Probably go for Warmup 3IE stats, or similar - room stat in unit + floor stat

Does anyone have any suggetsions on which gear would be best for this arrangement. Need to use a solar switch to feed an immersion heater and 3 zones of UFH. Outline attached. Feed from the solar switch needs to be routed to the UFH zones or the immersion heater - controlled from a room...
