6 - START-UP
It is possible to limit the absorbed electric power with an external signal of 10 Vcc or 4-20 mA. The higher the signal is, the lower the
number of compressors available to meet the thermal need .
The parameter configuration is necessary.

It allows the automatic correction of the set-point, according to an
external signal of 4-20 mA or 0-10 vcc.
The working process is similar to the above mentioned process .

It allows the automatic correction of the set-point according to the
external air temperature.
For example, the summertime with low external temperatures, it is
possible to have the internal comfort even with set-points higher
than the standard. The parameter configuration is necessary.
