What is RT connection on boiler?
If your diagram shows “RT”, then these are the ports for an external Room Thermostat. This is where the connections go for our Boiler Switch unit. It would be the same terminals as where any previous hard wired room thermostat would have been, if applicable.
What does RT mean Vaillant boiler?
The RT is a terminal into which the thermostat is wired.
What is eBUS connection?
eBUS connection allows the boiler to modulate, ensuring peak performance and optimum efficiency. for a Glow-worm heating system. Enhanced load compensation.
What is volt free switching?
A thermostat or timer with ‘volt-free contacts’, or ‘volt-free switching’, operates a switch that opens and closes its contacts, but no voltage or current will flow.
What connections does a boiler need?
You will find seven pipes attached to the boiler:
- A gas supply pipe.
- Mains cold water inlet.
- Hot water outlet.
- Central heating flow pipe.
- Central heating return pipe.
- Pressure relief pipe.
- Condensate pipe.
How do I connect a wireless thermostat to my boiler?
To connect a smart thermostat to your boiler, the thermostat will require a power source (battery or wired), as well as a receiver box if one is required. Use the screen and the buttons on the thermostat to navigate the system. In some cases, both devices will automatically connect when they are turned on.

EBUS (endobronchial ultrasound) bronchoscopy is a procedure used to diagnose different types of lung disorders, including inflammation, infections or cancer.
How does a no volt switch work?
What cable do you use to wire a boiler?
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.
Should a boiler have its own circuit?
It’s best to have the boiler on its own circuit as if the installation is 17th regs then a ring main fault would lose your heating too so recommend depending on cable routing it has separate rcbo and isnt then prone to nuisance tripping because of fault on other circuit.
How many wires does a 2 port valve have?
2 Port Valve Electrically, the valve has 5 wires: Green/Yellow, Earth – connected to the metal body of the valve.
What Colour is the switched live wire on a 2 port valve?

How do you wire a lightwave switch?
At the first switch, move all wires fitted to L1 to the L terminal on the Lightwave switch. Move all wires fitted to L2 to the X terminal on the Lightwave switch. Move all wires fitted to C to the L terminal on the Lightwave switch. At the second switch move all wires fitted to L1 to the L terminal on the Lightwave switch.
How do I wire the boiler switch?
How do I wire the boiler switch? The Boiler Switch gets installed into the “Room Thermostat” cables on the boiler wiring diagram If you have an existing external wired thermostat, it will replace the cables placed there We’re unable to advise on specific boilers legally, as we are not heating engineers or electricians.
How many Lightwave dimmers do I need for my switch?
It requires one Lightwave dimmer and up to 6 Lightwave 2-way dimmers. Each requires power and a direct connection between the S terminals on each device (do not insert the live into the S terminal). In a standard 2-way switching arrangement, you may find that there is an L1 and L2 cable used.
Can a boiler switch replace a wired thermostat?
If you have an existing external wired thermostat, it will replace the cables placed there We’re unable to advise on specific boilers legally, as we are not heating engineers or electricians. The boiler switch will make and break connections between the NO and COM terminal.
