We just had a new Lennox G61MPV/XC14 along with a PureAir and an HRV installed during a big remodel. Brand new main trunking was installed and split to accomodate two zones. Existing vertical ducts to rooms were kept.
1) Finished Basement (~1200 sq ft) and
2) Main/2nd floor (~1800 sq ft)
Both trunks are 6"x16" and accessible. We just have one main t-stat installed now (main floor) which is a Honeywell TH6000.
We have a quote that seems quite high for configuring 2-zones. There is no parts list so I don't know what they would use.
I am thinking that 2 dampers, a zone controller and a second t-stat is all that is required along with a bit of wire. Is this a DIY job?
