Awl --
For the MSZ-FD12NA, 12,000 btus.
The estimator told me these are 120 V units, but the literature says these
are 208-230. In addition, the RLA is 8.6 amps, which seems kind of high, at
230 V.
My 5 ton old-technology unit outside draws only 19A at 240 V, according to
an amp-probe. In proportion, this is a much greater efficiency.
I thought the current draw of these inverter units would be much lower.
Next, at low-load, by how much does current draw modulate on these inverter
units? 50% of RLA? With a proportionate drop in btu's?
Finally, the literature list an LRA of 10.8 A.
That, in comparison, seems very low, as most motors I've dealt with have an
LRA of several TIMES the RLA rating.
Iny idears?
