Wooster Bosh problem
chippy
<b style="color:pink;">Global Moderator</b>
My central heating is out of it's guarantee period and the controller had developed a problem. It's the DT10RF controller. It keeps losing the radio signal. For over a year the display has been showing 4 bars for a good signal but a week or so ago I noticed it has dropped to 2 bars which means poor signal. It keeps dropping connection. I've changed the batteries a couple of times to no avail. I moved it from the lounge to the hallway which cured it for a couple of days, then had to move it to the kitchen where the boiler is. Now the signal has become weak in there too. I don't want to buy a replacement as they are about £150 if it's only going to last a year or so. Any suggestions for a remedy?
I've googled the problem but all I can find is other people complaining of the same problem and no solutions.

by the way this is why I never suggest wireless t-stats etc....
Yeah I was advised against it, but I thought wtf does a sparkie know.

Let me know because I dont want to research the wrong thing. I did find replacement parts for the t-stat, but I noticed something about the batteries.
It says that this t-stat came with a LR6 batteries

If you look at the chart bellow the lr6 batteries have a Capacity under 500mA constant drain of 1800-2600 mah
which could mean if you put a battery which doesn't match the Capacity under 500mA constant drain it might not be able to keep up with the constant drain and it may make the signal grow weaker with the battery drain. I may be way off, but for the price of getting new doubble a batteries its worth a shot
*edit*
It does say in the service guide to make sure the batteries are the correct type..Which is the LR6
You cant expect to put a lawn mower battery in a car and expect it to run. There is a reason why they used the lr6 and not the r6. The t-stat probably needs the power that the lr6 can constantly produce. If you put a battery that doesn't have enough output it may be your problem.
