Setting of proportional cooling band
Index - String
MIN
value
MAX
value
Parameter function
1°C 20°C
This parameter indicates the proportional band applied to the cooling set; this band
produces the optimised management of the compressor, only switching it on if the inlet/
outlet water temperature (depending on the type of control set by parameter (0) in the
installer menu) is greater than the cooling work set (parameter (1) user menu) plus the
value of this parameter.

25°C (*)
This parameter indicates the value of the work setting active in heating mode. In cooling
only units, this parameter is displayed but it cannot be modified.
(*) the maximum limit can be configured by means of the parameter (t) of the installer
menu
