What does the LightwaveRF Boiler Switch do?

The LightwaveRF boiler switch is part of LightwaveRF's home automation range. It is designed to function exclusively with the LightwaveRF smart thermostat. The thermostat communicates via RF (radio frequency) to remotely control the activity of the boiler switch, switching on the heating when the air temperature falls below the thermostat’s settings.

Will the LightwaveRF Boiler Switch work with my existing system?

The LightwaveRF boiler switch is compatible with different systems and setups. It can be used to replace the existing switch on standard combi boilers, whether they are Y, S or multi-zone systems. Any setup of a LightwaveRF boiler switch requires the LightwaveRF smart thermostat (N80QJ), as the boiler switch is essentially a receiver and does not function independently.

Multizone boilers require additional boiler switches for each zone, alternatively multi-zone central heating can be achieved with the use of LightwaveRF's radiator valve (N81QJ)

How do I install the device?

The LightwaveRF boiler switch is a direct replacement to the basic time clock or blanking plate. The boiler switch must be installed with compliance with the guidance provided in the current IEE Wiring Regulations and current Building Regulations. The installation of the boiler switch includes connecting a selection of wires inside the boiler and wiring up power to the boiler switch itself.

Once installed it only needs to be paired with the LightwaveRF thermostat (N80QG), which can be linked within minutes, providing you with a reliable and affordable solution to smart heating.

can this rf switch be used to switch another rf switch 40 metres away to turn on 240 volt boiler

Asked by: gaz1
This is not designed to work in this manner, it is only designed to receive the signal from the LightwaveRF thermostat (N80Q) and adjust the boiler settings (and LightwaveRF radiator valves if installed) accordingly.

If connected to a combi boiler and paired with the thermostat, would the boiler still provide hot water all day or only when the heating is on?

Asked by: Adam
This would provide the user to have hot water throughout the day .

What does the boost button do please? Sounds obvious, but is it? Is it just to switch it on for a short period, and then automatically cuts it off? If so how long? Thx
Asked by: Andy
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.
