  REGULATORS 16.1 DIGITAL COMPRESSOR REGULATION Set par. oA1 and oA3 as below indicated to manage Digital (Scroll or Stream D4D) compressors: oA1=dGt or d4d oA3=dGt or d4d The cooling demand acts on the Digital compressor that, unless of alarms, delays or par. FrC=n, is the first to be activated and the last to be deactivated.

• Page 28: Capacity Decrement And Regulation Stop

  NOTE: If the pressure exceeds the [SET+0.5*HY1] value and the Digital compressor is not available (due to the timer delay 2on, 2oF or because of digital input alarm lockout), another compressor will be started (if available). 16.1.2 Capacity decrement and regulation stop When the pressure goes below the value [SET-0.5*HY1] the Digital compressor will be controlled in PWM modulation, at the minimum allowable capacity, for the time toF.

  It is possible to drive inverter with control signal of frequency or voltage (0-10 V DC) type. NOTE: the analog output is not configurable. It may be frequency or voltage type depending on the hardware. 16.2.1 How regulation works The regulation starts when the value of the pressure/temperature of the suction line increases and reaches the St1 value.

  17.3 “BUMP” FUNCTION This feature is available only using ON-OFF compressors and if par. bMp=Y. When regulation starts, the compressor will be activated and deactivated for a nub number of cycles and with a duration respectively set in par. bon and boF. During the «BUMP» phase pressure/temperature alarms are ignored.

• Page 35: Reading Filter

  17.6 READING FILTER It is possible to activate a reading filter which acts on the analogue input values (eg. Pressure/temperature values coming from probes). Following the involved parameters: FiC=mEd, the used value for regulation is the average value calculated on the interval of time tdG FiC=1…100, the used value for regulation is the one calculated by an exponentially weighted moving average filter with coefficients FiC/100.
