Faulty timer?? or incorrectly wired??

[vinny048]

I have had probs with my heating ever since I moved into my house about 4 months ago, Gotta Baxi 105e, Seimens RWB7 timer and seimens room stat.

Everytime the timer comes on I have to turn the room stat up for the heating to kick in....which I understand the roomstat is doing its job.

However, yesterday I removed the RWB7 timer and could control the heating via the roomstat, I think having my timer is pointless.

I have bought the original baxi mechanical clock, tried that yesterday but it did no more than my current siemens timer does. I do know the clock is working as I left it for a couple of hours to see it was operating.

All I want is my heating to come on and go off 2 hours in the morning and 2 hours in the evening, without having to turn the roomstat up, if i leave the roomstat turned up the heating can run 24/7.

Is it that my timer is wired Incorrectly?

It does sount as if it may be wired wrongly.

However unless I checked the system and the wiring I cannot be 100% sure.

The fact that the installer tried to safe money by leaving the old timer is suspicious. Get someone to check the entire system. I would expect other electrical failures and sludge in the system amongst others. Will save you lots of hassle and money to sort that out before it is too late.

The timer was brand new along with the boiler and roomstat, the house was only built 3 years ago. This was a new installation, the worrying thing js the house belonged to one of the builders.

Certainly sounds wired incorrectly, even more so the fact it was the builders house

Oops, you should have mentioned that.
Sounds like a builder who thinks he know better than the plumber, buys the stuff wherever he can get it cheapest, flicks it on the wall and gets a bloke to sign it off on Saturday morning
Do you actually have the BENCHMARK? See if any of the measurements on there can actually be reproduced.
