Neutrals in room stats

[Leo21]

I was always lead to beleive that putting neutrals, in room stats on combis or conventional systems, helped the stat perform better. But today the guy that was helping me reckons it nonsense. After reading the instructions again , I think he might have a point.

Might be wrong but always thought neutrals were only needed for indication or really old mechanical stats with coils or bi-metal strips.

Some stats need them others not, the honeywells need them for the little heater in them (increases accuracy from +-2 to +-.5degC) the draytons need them to power the relay that switches out.

Obviously there are plenty of 2 wire stats around now where they are not required at all.

depends on room stats but most of honyewell and draytons do most of them will work but will be about 5dc off (room temp)

Interesting , I have nt fitted a wired stat for years and have one to do in the next few days , does it matter if the neutral from the stat goes into the neutral connection in the boiler or in the actual spur ?

Sorry Leo, not nicking you thread

The purpose of the neutral is to allow an anticipator to help switch on the boiler before the room drops below comfort conditions.

As others have already commented, the neutral/anticipator prevents excessive swings in temperature e.g. too hot, too cold - and maintains the room in a comfort band (17.5-21.5 degrees c).

In digital stats, there is now no need of a neutral.

That's what i was led to believe. But in the instructions it says you don't need one, that's how I tread it anyway.

Yep thanks shaun , i have seen it done both ways , I didnt really think it mattered

the only case it will matter is if you borrow a neutral from a different circuit will trip a rcbo etc
