Vailliant ecoTEC 831 with VR61 and zone valves?

Hello all,

I have a Vailliant ecoTEC 831 controlling two heating zone’s through a VR61 with two thermostats one VR81 and a wireless RC470f controller, with thermostatic radiator valves.

I am looking at the V3+ starter kit with radiator valves to replace the controls and give more flexible control over times etc.

Is anybody able to advise if I can retain the VR61 by using the EBUS wiring and possibly the VR81 to control the zones along with the Tado or is it better to remove the current controls and use all the Tado ones?
