Get Started
What do I need?
How do I get started?
The following installation guide will explain how to
fit the LightwaveRF Thermostatic Radiator Valve
(TRV) head to a radiator. It will also explain how to
link it to the LightwaveRF Smartphone or Web
App via the Lightwave Link.
To install the TRV (head), you will first need to
remove the existing one. This is usually
straightforward and does not require tools;
however, an adjustable spanner maybe useful if
the valve is tightly screwed down. The ‘Lightwave
Link’ and App is required to operate the
LightwaveRF TRV remotely.

Installation
• To attach the LightwaveRF TRV
(head) you will need to ensure that
you have a suitable thermostatic valve
fitted to your radiator (such as the one
pictured) and unscrew the existing
valve head. This can usually be done
by hand and does not require any
special tools.
NOTE: Removing the existing valve
head should not cause any water leaks
as the main body of the valve remains
sealed.
• The LightwaveRF TRV head will
screw fit the majority of existing
thermostatic valves without alteration.
There are, however, several adapter
collars provided to compensate for the
most typical variations in the diameter
of the valve and screw thread.

Quick Start Guide
Installation
The battery compartment is located at the top
of the TRV. Remove the cover and insert 2x AA
batteries.
Once the batteries are inserted, the TRV will
automatically calibrate itself (this can take up
to a minute). This requires it to be attached to
the radiator, therefore do not insert the
batteries until the TRV is securely installed. If
the ‘error’ LED lights up during calibration, the
TRV is not seated properly and may need
adjustment (see troubleshooting section).
Inserting the batteries / calibration
There are 2 types of collar (type A, type B). If
Type A fits the valve screw thread, this is the
more desirable collar to use. It has 4 insert pin
lengths options provided for the collar. The
most suitable pin is the one that (when in the
collar) replicates the length of the existing pin.
Type B provides a clamp fit around the valve body
and can be tightened using the screw provided.

Manual Operation
Understanding the indicator LEDs
Steady green ‘on’: TRV is opening the radiator valve
Steady amber ‘o’: TRV is closing the radiator valve
Alternating on/o (longer on LED): Linking mode
Alternating o/on (longer o LED): Unlinking mode
Steady red & amber: Valve jammed or wrong pin
Steady red & green: Not mounted correctly / wrong pin
Flashing red: Low battery (App should also report low
battery status).
Manual and remote operation
The TRV is designed to achieve a set room temperature by controlling the
flow of heat to the radiator. It is remotely controlled by the LightwaveRF
Smartphone App and Web App (you will also need the Lightwave Link). The
TRV automatically abides by the temperatures and schedules set from the
App. The TRV also has buttons to allow you to control the radiator manually.
If linked directly to the valve, a LightwaveRF Heating Remote or Magnetic
Trigger can also be used to control the radiator in place of or alongside the
App. The following section will show you how to use the manual buttons and
how to link the TRV to the App and to a Heating Remote / Magnetic Trigger.
Manual Operation
The Standby button
Standby button
NOTE:
When linked to the App, the target room temperature that the TRV
will achieve will be automatically set by the App (see App instructions to
learn how to set this) unless the ‘standby’ or ‘boost’ buttons are pressed.
Pressing the ‘standby’ button will fully open or close the valve, but ONLY until
the next scheduled change. At the next scheduled temperature change, the
TRV will revert to the target room temperature preset by the heating schedule.
The current target temperature, and the heating schedule for the TRV can be
changed at any time using the App.
Pressing the ‘standby’ button on the TRV
toggles between the fully open and fully
closed positions.
This will turn the radiator on
or o by enabling or preventing the flow of
hot water to it.
When the ‘standby’ button is
pressed, a green light will illuminate to
indicate that the valve is opening, or an
amber light will illuminate to indicate that
the valve is closing.
Manual Operation
Pressing the boost button on the TRV raises the target temperature a few
degrees above the current room temperature for the duration of one hour.
If the target temperature is already several degrees higher than the actual
room temperature, then pressing boost will simply match this temperature.
The Boost button
Using the Heating Handset
A LightwaveRF Heating Remote can be linked to a
TRV to directly control it (see handset
instructions).
Once linked, toggling the ‘standby’ button on the
remote will turn the radiator on and o in the
same way as the standby button on the TRV. The
boost button operates the TRV 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 room
temperature.
Device Setup
Linking the TRV to the Heating Remote or Magnetic Trigger
If you intend to use a LightwaveRF Heating Remote or
Magnetic Trigger to control the TRV directly then you
will need to ‘link’ them. The TRV can be linked to other
LightwaveRF heating devices using the following
method.
1. Press and release the ‘linking’ button on the TRV (the
on and o LEDs will flash alternately).
2. Press the linking button on the heating device you
wish to link. The ‘on’ LED should flash to indicate a
successful link.
To unlink a heating device from the TRV, press and release
the linking button and then press the ‘standby’ button. This
activates ‘unlinking’ mode. Press the Linking button on the
heating device you wish to unlink. The ‘o’ LED
should
flash to indicate that the devices have been unlinked.
To completely clear the memory of the TRV, 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.
App Setup
Linking the TRVs to the LightwaveRF Apps
To use the App or Web App to control
TRVs, 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 TRVs 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 TRV (the on and o
LEDs will flash alternately).
3. Send the linking command from the
App (the in-App instructions will explain
how to do this). The ‘on’ LED should flash
to indicate a successful link.
Using the App
Using the Home Thermostat with the App
IMPORTANT: For full instructions on how
to use the Home Thermostat with the App
or Web App follow the in-App help or visit
www.lightwaverf.com.
The main use of the Home Thermostat, if
linked to the LightwaveRF App and Web
App, is to be an accurate temperature
reference. You can still schedule the
heating and select modes using the
thermostat. It may be more convenient,
however, to do this from the App or Web
App on your smartphone/tablet. The
Thermostat now acts as a convenient
manual control to complement the App.
Importantly, the Home Thermostat and
App work together: when you change the
mode or schedule on the Home
Thermostat or the App, it will
automatically appear on the other device.

Add other Heating Devices
1. (Easy): Remote control of a single radiator
Required: TRV, Heating Remote
It is really comfortable and convenient to be able to have direct control over
the room temperature without having to get up and alter the thermostat or
boiler. This can be achieved quickly and easily using the LightwaveRF TRV
and Heating Remote. Installed in seconds, they can turn o the radiator in
the room and allow you to be comfortable without having to aect the rest
of the house heating.
Heating Scenarios
2. (Advanced): ‘Wet’ zoned heating
Required: TRVs, Lightwave Link, Boiler Switch, Home Thermostat
With the LightwaveRF App and the Lightwave Link you can create an
expandable zoned system that can take care of your entire home using TRVs
that fit ‘wet’ radiators. 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 AND electric radiators and
schedule them together for a totally integrated heating system!
Heating Scenarios
Problem: The TRV will not consistently operate remotely.
Solution: The Remote/Thermostat/Lightwave Link may be encountering
interference or may be at the edge of its reliable range of operation. First,
ensure that there are no large pieces of metal or bodies of water in the path
of the transmission. If the problem persists, try moving the devices closer
together.
Problem: The TRV ‘error’ LED flashes after calibration/operation.
Solution: The TRV is not calibrated correctly or may be jammed. This may
be because it is not mounted properly; check that it is screwed down
securely (finger tight) and not over tightened or cross threaded. If you are
using an adapter collar, try changing the length of pin being used (there are
four dierent lengths).
Problem: The TRV no longer functions and the LEDs do not illuminate.
Solution: Check the batteries. The average battery life should be at least
one year, although this will vary depending on use. A red error LED will flash
ten times to report a low battery status. If this measure fails, there may be a
fault. Please contact technical support via www.lightwaverf.com.
