In Ice mode, while the compressor loading is not affected, the compressors downloading is
inhibited. When downloading is required compressors are shutdown on the basis of the evaporator
leaving water temperature.
In particular, said Stp the evaporator leaving temperature setpoint, SDT the shutdown

T
value and n the number of compressors, the scheme in table 6 is used.
In addition when the heat pump option is installed, the compressor could be managed using
a variable speed driver (inverter). An analog output of pCO
3
board is used to control the compressor
speed with a 0-10V signal. Load management will still determine the time distance between
load/unload pulses where pulse in this case means relative variation of the output voltage. The
magnitude of the variation could be adjusted under manufacturer password.
When the unit is working in heating mode the maximum speed will be the nominal speed
(default value 67Hz).
When the unit is working in cooling mode an overboost option (activated either with the digital
input 2 on the expansion board #2 or automatically if the outside ambient temperature is grater than
35°C and disabled when it falls below 34°C) is managed. It allows the compressor to run at its full
speed of 90Hz if the maximum available capacity is reached. When the overboost is disabled the
