Functioning with Probe 4 within the LAN:
Functioning Without Probe 4:
In this case, regulation is performed by switching the auxiliary relay ON and OFF on a 60-minutes time base. The ON time will be
the AMt value, so that the relay will be ON for AMt minutes and OFF for [60-AMt] minutes.
In case of P4 error or if P4 is absent, the output is at AMA value for the AMt time then the output is at 0 value for the time
[255 - AMt] time performing a simple PWM modulation.
12.9. Cleaning Mode Function by Digital Input Configuration
The “cLn” value is added to the functions of the digital input.
The function has the same basic features of the stand by function, but with the following differences:
a. By the parameter LcL (No, Yes) it is possible to set if the light is on or off during cleaning mode. This parameter LcL can
be override by light button or by Light on/off MODBUS command.
b. By the parameter FcL (No, Yes) it is possible to set if the fan is on or off during cleaning mode. In case of fan on, the FSt
parameter (fan stop temperature) is override.
12.9.1. Display
During the Cleaning Status, the display shows the “cLn” message.
12.10. Auxiliary Output
The auxiliary output is switched ON and OFF by means of the corresponding digital input or by pressing and releasing the down
arrow key.
