I have an older combi boiler that has a mechanical timer control on the boiler but it's upstairs and after a recent injury I can't get up stairs (and won't be able to for several months ) so I was wondering if it was possible to install an electronic one downstairs to control it. I don't need anything too fancy - just on/off override will do for now, unless there's a simple option to add a programmable one.
I tried searching through the web site but came up blank on this query. Thanks for any help available.
The timer has to be incorporated into the boiler circuit otherwise the hot water may not work and anyway, the boiler requires a permanent live.
Who exactly can do electrical connections on the boiler is I believe a grey area. Many Gas Safe engineers (remember. it is not CORGI any more) don't feel able to wire boilers, whilst qualified sparkys are not allowed to remove the lid!
A typical wireless thermostat costs about £80 - £100 plus installation.
There is another way round this though. Do you have a room thermostat? You could replace this stat with the new style programmable stat and either remove or leave the timer upstairs on 24hrs.
Is there not a way of extending the current cable from the upstairs timer to a new downstairs position? In this way the sparky would not need to open the boiler, be gas safe, nor would you need a ch engineer, but would only need to be Part P registered.
UPDATE: Ariston technical support got back to me about this subject and thought I should post it here for anybody else who is looking into the options. It was more specific to our actual model.
"Yes an external control can be fitted to the external control connector
in the boiler. The switching must be Voltage free. An electrician or a
boiler engineer would do this. Danfoss make a good one at a reasonable
