Controller temperature logic is not start chiller

Hello All,

Today after more than one and half year of operation I faced huge problem. My chiller was not started and temperature was raised to 32C. I did not change any setting a lot of time. What I have:
Computer: Profilux 3.1N ex
Chiller: Profilux Propeller Breeze
Temperature sensor: Profilux probe
firmware version: 6.06

Setting in socket function: S3 "Temperature 1" "Chiller". Temperature max deviation +-1,2. Target temperature 26C, Current 30 and chiller was not started in this situation.
If I setting up "Always On", Profilux Propeller Breeze is working properly.

What happened? Did anyone face this situation?

Thank you!
Vadim

Does the temp sensor still show the correct temperature?
Has the LED lamp been on or off at the socket in which the breezer should have been on?

For testing you could also try another socket.
