17.1 MAXIMUM TIME OF NEUTRAL ZONE STAY WITHOUT INSERTION OF
RESOURCES WITH AT LEAS ONE RESOURCE INSERTED
Par. CO50
With at least one compressor on, when the functioning is into the neutral zone, is calculated the time set by the par. CO50 after which is
forced a compressor or partialization step insertion.
The resolution is fixed on dozen minuts if the parameter value is 0 the function is deactivated.
17.2 MAXIMUM TIME OF NEUTRAL ZONE STAY WITHOUT THE RESOURCES
ROTATION
Par. CO51
When the functioning return into the neutral zone, is calculated the time set by the par.CO51 after which the busy compressor is turned
off and depending on the rotation, another compressor insertion is forced.
The resolution is fixed on hours if the parameter is 0 the function is deactivated.
17.3 THERMOREGULATION OF THE COMPRESSOR INVERTER CONTROLLED
MANAGEMENT OF COMPRESSORS INVERTER CONTROLLED
The signal 0÷10V is given by one of 4 configurable ouputs of the instrument; it’s possible to have up to 2 steps per circuit, 1 modulating
comp. and 1 ON/OFF compressor.
Regulation:
• when the compressor is activated the capacity percentage is forced at the maximum speed (CO55 parameter); after this:
• if the parameter CO56=0 the capacity percentage is forced at maximum speed for CO54 seconds; when CO54 time is
elapsed the controller modifies the capacity percentage following thermoregulation requests
• if the parameter CO56≠0 the capacity percentage is increased of 1% every CO56 seconds. When the capacity
percentage reach 100%, the controller modifies the capacity percentage following thermoregulation requests
• when the compressor is working, the capacity percentage is increased/decreased of 1% every CO65 seconds
• when the compressor is working, if the capacity percentage is lower than CO57 value for CO58 minuts, the compressor is
forced to work at 100% for CO59 seconds
• if the unit manages two compressor inverter controlled, when one compressor is working continuosly for CO60 hours, it is
forced OFF and the other compressor is switched on
UNIT IN CHILLER
Compressor activation:
when the compressor is activated the capacity percentage is forced at the value configured in CO55 parameter for CO54 seconds.
When is requested the activation of the second compressor:
