Ok, I ran a call today; the walk in temp was 50 deg.
Frozen coil! I looked to check the TXV and I didn’t
see one in the evap.
I now understand the entire rack system is controled
by an XDX controler system.
With zero Info on this cold zone rack system, I now seek
any and all Info on this system.
I can not stand being In the dark on something like this.
I will visit the cold zone web site and, check
other search engines.
But I would like any info you guys could come up with.
