Newbie in need of some help

[Alex88]

Hi guys, wondering if any one can help me please

Our central heating kicks on randomly at seemingly whatever time it likes and turns on the radiators. We live on a newish estate and I bet our neighbors have the same central heating system and programmer as ours, could it be that their timer is turning ours on? Our radiators (upstairs and downstairs) are on a timer unit and come on at times not set on the timer. Boiler is a Megaflow 2 System 12 compact GA, and the unit is a Salus Ep200.

Thanks in advance

Tried talking to them?

 

[Alex88]

No I haven't as wasn't sure it was even possible and didn't want to sound a bit daft. Is it possible?

It is possibly for rf type thermostats to interfere with others. They come with options in the back of the thermostat to change the rf frequency to help prevent this.

The Salus EP200 is not, AFAIK, a wireless device so interference from a neighbouring system is not going to be the problem. The installation manual for it is here:

The most likely cause of the problem is that the thing hasn't been programmed correctly, so you need to check that. Remember that there are several programmes depending on which day of the week it is.

Next thing to check is whether there is a 'frost protection' or 'minimum temperature' setting on the programmer or boiler that has been set too high, i.e. above 10°C.

Good spot, I saw the pic on Google and as I've only fit the rf units that's the reason for my post

I reset both the upstairs and downstairs and set the timers accordingly and correct, even on a hot day, they would still come on so not sure its frost protection.

 

[Alex88]

Even with frost protection, would that then turn on the upstairs radiators and not the downstairs ones?

If you have two timers, swap them over and see if the fault moves from upstairs to downstairs or stays where it is. If the former, you have a bad timer. If the latter, you need to look elsewhere.

The one downstairs is wired in to the wall and controls the radiators and water, the one upstairs is also wired in to the wall and does just the radiators so dont think swapping them is an option

Listen to the advice. They all have backplates.

Ok but what would happen to the water program?

 

[Welder]

The programmes go with the timer.
What you are going is proving a concept.
Do the bits of kit work at the times they should?
If the problem moves with the timer the timer is at fault. If it doesn't then the problem is elsewhere.
