C5 It was detected that the leaving water temperature of the evaporator is 3.6ºC below the
anti-freezing protection temperature at the moment when all thecompressors are turned
off. The auto reset should occur whenthe water temperature reaches 3.6°C above the
anti-freezing protection temperature.

Code Diagnostic Description of Problem
C6 It was detected that the leaving water temperature of the evaporator is 3.6ºC below the
anti-freezing protection temperature at the moment when one or more compressors are
turned on. The auto reset should occur when the water temperature reaches 3.6°C above
theanti-freezing protection temperature.
Remote
6B6 Evaporator Leaving Water Temperature is above 46ºC. This message will automatically
be erased when the leaving water temperature drops below 43ºC. This diagnostic has
thepurposeof protecting the evaporator fromdamage due to high water temperature
inside of it. The water pump should not operatewhile this diagnostic is active.
Local
384 Water flow in the evaporator was not detected by the contact of the flow switch. This
diagnostic will be automatically reset when the water flow is reestablished.
Remote
ED After the presenceof water flow was established inthe evaporator, a posterior lack of
water flow was detected by the flow switch.
Remote
DC Water flow in the condenser was not detected by the contact of the flow switch. This
diagnostic will be automatically reset when the water flow is reestablished.
Remote
F7 After thepresence of water flow was established inthe condenser, a posterior lack of
water flow was detected by the flow switch.
Remote
F5 The high-pressureswitchwas kept open for more than 3 seconds. Local
FD The controller received asignal to turn off the equipment fromthe Emergency Stop
module.
Local
A1 Temperature sensor has a defect or a bad contact on the connection cable of the
sensors.
Remote
1AD The controller detected an error in its non-volatile memory and reformatted it. The
configurations of the controller should be checked.
Remote
2,00E+06 An operational failure of the controller's internal clock was detected. Check theclock's
battery and change if needed. This diagnostic will be automatically erased when the
clock is corrected.
Remote
1D1 It was detected that there was a failure in the storage on the compressors' number of
starts and number of hours in operation due to power loss. The data related to the last
24 hours most likely were lost.
Remote
1D2 An error was detected on oneof the controller's non-volatile memory block. Check the
configurations of the controller.
6B6 The compressor's counter of number of starts and number of hours in operation was
modified by TechView. The diagnostic will indicate to which compressor belongs the
modified counter. This message is immediately reset and will only be able to be viewed
in the log of diagnostics.
