DigiStat 3

[dhutch]

Currently I have to control my heating by switching the boiler and off manually as it doesnt include a timer and ther thermostat/timer in the hall way (a DigiStat3) isnt wired in, no wire visable at either end!

Firstly, assuming its switch still works (its all lit up, keeping time, etc) I see no reason to buy a new one? its a bit complex to program but having had a stab before finding out it wasnt atached im fairly at home with it now.

Secondly, what cable is required, presumably although its a no-voltage switch in a compleatly plastic enclosure its better to use a lenght of Triple and earth with the earth coiled up, than to try and use the earth of a lenght of Twin and earth, or is that acceptable is suitable sleaved (ie, not sleaved in yellow/green) at each end?

Why was it installed if it wasnt wired?
There will be no wires at the part you have pictured.
There will be wires at the other end, are there lights at the other end (receiver).?

Do you have the instructions to programe it?

The boiler (Main HE 30) is fairly new, so I assuming when it was installed the thermosat wasnt wired into it. Why there then isnt a wire out the back of it, going somewhere in the direction of the boiler i dont know, this is what i was expecting, but having taken the t/stat off there are no wires present at all.

Have the fittng and operating manual (emialed drayton for it).

Lights?

Are you saying that the receiver isn't wired? Your picture is the room stat/transmitter, which wouldn't have any wires, just batteries underneath.

Something like 1.5mm twin and earth is OK for the receiver. The earths won't be needed for either mains supply to receiver, or switching wires from receiver to boiler or system wiring.

Install instruction here, wouldnt have thought it was that difficult.

You showed picture of digi 2, yet talk of 3.
I think the wiring is the same

Have you found a receiver?

Doesnt need power as its the battery model.
Is the stat/timer not jst going to be wired to the boiler?

The receiver IS wired to the boiler (or should be)
The tramsmitter (your picture) is fitted with batteries & transmits a radio signal to the receiver.

Your stat/transmitter sends signals to the receiver in my picture to turn the boiler on or off. The receiver in my picture should be wired into your boiler.

Have you found the receiver yet? Poss near boiler.

Sorry, think we;re at crossed purposes. As far as i can tell (and correct me if im wrong) what i have is battery model of a wired stat.
- Ie, there is no power feed to the unit, but it still have the three 'common', 'call for heat' and 'heat satified' wires.

Presumably designed to replace passive thermostat-only devices without runing extra wires.

That said, although its not far, given it appears someones pulled the wire out there would be an agurment for bining the DigiStat3 (which i couldnt find a photo of, but looks like the 2 photoed, as aposed to a new DigiStat3+) and fitting a wireles one to save me the hassle of rerunning the wire.

Are the wireless ones any good.


Daniel

 

[Diyisfun]

Wireless ones are no problewm.
You still need something hard wired at the receive end.

Sounds fair. I understand i would still need to hard wire in the receiver end, but it can presuambly be local to the boiler, hence limited wire run required. Transmission distance would be about 4m with only a party wall and thin door between.

 

[Whitespirit66]

Ah, talk of one model, and picture of another has confused me. Not difficult.

Not wireless version.

Just 2 wires to stat. One to C, other to ON. Connect other ends to boiler's stat connections, and remove link.

1 or 1.5mm cable or t and e is fine.

Got there in the end!

Ah right, because I dont need a wire to the 'Satisfied' terminal! Ofcause. A lenght of 1mm T&E it will be.

Got there in the end indeed! Thankyou.

No, Satisfied/off terminal not required for combis.
