RoomThermostat Replacement Help

GK1 · 26 Aug 2006

I am replacing an old Honeywell T6360B rotary room thermostat with a digital (battery powered) Sunvic TLX 7501. I have uploaded pictures of the wiring for both of them.
Please advise on the correct wiring for the new Sunvic. The Honeywell has a Red Live (always 240v), a Yellow switched live (240v when thermostat goes to ON), and a Blue that remains at 0v al the time. The Sunvic has Common, ON, OFF terminals. Which goes where?

Many thanks.

Red in 3
Yellow in 2

Others not required (make safe)

off is just for cooling, say if you want to switch your live to a cooling device when the set temp is achieved. think of a cylinder stat when used with a `Y` plan(live to 2/grey) when stat temp achieved. S,Y.. W or what ever plan systems will not require live to cool just one common (live in) and one switched live(load)to the pump or 10 way j/b. Dont for get the neutral wire very important,stat needs this to work correctly.most room stats require 4 core, apart from one of the honeywell range (2 wires)

Ok. Thanks.

How do I loop the Neutral wire on the Sunvic - there's nowhere to connect to? At the Boiler end, Neutral (Blue) is used, but I don't see any route to the old Honeywell....

if the new stat doesn`t ask for a neutral just make the old wiring electricaly safe will a 5amp choc bloc.

GK1's new stat doesn't.

The guy is a diy'er

He won't have a clue what you are on about.

Plus the fact that it has no relevance to the stat that the OP has got.

yea my bad

plumber, I think you've got some useful knowledge to contribute, but, and I mean no offence, it's potentially being lost in a mixture of laziness and poorly thought out replies.

If you'd just take a couple more minutes to ponder your response, and perhaps read your words as if you were a novice, it would help a lot.

As I said, I mean nothing personal by this.

BTW, I have no idea what your above post meant.
