I currently have a NEST(in the house we are renting). I plan to install a combi boiler for instant HW, combined with something like EvoHome to have zoning without needing to re run all pipes. Do you know if EvoHome deals with combi boilers? It has to be simple and maintenance free.

deezell wrote: » The ext kit has two relays, one for wireless connection of the Tado thermostat, and the other for controlling the timing of HW, so you get both in the one box. The Tado thermostat on its own has a built in relay, so it can be wired directly in place of an old thermostat, and you can continue to time your HW with the older controller. If you buy the extension kit later or as part of the starter kit with HW, you can use the wireless feature optionally, but in your case it will directly replace the old controller, wired in its place. The old CH stat can be removed and replaced by the new stat wired in, or wirelessly connected. The old HW stat remains in place, the Tado only controls timing of HW, not temperature. Rad stats (TRVs) are not that expensive, €45-60 depending on special offers, but will require the fitting of a TRV type valve body on each rad if you don't already have manual TRVs on them.
deezell wrote: » You need to associate the stat relay for the zone the TRV is in to the TRV room. On the App,Settings/Rooms and Devices/{TRV Room Name}/Zone Controller. On this page, choose the stat/device which calls the correct zone for that TRV. You should have a choice of two stats, or possibly one stat and the ext kit, there have been some logical changes to this since I last looked. Remember, a single TRV will call the entire zone when it calls for heat, so its mostly used for colder rooms which 'fall behind' the main zone stat setting, or to turn off unused rooms during a general zone call.
salnado wrote: » That worked perfectly. Everything seems to be working as it should. Thank you for the help, it was invaluable. I have one final question. I also bought two Tado TRVs. I installed one on a radiator on the downstairs circuit (spare bedroom) and one on the upstairs circuit (in a different room to where the thermostat is). In the Tado app I have set each of those up as individual rooms. If I want them to successfully call for heat, even if the main thermostats on those circuits aren't, what do I need to do, I can't find any setting for that in the app?

L, N, and there should be no more than three live outs to the wall/cylinder stats, and then on to the valves, which in turn collectively though their built in relays will fire the boiler when any of them open. The ext kit will replace the EPH locally for timing of HW and CH1. CH2 is first wired in the tado to L, which is always on, but then replacing CH2 stat with a wired tado stat controls the live to the CH2 valve. The timing as well as the temperature control all take placs inside the Tado stat. This is the key difference. Traditional system has a timer controller, with these timed lives then sent to a wall stat or cylinder stat for temperature control. This is combined in the Tado stats, whither wired in, or wireless via the ext kit. Only the HW retains its mechanical stat, with the ext kit supplying the HW timed live

( i was on 5ghz ,) once i changed to 2.4 it was easy.

digiman wrote: » I managed to get the Honeywell Evohome setup to control my hot water, upstairs and downstairs myself. Very happy with it so far, 2 issues left to fix though. I need to replace the existing radiator valves so that they will be able to take the fitting for the Honeywell Thermostats. Is this a job that one could do himself, I ain't no plumber, have just watched a few youtube videos where guys have frooze the incoming water supply and seal off the flow in the other direction for long enough to swap the valve. Have a very stupid question coming up, I've an unvented hot water tank so I need to use the insertion sensor. I'm not clear though where exactly that is supposed to go though and how do I get it inside the watertank. Do I need some other parts, obviously wondering how does one get this into the tank without flooding the house!

From the EPH website I need a gateway and a couple of thermostats (one upstairs and one downstairs). You can purchase complete kits (that include the controller I already have), but I cannot find any where else online to purchase thermostats separately. I found the gateway on Screwfix (for 100 Euro). Any one come across EPH thermostats separately online? Thanks!
salnado wrote: » From Live L of the Tado correct? That's input L of the Tado,correct? Am I right that in all this the EPH can be removed? This question is irrelevant if the EPH can be removed. If not then If CH2 is still going to input L of the EPH, do I need a feed to the Tado L and N? Do i just loop off the EPH to do that?

JohnDeereIE wrote: » Thank you I think the 1200 included the kit plus a number of rad thermostats so might not be too bad. At the moment it has two thermostats which are connected to an old controller. It turns on/off heating and water. You can turn on one without the other if you know what I mean. I was going to get the "tado° Wired Smart Thermostat Starter Kit V3+ - Intelligent heating control, easy DIY installation" but I don't see this starter kit with the hot ware controller. Or do I need to buy the "tado° Wireless Smart Thermostat Starter Kit V3+ with Hot Water Control " Do I get the Wired kit and then buy the hot water separate? Thanks again(Sorry can't post link)
salnado wrote: » Thanks Deezel. Attached is a better diagram with more detail including the EPH (which is a T37 - HW). Also, I found an installation manual for the boiler at this link Based on this further information, I think the existing setup is wired according to an S-plan setup. I will wait on Tado to come back to confirm what I should connect where on the Wireless Receiver.
deezell wrote: » You need the Tado starter kit with HW. This has a relay box known as the extension kit for timing of HW, but you still retain your wired hw stat. It also has a relay for wireless operation of the Tado stat, but the stat can also be wired in place of the old stat, with the ext kit only used for hw timing. You say you current system is two stats. Is there a timer also? can you heat HW only and CH only, or does HW heat when you have CH on? €1200 is mad alright. It might be easier to leave the HW alone, on its own stat (is this on the side of a HW cylinder?), and just get the wired Tado stat kit and replace the ch stat, a DIY job.
deezell wrote: » your existing wiring circuit is too vague to draw any real conclusions from, but if the controller is a standard 3 zone EPH, it should be possible to simply substitute the Tado as you suggest, with the ext kit replacing the outputs of HW and CH1, and a wired back connnection from the other Tado stat to trigger CH2. Try to establish if all zones are independent, with each operating only its own motorised valve. The boiler model you listed is proving difficult to find an installation wiring diagram for, but I assume it is fired by the combination of all three valve relays, possibly volt free. I note an orange and grey wire to what must be the boiler call terminals. I have only found this boiler model on US sites, installation in the US can be strange, volt free for firing, and odd connections for external valves, but I'd take it yours is a straight 2 pipe connection with s plan valves to the 3 zones, HW in a cylinder, not direct from the boiler. Also, the model of the EPH is T37 or R37? the HW designated models can have a gravity mode switch, using the HW output to fire the boiler for all events. Again the presence of three valves should indicate proper s plan wiring, hence the need to check for zone independence. A photo of the EPH backing plate wiring would be useful also. Its not clear from your diagram at what stage the zone thermostats are wired in series with the EPH live calls to the zone valves, but it should not make any difference, if you merely substitute the ext kit for the EPH, wiring CH 1 and HW in place of the first 2 EPH zones, then wiring EPH CH 2 to permanent live and replacing it's wired stat with the Tado. Also turn the old CH1 stat up full or else remove and cross its connections.

Went to a supplier and he wants 120 euro just to drive 10 mins over the road to look and says it will probably cost circa 1200 euro which is crazy. I was going to buy the equipment myself and a mate who is electrician said he would install. Am I correct this is the kit I need to buy? Tado Wired Heating Starter Kit Water Starter kit I can only seem to find the Water starter kit with the wireless but at the moment I have a wired existing thermostat. Or am I talking gibberish.
