Hello everyone,
i'm new here and this is my first post.
i have a Trane Chiller (RTAD 085-180 (50Hz)), which gives a fault of : " Chilled water flow (Ent Wtr Temp) "
" Latched Fault - Manual Reset Required"

at the diagnostic manual, it says that the description of this fault is one of these:
1- Entering Water Temperature < leaving WT
2- No water flow
3- Defective EVP sensor

it also shows that the temperature of inlet Water in lower that the exit water!
i tried to check the evaporator temperature sensors; the exiting water temperature sensor gives the right reading, but the entering water temperature sensor gives a reading of 2.4 C more (which should not be the cause that the entering water temperature is lower than the exiting water temperature).

so,, any help, suggestions or diagnosis..

forgive my weak experience and language

your help is much appreciated
