Siemens RDJ/10RF programmable thermostat

[terry004]

Hi I have just bought the Siemens RDJ/10RF programmable room thermostat for my central heating. What a waste of money and time, the timer doesn't work, and most of the time the central heater switch wont even turn my boiler on. I have tried setting and re setting the unit many times, but it seems too have a will of it's own, the electrician who fitted it has been back 3 times with replacement units but they are the same. Anyone got any ideas what I can do? any feed back would be much appreciated
regards Terry

have you tried relocating the transmitter, it may be getting some interference from some other rf source.

Hi Mick,

yeah I have tried locating it just about everywhere

i've fitted loads and yet to have a problem. there must be an installation issue. possibly interferrence. or if your really unlucky your supplier has a faulty batch. are you checking to see if the light goes on/off when you turn it up/down?

 

[terry004]

you mean the green light on the receiver?....yeah when that's on there is no probs, but if I leave the heating off for a couple of hours, or put the thermostat timer on, I notice the boiler hasn't fired up, when I look to see if the lights green on the receiver its red which means it isn't reading the thermostat transmitter, that's where I'm having the problem.

when I look to see if the light's green on the receiver, it's red

How far it the receiver from:

(a) The boiler?
(b) The transmitter?

How many walls/floors between receiver and transmitter?

Is the receiver connected to a permanent power source?

I had this before in some flats in Brighton, it was due to the metalwork in the building structure and it stopped the stat working over about 15metres.

the receiver is about 10ft away from the transmitter, there are no walls in between and they are on the same floor, the receiver is wired the transmitter is wireless and uses a battery

the receiver is wired the transmitter is wireless and uses a battery

I know that. In any case it wasn't what I asked.


Where, exactly, does the receiver get its supply, to the L and N terminals, from?

I have fitted loads, non have been a problem, I am thinking it's more likely an installation issue.

Bit late to reply, but in case it helps anyone else searching. Often the reciever is too close to the electronics of the boiler and this is where the interference comes from.
