What happens if you incorrectly wire thermostat?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
Does switched live mean neutral?
Switched Live is only live when the switch is on (this is where it gets its name from). Note – the switched live has a brown sleeve on it, this highlights that the wire is actually a live wire, even though it is blue, this ensure that it is not confused with a neutral wire.

How does a live and neutral thermostat work?
The receiver is wired to the supply in the same way as a normal thermostat – live and neutral provide a power supply, and there is a switched output. The output can either be a single terminal which is live when heat is required, or ‘volt free’ terminals in which case there are two terminals for the output.
How does a wireless thermostat work in a home?
Wireless thermostats Provided as two components. The actual thermostat is a battery powered item which sends a signal by radio to the receiver unit. The receiver is wired to the supply in the same way as a normal thermostat – live and neutral provide a power supply, and there is a switched output.
