thank you all for your support
I shall go ahead and connect wire 2 & 3 and isolate wire 5 to decommission PRT2 thermostat and keep it active and controlled by tado smart wireless thermostat as per tado guidance for decommissioning purpose (minute 1:24)
@stem sorry to bring you here but seems you had the previous version installed of tado wired stat over PRT2
You may have idea on how I can make PRT2 on by connecting the wires
The number 2 and 3 I mentioned earlier was related to PRT2 thermostat
Do you believe if I connect 2 and 3 and leave 5 isolated would make the thermostat on permanently?
When I replace it potterton programmer with tado wireless receiver I followed tado Y plan as per picture attached. And I see from Potterton programmer CH NO is yellow.
Should I safely assume to connect yellow wire (3) with red wire (2) will make it permanently opened?
Dear DIY, Professionals
First let me wish you all a happy new year
Despite of 100s of posts about Potterton wiring but here I am got a bit lost here about how to decommission PRT2 the way how Tado posted on their YouTube link.
Basically after I finished installing the receiver next to boiler...
Hi B,
I am happy for you you made it through now it is my turn and seems mine is more complicated as there are more wires connected.
Do you happen to have or remember how did you manage to wire tado?
