Can't add thermostat or Extender
i have a vaillant ecotec 630 with vr65
Due to logistics, availability timings & cost i purchased my Tado kit from 3 vendors.
V3 dual Radiator starter kit from argos
thermostat and extender from amazon
9 x radiator stats (incloming) from Currys
i connected the 2 x radiator stats and internet bridge from argos first as they arrived first and had no issues.
i then had the extender added to the vr65 ebus and added the thermostat and extender to my account via the iso app. after pairing and seeing connected i'm then told to complete the process in a browser. at this point i can't proceed as there is an error
"there is a Room Unit without a zone, though Boiler Unit is registered for installation process SALE_FITTING_ST_G1.1 - INSTALLER_INSTALLATION_PENDING (discr: 0) of home"
What needs to happen now?
