Hi,

We are going through our first hours with a Climatemaster TT064 Packaged Unit (vertical closed loop, 3x300), and Honeywell VisionPro TH8321U1006 thermostat.

Initial checks (at 15 min running) seem quite good. The unit started with indoor air at 78 and set to 70, immediately went to stage 2. EWT/LWT were 64/73 approx, and the delta temp on air was around 20-25 degrees F.
The area cooled went to temp within about an hour or two.

Watching things as they run, I have a few questions. It appears that when the unit cycles back on to deal with cooling, it always goes straight to stage 2.... Y1 and Y2 LEDs are lit and the CFM led flashes 21 times indicating approx 2100CFM (where it was set for stage 2).

Can someone tell me how to confirm this is operating correctly? Shouldn't stage 1 always be the starting point? and how is stage 2 controlled on these units? by the thermostat? if so, where on the thermostat is the setting that controls when stage 2 should happen in cooling?


Also, when the unit was off (reached temp).... we noticed that the display indicated 72 inside temperature, and set-to temp was 70, at which time the system kicked back on...... our old thermostat seems to have caused the system to start much sooner than a 2-degree differential. Is that something configurable? (I did check the install setting on the t-stat and it is set to display accurate temperature...) is there a setting that initiates Stage 1 when the temp goes higher by some amount that is configurable?

thoughts?

Daniel,
I don't think we can restore your lost confidence in your installer. Please contact Climatemaster and ask for a represenative to evaluate the work of their dealer. All dealers go through a cursory training program, they (Climatemaster) would like to know about it if your guy did not absorb his training.
Nor can we from afar properly evaluate every detail of your equipment operation.
Good luck!
Joe

Thanks for help.
I never intended to take money away from a true professional; I thought this site was more geared to helping/learning than that other one that throws DIY in your face every time a question is asked, and I guess that you don't know whether or not I did contact Climatemaster (which i did, and am awaiting their tech rep to check things out......)

I suppose that 1) you have no idea of my ability or background...(which is significantly higher than a high-school education),  so I instantly must be an idiot that is either too stupid to understand a reasonable response to a question, or for hiring a contractor that is new to this and 2) I didn't have my wife ask the question.


And to the one person that did respond privately to previous questions.... thank you! you demonstrate true ethical and moral values are..... helping someone learn....


Sorry for taking up your bandwidth......and disk space....and time.

Daniel,
I'm sorry if my suggestion to contact the manufacturer with questions was offensive. You seem to have a large number of concerns and a lack of confidence in your installer evidenced by the number of threads you have posted. I hoped to offer you a reasonable avenue of support as both your latest threads were un responded to. I'm not sure what that has to do with money, professionalism or the gender of the question writer, but I can tell you we had our first <40 degree weather here and with unprecedented demand manufacturers' are running out of all sizes and types of heat pumps. Combine that with the hours you see my posts and perhaps you'll concede the point that I'm trying to be helpful.
The manufacturer of any product is your best ally when your satisfaction is threatened. As you've made it clear that you haven't trusted your installer and are unsure as to the installation or application, I think seeking a qualified installer was good advice and in it's stead contacting the people who sold it to an unqualified person is the next best thing.
I wish you well,
J
