N - Neutral
L - Live call from programmer
3 - Call for heat to mot valve.

i would say your
blue is neutral
brown is live
g/y is sw/l

check with a multi meter.

thanks for the advice it is wired that way now and seems to work.
radiators are warmong up.
just confusing why when i first did it with wiring like this pump and boiler didnt fire up,when hot water was demanded it fired up!!!

i then selected 24hr on timer for c/h will check c/h in morn on its own to see if it works.

once again thanks

maybe you had a bad connection when you fitted the wires

 

[chrisdt1]

hope so

ill see tomorrow

its gone off now when i thought it would carry on

seems it turned off when the hot water went off

 

[seco services]

is the programmer still calling for heating ?

 

[chrisdt1]

yes programmed to come on up to ten pm

set thermostat to 25 degs

it went off coincidentally when it had heated a tank of water.

never had a prob before

only changed thermstat because it would only turn on above 30 degs

im a bit confused now dont know whats wrong withit

 

[chrisdt1]

could you tell me how to fix back my old thermostat at least it worked

i didnt take note where the wires came off but no 1,3 and 2 screws are loose

its a honey well thermostat

 

[seco services]

can't be much wrong.
have you got a multi meter ?

 

[chrisdt1]

no i dont

really need to get one

any ideas

 

[chrisdt1]

c/h switch on control box is set for 24 hr and thermo is set at max

no c/h

it worked when the boiler was heating water

very cofusing

 

[seco services]

thats that idea out for tonight.
does the stat click when you turn it up/down ?

 

[chrisdt1]

it does click

 

[seco services]

so its got live to it n0 1
so i would check n0 3 connection.

or remove 1-3 join them together with a choc bloc if boiler fires you know
everthing else is working.

 

[chrisdt1]

ill give it a go tomorrow

any ideas on the old thermostat wiring
