24.1 Inverter Compressor In Heat Pump And External Temperature
It is possible to reduce the compressor speed (both compressor in parallel if configured) in heat pump when
external temperature increases over a determined temperature.
25. COMPRESSOR RACK
The IC200L can manage a compressor rack; the configuration parameters are Cr01…Cr09.
In this operation mode the controller can manage maximum 6 compressors in only one circuit; only the chiller
mode is enabled and the regulation is only in proportional mode.
The parameter Cr01 allows to enable the compressor rack regulation:
Cr01 = 0
Compressor rack regulation disabled
Cr01 = 1
Compressor rack enabled and regulation on the probe defined by parameter ST09
Cr01 = 2
Compressor rack enabled and regulation on the evaporator trasducer
It is possible to choose the number of compressors the controller can use in case of regulation faulty probe;
the parameter involved is Cr08.
It is possible to choose the number of condenser fan steps the controller can use in case of faulty probe; the
parameter involved is Cr09.
The Energy Saving function, in case of compressor rack unit, has dedicated set point and differential
(parameter Cr06 = “Energy saving offset for compressor rack unit”, Cr07 = “Energy saving differential for
compressor rack unit”)
