TP9000, TS2 and TP4000 replacing with Tado
My Existing setup:
TP9000 in utility attached to Ideal Logic+ Heat 15 combi boiler. TS2 sensor in dining space. TP4000 in Master Bedroom upstairs.
I wish to get multizone heating setup with:
Tado Smart hot water control unit replacing TP9000, getting rid of TS2 sensor as will be using Tado wireless thermostat. Wish to keep TP4000 wired unit as it is (Ques: is it possible?)
putting Tado smart radiator controls on 6 radiators across 2 floors for multizone setup.
I am bit confused on the wiring as my existing TP9000 wiring seems bit different from what I have seen in forums. I have wires attached to port 1 and 3 as well which I am not sure what to do. I understand 5,6 are TS2 wires and need to be put off taped.
My wiring diagram is below:
Any help is much appreciated!
