Yes, there are two zone valves near the boiler (I don't know how many ports) and a thermostat strapped to side of the hot water cylinder. 2007 110 TDCi Station Wagon XS

Sako243 have you tried those WiFi extenders? I have heard they work great and use your wiring throughout the house as an aerial. So I have been told
 got to be with a try I think they are quite cheap too 2023 Defender L663 V8

Bluest, then you have a fully pumped system, I’m a nest fan and have fitted many and even have one myself. What you have should work well with either of the wireless units. Your electrics should all be there. You probably have the cream coloured Honeywell programmer? Some of these models have a switch or little links to link the hot water with the heating (used for gravity systems) and this sometime got overlooked when installing, if you have the earlier one there’s a little slot on the slider to untether it from the heating slider. 2023 Defender L663 V8

Thanks Bear. The Honeywell sliders are untethered 👍
If I were to go ahead, I think I would be forced to have the Hive, as there is no power near to where I would want the thermostat. I believe the Nest stat needs a USB power supply. One last question on the Hive. What sort of range do they work over? My boiler is probable about 15m from where I’d site the ‘stat, through three block walls. Will the signal reach? 2007 110 TDCi Station Wagon XS |

No worries, you can install the nest anywhere, it doesn't have to be connected to your stat wires but it will need to be plugged into a power socket, ideal if your using the stand

It’s just there will be hole in a tiled wall when I remove the old stat, so I need to stick any replacement over that. 2007 110 TDCi Station Wagon XS

Sorry to resurrect an old discussion, but I have a couple of questions on Hive controllers that I am hoping someone can answer !!
Just ordered a two channel Hive kit to use on our heating system. I ordered the Hive version that supports "Tanked" hot water. Our set up is an old one with an indirect water cylinder heated by the same boiler water that does the central heating (CH) circuit. The current controller allows me to select hot water (HW) only or hot water and central heating. No valves or pumps for the HW coil. It just uses thermal action to circulate the boiler water through the heating coil in the hot water cylinder. When the controller calls for HW only, it provides a 240v live output to the boiler which triggers the burner. The boiler temperature is controlled by the boiler stat which regulates the burner. When the controller calls for HW/CH, the HW and CH outputs are both live. The HW live triggers the boiler as above. The CH live provides a feed to the CH circulation pump via a room thermostat. Once the room is up to temperature, the circulation pump stops. Again the boiler stat controls the overall water temp in the boiler and regulates the burner as needed. The boiler has a separate permanently Live/Neutral/Earth fused feed which allows the boiler to run a post purge cycle once the controller shuts down the boiler. I am assuming this feed also drives the blower motor and internal ignition circuits, taking current load off the controller switching. Long intro, but here's the questions : With the above set up, am I correct in assuming that the Hive 2 channel controller HW & CH N/O terminals will provide the same switching? And that I won't need to use the N/C terminals on the Hive backplate. Because the Hive thermostat will be controlling the CH room temperature, I am also assuming the CH circulation pump will be wired directly to the Hive CH N/O terminal, with the Hive thermostat controlling the switching of that terminal. Is this assumption correct? (With the pump also connected to a Neutral and Earth). The old 2 wire wall thermostat and wiring will be redundant. I realise from the installation instructions that I will need to configure the Hive for a gravity feed system. Hope the above makes sense and any feedback would be a big help before I install it. Cheers. Edit with update : All sorted. As I suspected, the two N/C terminals on the Hive backplate weren't needed. Boiler start/HW only, triggered on the Hive HW N/O terminal. CH Pump triggered on the Hive CH N/O terminal. |

I finally got around to fitting a Hive. Was very straightforward in the end. Hardest bit was identifying and bridging the ‘stat wires, which wasn’t actually very hard (although I am colourblind
 ). Everything else was just a case of swapping the wiring like-for-like. The Hive comes with pretty decent fitting instructions. 2007 110 TDCi Station Wagon XS |
