Hi , I have a new (installed 8 months ago) Carrier heat/cooling 2 zone infinity
control system . I keep having issues with it shutting off for static pressure
when it is running one zone . When I watch the system if both zones are on
static pressure is about 1.1 , when it goes to one zone it goes up to 1.34 then starts to read "unknown" and will shut off after that . Any ideas ? The contractor who did the job said I needed more ducting in the zone , which they did but I am still having the same issue . I tried calling Carrier's 800 number but the do not provide tech support ! Any help would be great.
I live in San Jose Ca , if anyone can recommend someone who knows about
these units it would be a big help !
