Honeywell RedLink

January 26, 2012 Leave a comment

I finally finalized the spec of the HVAC system today and placed the order. It only took 11 months and discussions with 5 different suppliers to get a sensible proposal. The final system has six zones, all individually controllable  consisting of three wall-mount units like this:Mr Slim Wall Mount

and three mini ducted units in drop ceilings like this:

connected to a single outdoor compressor like this:

But the really clever bit is that the latest units are Honeywell RedLink enabled. RedLink is a proprietary Honeywell wireless protocol. Every unit communicates wirelessly over RedLink to an internet gateway that plugs into the back of your router like this:

You can control the units from the Honeywell Total Connect Comfort website or from an app on an iPhone or iPad:

and the good thing is that the price is quite reasonable. The gateway is only $100 or so versus the over $1000 commercial solution that was originally proposed. The fact that this system is wireless rather than wired makes installation cost lower too.
All the latest Mitsubshi indoor units are RedLink -enabled which means they talk to the Honeywell gateway. There are also other accessories you can get like an Outdoor air temperature sensor. And I guess the range may be extended later.

RedLink is a new system for Mitsubishi which they appear to have licensed from Honeywell. It’s only available in March this year from Mitsubishi so I will be one of the first. Let’s hope it works OK. It seems more consumer-friendly than the previous rather industrial system Mitsubishi had, which was mainly aimed at owners of large commercial buildings.

Sub-roofing material arrived this morning. 6600 sqr ft of plywood on that truck plus some LVLs (Laminated Veneer Lumber) which is like structural plywood.

Slight problem with the facia

Oh dear, the house and the garage are supposed to be the same height and the roof seamlessly transition from one to the other. But it seems there is about an inch difference in height! Need to figure out a way to disguise it, but it isn’t simple, when you change something you just move the problem some place else…

House is to the left, garage to the right. Roof supposed to be seamless across the two. Hmm…..

Otherwise progress goes well, we hope to get the roof on this week, except for the two story part.

I I like my big roof overhangs, it will keep the house in the shade in the summer and hence cooler.

This is where the pool will be, it should be nice and shady.
