Hi all
This is my first post here. So I hope I get it all right first time.
I have a Bungalow with an existing heating system which I now want to upgrade with a Vaillant EcoTec 624 boiler and Unistor 210.
I have 6 Radiators and 2 Zones with underfloor heating.
I will have to manifolds 1 for the underfloor heating and one for the radiators. Both manifolds will be coupled via a Thermo device that will have a flow temp in the radiator manifold of 75 and on the floorheating manifold of 45 degree celsius.
My main question is the technical parts I need from Vaillant to control all parts.
My idea is to use a VRC430f VR65 VR61 and VR81
I want the 430f to control one of the underfloor heating zones, the VR81 the other underfloor zone. The other rooms don't need a controller as they have electronic valves on the radiators. The VR65 is just the control unit for all other parts.
The VR61 is a bit of a puzzle.
I hope I get this right. If I understand this correct I should be able to control the Unistor 210 and 2 other zones (the underfloor ones) with this unit in conjunction with the 430 f and VR81. Point being on the manifold for the underfloor heating I have electric valves that will open and close if 230V are being switched or not.
Is this right???
Hope someone understands what I have written and can answer me.
Thx Ian
