electric Switch, you will first
need to install the ‘Lightwave Link’. This
allows any LightwaveRF devices to be
linked to and controlled by a smartphone,
tablet or PC. The switch can be linked to
the App using the following method:
1. Download the App and follow the
in-App setup instructions to setup the
Lightwave Link and App. Access the
‘Heating Page’ and follow the instructions
regarding how to add a device.
2. When prompted, press and release the
‘Link’ button on the Electric Switch (‘link’
will flash on the screen).
3. Send the linking command from the

or visit www.lightwaverf.com.
The Heating Page allows you to view
every LightwaveRF Heating Device that
you have set up on the App. Displayed for
each device is its current temperature, set
target temperature and the next change
to be enacted by the heating schedule.
If you select a device, you can view more
options. From this screen you can change
the current target temperature using the
main dial. You can also view the heating
schedule for each day by selecting the
individual week days. To edit the heating
schedule for this device, select the ‘edit
schedule button’.
Setting up the LightwaveRF App
Page 18
Thermostatic or on/o control
Once you have linked the Electric Switch to
the App, you can chose how you want it to
behave.
The Electric Switch has the capability to
utilise its in-built thermostat to monitor and
set the temperature. This is its default
mode of operation.
If you want the Electric Switch to turn
on/o at a scheduled time only rather than
at a scheduled temperature, you can switch
from temperature monitoring mode to
on/o.
To switch between modes, select the relevant
Electric Switch from the heating page on the
App, and click on the arrows at the top right
corner of the screen. The current temperature reading should switch to an on/o
control which can also be scheduled.

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!

Q. Does the Electric Switch have a ‘standby’ power consumption
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. Can the Electric Switch work with a Home Thermostat?
A. Yes. An Electric Switch can link to a Home Thermostat where the thermo-
stat is acting as a room (not house) controller. The Home thermostat NOT the
Electric Switch should be linked to the App in this instance.
Q. Is it legal for me to install a LightwaveRF Electric Switch myself?
A. Yes, LightwaveRF products are fully legal to install in your own home.
Q. Is it possible to overload the Switch?
A. 13A (resistive load) maximum. loading applies and should not be exceeded.
Q. Can I use the switch as an on/o relay ?
A. Ye s. The switch can be used to turn electrical devices up to 3000W on/o
with or without thermostatic control.
