Mixed System with UFH - Wiring to Manifold
My plumber is in the process of installing Tado for my new heating system, which consists of:
- Boiler (Vaillant ecoTEC plus 630)
- Megaflo/Hot Water Cylinder
- Radiators for the loft and first floor
- 3x Wet Underfloor Heating zones for the hall, kitchen/diner and utility/bathroom
I was told by Tado support that my system is compatible and that I would need a starter kit with an extension kit to manage the radiators/hot water, and 3x add-on thermostats to manage the seperate UFH zones.
Am I right in thinking that the thermostats controlling the UFH need only to be hard wired to the manifold to control the actuators/zone valves for the three seperate zones, but then this is the only wiring required? Hence the hot water/boiler will be turned on when needed through the wireless connection between the three UFH thermostats and the extension kit?
I've looked through the manuals but I can't find any wiring diagrams in regards to underfloor heating - can someone point me in the right direction please?
Thanks in advance!
