Zones not working independently anymore
can someone please with my tado system, ive had nothing but issues with it since day one but now its almost impossible to use.
Its quite along story so appreciate anyone who takes the time to read it and offer advice as i am getting pretty much no help from customer support.
My system is as follows:
1x wired smart stat down stairs ( zone 1) with no smart trvs installed in this zone.
1x wired smart stat upstairs (zone 2) with 3x smart trvs in different rooms on this floor (no smart trv installed in the master bedroom where the room stat is installed)
1x extension kit for the hot water.
When i first installed the system, i could independently control each zone and the hot water was on a smart schedule, however the smart trvs were not assigned to any zone so would only really work when the main smart stat was switched on and the 2 way valve was opened.
I contacted customer support and they correctly assigned the smart trvs to zone 2 so that each room could call for heat as required ( or so i was led to believe this was how it would work) I was away with work when this change was made so never actually had a chance to test if it was working 100% but the wife seemed to think it was working better.
I came back from work a couple weeks later and noticed that despite having the smart schedule set up for each zone, the only way i could get zone 2 to heat up was to also turn up the heat on the stat for zone 1, this seemed to get 5he heat moving around the bedrooms in zone 2.
I again contacted customer support and got the following response:
From the information you have provided, we understand that you have a heating system as described in the 2nd option in this Help Center article. The Wireless Receiver/Extension Kit controls the central heating boiler (and, in some cases, hot water). On each floor, there is a wired Smart Thermostat controlling a heating zone. In addition, the radiators are equipped with Smart Radiator Thermostats.
In such a case, your radiators will only get heated when both the Smart Thermostat of that heating zone and the Wireless Receiver/Extension Kit call for heat. This means that in your tado° system, the Smart Radiator Thermostats have to ask for heat from both the Smart Thermostat and the Wireless Receiver/Extension Kit.
The Smart Radiator Thermostat, however, is designed to only ask a single tado° device for heat. It can’t, unfortunately, inform both these devices. As a result, the radiators with the Smart Radiator Thermostats might not receive heat when asking for it. Therefore, tado° can’t replace all devices in your setup.
You can still use tado° Smart Thermostats with the Smart Radiator Thermostats for individual room control. We recommend that you reinstall your old programmer and not use the Wireless Receiver/Extension Kit. If you had bought the Wireless Receiver/Extension Kit from the tado° webshop in the last 30 days, we’re happy to provide you with a free return voucher.
We’re sorry for the inconvenience and thank you for your patience.
So that has left me all abit confused as i know for a fact that before the smart trvs were assigned to zones, i could control each zone without having to have the other zone switched on.
I have been onto my tado app and can see that now each smart stat is set to have the extension kit as its zone controller, and none of the smart trvs are assigned to any zone, it also does not give me an option to assign smart stat as zone controller to each trv, the only thing it will let me assign is the extension kit.
I have looked at zone controllers on the tado site and found it is possible to have a wired smart stat set up as a wireless smart stat and on a wireless stat it is not possible to use it as zone controller due to it not been connected to the system valves, and it is possible to to reinstall the stats as a wired device instead on the app.
The story continues as i have came home today to find that it isnot possible to switch on the heating upstairs at all even when i set downstairs stat to heat up as i was doing previously, the only way i can get it to heat up is to manually open the two way valve and leave it like that until its heated up then manually close it again. And also the smart trvs are now overheating past the temperature they are set at.
Anyways if youve read this far iappreciate it and really just need some advice as to how to correct this as i when i specced the system tado confirmed that all these parts were compatible and should work fine, and now i, been told to remove the extension kit which is really jaut pissing me off.
thanks in advance
