I have a 5 star rating refrigerated cooling, which comes with 2 zones.
I've upgraded an extra zone($450), where I was told we will need at least 3 vents in each zone, so I've added an extra vent to my master bedroom ($160), to have a zone in Master/ home theatre.
That happened after the electrical appointment in Sept and I have signed the variation a week after. However, I cannot see it in the final plan that they are building off. I can only see a vent in master and a vent in the home theatre. I have tried to contact my liaison and SS.
liaison said: 'I will pass that to the suppliers'??!?? Why?
SS said: 'you can switch on and off, not a problem.' (complete dodged the questions about the extra vent and zoning.)
So do I need 3 vents in each zone?
I wanted to but I did not because I was led to believe that the system I was getting could not cater to the additional zone and I would need to upgrade the system at a much higher cost than your $ 450. My pre-start spoke to us about our need for 3 zones and at the end of the day, managed to convince us that we did not really need the 3rd zone.
