How to change the master-slave control model
 
The HVAC control system in my house follows the master-slave model. I would like to change it and make all 3 zones completely independent.

How should I do? Will this would be a big project?

Thanks a lot

Would need brand and model number of the zoning system, and the thermostats.

The model number of the zoning system is: EWC controls INC. Model: EWC-ST-3D ultra-zone control panel

The mudel number of the thermostats is: Braeburn system, model: 5000

Sorry, not familiar with that model.

Any idea what should I do to find out? Like where to find the contractor?

Will this be covered by the home appliance insurance?

Probably won't be covered, since its working. Warranty usually only covers things that don't work.

May want to contact EWC, and ask them if it can be changed, and find out if they can send you the install manual for that panel.

As Beenthere has posted an alternate EWC control would be the least expensive solution because of the cost of new damper installation.

The new Ultrazone 4 looks like it will give you independent control.
