Fernox F1
Adding inhibitor protects your heating system by preventing corrosion, sludge and limescale.

It helps your boiler run quieter, heat your home more efficiently, last longer, and greatly reduces the risk of expensive breakdowns, repairs and premature replacement.

The Correct Answer is:-

All 230vAC (Analogue) room stats must have the following 4 wires.

Common (The wire from the programmer (CH ON) often T4

Switched Live (The wire goes to a valve [brown / white wire] to move the motor,
or to a combi Boiler SW.L to ignite.

A Natural (Blue)
An Earth (Yellow-Green)

No one got the error of when a BLUE or EARTH wire is carrying voltage
230vAC, it MUST be sleeved or coloured insulating tape to show itโ€™s LIVE!!!๐Ÿ™€
