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.
