Extending a Multi Zone System
I have installed a Tado system in my home and would like to extend my system.
My current set up is :-
A three zone system with one valve controlling the hot water
A second valve controls the downstairs central heating
A third valve controls the upper floor central heating.
The down stairs central heating system has a wireless thermostat and 6 smart TRV radiator thermostats allowing independent control of almost all radiators downstairs. In addition to that we have an internet bridge that is connected to the home router via a TP Link powerline network extender. In the utility next to the boiler we have a Tado Wireless receiver (programmer).
Upstairs the heating is controlled by a single wired Tado thermostat. This thermostat activates the control valve and heats all radiators upstairs.
I am thinking that we could improve the system by adding another set of smart TRV radiator thermostats upstairs. I would like to control 5 radiators upstairs and still maintain the two zone status. However, I do not see how the system would know how to select only the upstairs control valve.
Can you please advise if it is possible to control individual radiators upstairs (within their own zone)?
If it is possible to control individual radiators upstairs can you please recommend the additional equipment we would need?
