External secondary probe
The electronic board have the optional of secondary probe. This is possible to use this is probe for measured
the environmental temperature. The external probe being an optional is on default disable, after the
installation on this is optional is possible to able the probe.
Temperature differential
This is option make the possibility to set a differential value on the temperature control system. The
differential induces on the difference between the temperature measured and the setting temperature.
When the difference of two temperature is the same differential value the compressor turn on. The range is
a value to 0,5 from 3.
Probe calibration
This is option have the task to correct the probe temperature value respect real ambient temperature. The
calibration is a value that have the range from – 5 °C to 5 °C. The value of calibration is added or taken out at
the probe temperature.
System operation in case of faulty probe
In the case of the probe is damaged, the air condition system keeps running but with a running times and
