  5) TRIAC TC OUTPUT In certain models, the device has a high voltage Triac output which is typically used for piloting the fans/continuous compressors. The output can be configured for proportional operation (constant speed variation) or as ON/OFF; If configured as a proportional output, the phase parameters and the pulse length of the Triac must be properly configured for better adaptation to the load characteristics.

• Page 31: Compressor Control

  COMPRESSOR CONTROL The device can be configured to manage an inverter compressor or one or more homogenous digital compressors (max. 4) by setting parameter CP22: Parameter Description Notes 0=inverter compressor. Number of compressor steps CP22 ≠0=CP22 represents the number of digital per circuit compressors.

• Page 32: Inverter Compressor Control

  One or more digital inputs can be configured as compressor block inputs:  Digital inputs DI1…DI7. Analogue inputs AI3 …AI4 if configured as digital inputs.  It is also possible to configure a relay as compressor INVERTER enabling output. Inverter compressor control The operating mode depends on parameter ST02.

The above drawing represents only the nominal case in which the cut-off hysteresis is enabled at the minimum. Parameters CP08 (enable minimum cut-off) and CP09 (enable saturation cut-off) activate or deactivate the cut-off function.

• Page 34: Digital Compressor Control

  Digital compressor control The regulator calculates the number of refrigeration resources required by the system through a policy of assigning resources selectable with parameter CP10 (Activation policy). Activating or deactivating power steps must respect the activation and release times for resources CP15 and CP16 which are loaded on activation/release.

The operation depends on the parameter ST02: Cooling mode if St02=1 and Heating mode if St02=0. The main function of the regulator consists in activating/deactivating a number of resources (discrete power steps) linked to the time in which the intake probe takes on values outside of the symmetric proportional band in…

• Page 36: Compressor Timing

  No variation in power is required within the PROPORTIONAL BAND. Hysteresis is not included in this algorithm. All interstep times are resynchronised upon the activation/deactivation of a new compressor combination. In the case of an regulation probe error, the number of active steps is calculated as a percentage set for the CP21 parameter of the total number of steps.

• Page 37: Power Stages

  The activation and deactivation of power steps for digital compressors must respect the activation and release times for resources (parameters CP15 and CP16). Power stages For a segmented compressor in which the number of steps corresponds to the number of segments plus one, the segmentation actuation mode depends on parameter CP11.

• Page 38
  Parameter Description M./U. Notes CP10 Activation Policy Num 0= fixed sequence 1= balancing 2= saturation The selection policies are based mainly on the hours of operation of the compressors. They come into play when the regulator requests the activation/deactivation of a step. This request is then distributed to the most suitable compressor according to the compressor selection policy selected using CP10.

  By setting parameter Fn25=-1 it is also possible to define that the fan is absent (no condensation) and the relative regulator will not be actuated. If a probe is configured as a temperature probe or outlet pressure probe, the condensation regulation is proportional or Neutral Zone (NZ). In the case of pressure regulation, the AI4 probe must be used (low resolution probe).

• Page 41
  • 0 = the regulator immediately sets the output proportional to the speed specified by parameter Fn23 and maintains this speed for the time specified by parameter Fn13. • 1 = the regulator actuates the proportional output according to a ramp that allows the speed specified by parameter Fn23 to be reached in the time specified by parameter Fn13.
• Page 42
  Parameters Fn08 (enable minimum cut-off) and Fn09 (enable saturation cut-off) activate or deactivate the cut-off function. Note that if the minimum cut-off is disabled, the speed of the fan goes from 0 to the minimum speed when the regulation probe reaches the set point from “below”. If the regulation probe reaches the setpoint from “above”, the speed will go from minimum speed to 0.

Inverter preventilation (cold mode only) If parameter Fn10=1 (if the compressor is OFF, the fan is OFF) and Fn15<>0, the preventilation is also active.

• Page 44: Digital Fan Control

  DIGITAL FAN CONTROL Pick-up On each activation request by the regulator, all of the exchanger fans are activated simultaneously for a time equal to the value set using parameter Fn13 (pick-up time). After this time has elapsed, the fans will be piloted at the speed set by the regulator. If, during the pick-up time, the regulator wants to turn the ventilation off, the fans will be switched off.

• Page 45
  If Fn10=0 then the condensation control is independent of the compressor, if, however, Fn10=1 then the fan is off when all of the compressors available are off. The cut-off at minimum is bypassed for the time set at parameter Fn14 after the compressor is activated. If the regulator requests the switching off of the fans during this time, the fans will be piloted at the minimum speed (1 step).
• Page 46
  During the ON phase, the number of fans that are switched on in comparison to the number of those present is a function of the value set for parameter Fn24. If a condensation probe has been allocated, the fan control will be in steps with a neutral zone in function of the value of the condensation probe and the set times.

  Digital fans rotation In the case of step fans, rotation of the fans can be controlled during activation and release by means of parameter Fn11. If Fn11=0 (fixed sequence), the activation sequence is fan 1, fan 2, ..fan n; The sequence is inverted during deactivation, e.g.

  Fans thermal switch The intervention of the digital fan thermal protection is blocked for the correctly used fan. If another fan is available it will be selected depending on the policy (Fn11) and immediately activated. The contemporaneous intervention of the thermal protections of all of the digital fans causes an alarm which blocks the machine.

• Page 50: Recording Operating Hours

  Recording operating hours The device records the operating hours of the compressors and fans; This data is visible in the Hr folder and is called CP0n (nth compressor hours), Fn0n (nth fan hours). For values lower than 9999 the entire value is displayed, for higher values the hours/100 are displayed and the decimal point is activated.

• Page 51: Alarms

  ALARMS The alarms can be one of 3 types: Automatic reset alarm: alarm active if the cause of the alarm is present, otherwise not. Manual reset alarm: alarm active if the cause of the alarm is present, if the cause of the alarm has ceased the alarm can only be reset manually (by simultaneously pressing the UP and DOWN keys).
