heating/boiler advice, honeywell thermostat - what is my state?

[bob999]

please can you advice on my situation?

i have a valliant combi eco tec plus.

I dont have a working thermostat. so does this mean the heating is juts on or off or? whats going on? pictures probably make more sense...

the dial with a radiator on the boiler, is that just a kind of minumum to max?

the connected honeywell device by wire that i'm holding up just has a binary on off switch on it, seems pointless?

the two honeywell thermostat looking devices seem inactive/broken/no battery/ not connected

how can i use the thermostat devices with temperatures on? should i? do they need to be directly wired? or should wireless? if wireless can i piut them in any room?

please see pics!

Y6630D Wireless Room Thermostat - Honeywell UK Heating Controls

 

[bob999]

thanks mate. so ive stuck batteries in "hcw80" the wireless rf, but it seems dead, following this video:
Binding the Y6630D Wireless Room Thermostat - Honeywell UK Heating Controls

so i guess i need to order one of these, ideally second hand from somewhere

Honeywell Y6630D Spare Wireless Thermostat Only HCW80.

what i'm not sure of now then, is how the other mains powered thermostat t6360 fits into the picture, is this an optional extra? does this mean there is some zoning and i need 2 thermostat temperatures?

or maybe i trash it and get a Nest or Hive?

 

[Gasmk1]

you would need a 2nd generation nest, you can get a hive or a tado or another wireless stat thats internet connected

Boiler pressure is low.

Boiler pressure is low.

Good spot

Curious about that hard wired thermostat, should be obvious where that came from.

 

[Harvest Fields]

Boiler pressure is low.

That gauge means nothing On a Vaillant mate.

...yeah forgot the zero pressure datum on that thing is about seven o'clock.

Curious about that hard wired thermostat, should be obvious where that came from.

so there are 3 things in the pics and its the 3rd one:
1) The receiver - which is connected to the boiler and has light on (part of Binding the Y6630D Wireless Room Thermostat - Honeywell UK Heating Controls)

2) the wireless thermostats- which has the cover lifted off in the first pic. this also came with the link above, y6630D, but is broken.

So i get how those 2 work, if they worked!

3) then i have this, which need to be wired into mains somewhere it sounds, cant take a battery. if the wireless one above in (2) is working would i even need 3? seems a pain to find somewhere to wire in that has electric in wall anyway?

Boiler pressure is low.

it is low, and needs a top up but its working at the moment!

That stat isn't wired to the mains but straight to the boiler and was probably replaced by the wireless receiver.
