clock

[Joe 2017]

Raven heat combi boiler, the clock is faulty which is part of the boiler - model number tm6192. i was wondering how i could fit a external randal clock.

the ravenheat clock has 4 wires, what wire what. on the back on the clock it says:

1 - 2 input voltage
3 - 4- 5 contact rating.

any input please does 1 - 2 mean live/neutral

what is 3 - 5.

thanks

Raven heat combi boiler,

that narrrows it down to about 10

yes maybe it does but most combi boiler clock are the same, it has a live and neutral, maybe heating on/off

yes it does

possibly 1-2 l /n 3/4/5 no/com/nc

but if your gonna fit an external clock it don't matter

why won't it matter, i just assumed i could take the wires off the old clock and rewire it to external clock

oh no you don't (well its nearly panto time)

external clock is wired off the boiler terminal block

model would be a great help

ravent heat rsf820/20T gc number 4758105. am assuming 1 is live, 2 is neutral, what about the other two. and why can't i just rewire it by taking the old clock wire, extending them and into new clock

c & d are the switch connections and are also on the terminal block of the boiler

thanks for that, makes it alot easier now, would you link it on the pcb or from the old clock

 

[kevplumb]

tbf it don't really matter how

it's easier to do it from the terminal block (i think)
