vaillant 140 timeswitch

[saintsman36]

hi all, can anyone advise me whether changing a vaillant 130 timeswitch to a 140 in a ecotec 831 combi boiler is straight forward?. Is it a case of unplugging the 130, plugging in the 140 and programing it. Also how do you set up the warmstart feature?. The reason im changing is because the clock on the 130 keeps stopping,
Thanks

Yes, it is simply a matter of turning the power off and prising the old one out and plugging the new one in. To set it up follow the instructions in the box.
