C.Fo5 C.Fos Pfa Means, thermostat probe is broken. P5C Means, thermostat probe is short circuit. Temperature value is higher than the scale. Temperature value is lower than the scale. ALARM SITUATION -24..When the alarm situation occured, the measured value flashes in the indicator and if Snd parameter is not is given audible alarm by the device. While there are a audible warning ; key is pressed, the audible warning will be disabled. EA 2.External alarm is activated but output s is not affected by this situation. 3.Except that the alarm has been activated and external alarm output relay is active when the show shut down. (off situation). 5A 4.Buzzer voice warning is given;if any key is pressed the buzzer will be silenced. HOW CAN WE RETURN THE DEVICE TO THE FACTORY TINGS Key is held down while the device is powered up the d.par message will see and restore the factory parameters. 2/6 EDT242-E-2-24
