Carrier 30hwa chiller a207 fault
Alohas everyone,
every night our chiller will fault out with a A207 freeze protection fault. Could this be a flow problem? I noticed LWT temp 44.5 degrees and EWT temp 45 degrees. It only happens at night so should I be looking for a air handler flow valve changing flow rate? I am a newbie to AC so please excuse me if this sounds like a dumb question. Glenn

Welcome Glenns.
My first question is what is the freeze stat setting?
I asume it is a programmable set point that can be altered?
Following on from this could it be faulty?
