T-Stat Integration

Man with a question

Greetings,

I have been asked to integrate all the t-stats in a project to 1 or 2 locations with only 1 device to control numerous t-stats.

This home has the following:

6) Heat/Cool Zones via heat pumps
4) Radiant Heat Zones

What I would like to do is to install these 10 t-stats or temp sensors in a remote locations and have the homeowner be able to adjust each zone from a single device.

What is out there that my customer will actually understand without me having to spend six Sundays explaining it to him?

I originally set the house up with remote temp sensors run to banks of t-stats in 2 inconspicuous locations, but the "Designer" has nixed this plan. She wants a single device or perhaps 2 devices (upstairs/downstairs) only that the homeowner will actually touch.

What say ye?
