To increase / decrease the power the compressor works by step of 1% of the power; every step is delayed
by CO62 at the start-up of the compressor and CO71 when the compressor works normally.
When the compressor inverter controlled is activated, it works at power configured by CO61 parameter for
CO60 seconds; after that:
if the parameter CO62=0 the compressor modulates the power according to the regulation request
the parameter CO62
0 the compressor is forced to works at maximum power and then it modulates
the power according to the regulation request
It is possible to limit the output % of the inverter compressor in Chiller, Heat pump and Sanitary hot water:
o
maximum % output inverter in Chiller (parameter CO79)
o
maximum % output inverter in Heat pump (parameter CO80)
o
maximum % output inverter in Sanitary hot water (parameter CO81)
COMPRESSOR INVERTER CONTROLLED OPERATING MODE: CHILLER
At the start up the compressor is forced to work at CO61 speed for CO60 seconds.
COMPRESSOR INVERTER CONTROLLED OPERATING MODE: HEAT PUMP
At the start up the compressor is forced to work at CO61 speed for CO60 seconds.
