    techno trans error c circuit anti freeze device, two flow sensors are working and 3 temp probes are working , all water levels are filled and the fans and condenser are clean . this error won't let the compressors turn on.

    Hi,
    Test this:

    Refrigeration Unit

    Refrigeration unit not running or reduced refrigeration capacity

    • Condenser cooling fins dirty
    • Condenser ventilator defective (motor coil overheat
    Insufficient chilling medium supply
    • High pressure fault

    T-circuit

    • T-pump not running • Reset circuit breaker

    • Valves closed
    • Not enough pressure
    • Low water level
    • Fill up water, press
    • Fault on refrigeration
    unit
    • Setpoint temperature
    too high
    • Safety temperature cutoff
    inside heater tripped
    • Setpoint temperature
    too low
    • Leaks in system

    Is there any ice formation? If the error comes on immediately after a restart or does not let the compressor to run at all you are likely looking at a faulty temperature sensor for the C circuit.

    The dampening water is cooled indirectly, the gas cools water inside the C circuit and that water then cools the dampening water through a different heat exchanger.

    Make sure there is water inside the T circuit also.

    Hello, Refrigeration gas is correct,no leaks sometimes the Refrigeration will come on for a second then shut off and the C circuit error pops up, Could the touch screen controller be bad, When setting temp limits the numbers go corrupt. This unit is a Tre40-Tcp40

    Hello, you won't believe this, Problem solved, First the temp limit numbers were corrupt, I put a new battery in and it works perfectly now. The compressor would come on then shut off saying low pressure, the freon was at proper spec. The modulating refrigeration valve/solenoid wasn't opening the valve to let freon flow, the solenoid is bad. We manually opened the valve just enough, now it works great cycling between the 2 compressors chilling at proper temp setting. The controller was 10,000 dollars new fixed with a 5 dollar battery.
