Mend Valiant Randall 105 Combi Boiler Heating Replacement

My timer on my Valiant combi voiler?

My Valiant combi bioiler has an old fashioned Randall 105 dial timer which is now broken. I can either have the heating on or off!

Can the dial timer be chaged to a modern one like you can buy in BandQ, can i do this myself and how much would it cost if not?

Thanks

Hi Adam

If the timer is a 103 you can buy a modern replacement 103e, this slots straight onto the old backplate without altering any wires.

most combi heating wiring is a live out of boiler into time clock then a live back to boiler when time clock demands so yes it should be a pretty simple swap.

generally timeswitch will have a common connection (live) and a load connection (switched live).
