Hi Avsuku,
I believe that you have an RTWA213 or RTAA213 chiller.
Both alarms can be connected to programming of the unit due to compressor module(s) replacement or the main controller (A1) have lost the programming for a reason or have been replaced.
In each case please let us know correct model number, type of refrigerant, method of starting (Star-delta, part winding, X-Line) and if these alarms are for both circuits.
Also let us know if the compressor modules or main module have been replaced and if you have already checked the programming of the main module.
A good advice is to start a new Thread to COMMERCIAL or TROUBLE SHOOTING.
Regards,
