PC04 = Compressor minimum ON time. Once it has been activated, a compressor must remain ON
for this time interval, before it can be switched OFF again.
PC05 = Compressor minimum OFF time. This is the minimum time interval that must elapse from
the last switching-OFF, before the compressor can be switched back ON again.
PC06 = Minimum time between switchings-ON of the same compressor. It determines the minimum
time which must elapse between two switchings-ON of the same compressor.
PC07 = Minimum time between switchings-ON of different compressors. It determines the
minimum time which must elapse between the switching-ON of a compressor and that of the next
one.
PC08 = Minimum time between switchings-OFF of different compressors. It determines the
minimum time which must elapse between the switching-OFF of a compressor and that of the next
one.
PC09 = Maximum number of compressor start-ups within one hour. This determines the maximum
number of switchings-ON within the time span of one hour: should this limit be reached, the
regulator will wait until conditions are present, before switching that compressor ON again.
Neutral-zone timings
These parameters are used to time the request for switching ON/OFF the various compressors.
PC17 = Extra time for ON/OFF switching request
6.6.6 Thermal protection inputs
The program provides for the management of a compressor thermal safety switch input for each
compressor. For this input, it is possible to set, via parameters, the type of reset (manual or
automatic), as well as the triggering delay.
In order to enable the alarms connected with these thermal protections, in addition to setting the
aforementioned parameters, it is also necessary to set, in the CoSt->HArd menu, the position in
which the digital inputs pertaining to these alarms are to be connected. If no alarm is to be set, it is
sufficient to set the above parameter to 0.
