Control management 5 Inverter controller GMC controller 30AWH012_ 30AWH015_ 30AWH004_ 30AWH006_ 30AWH008_ Wired remote (RC1) Code: 33AW-RC1_ Wired remote (CS1) Code: 33AW-CS1_ 55 SM_30AW.
5 Control management 5.1 Introduction USER INTERFACES GMC CONTROL INVERTER CONTROLLER Users can select the desired operating NPEF UISPVHI EJòFSFOU SFNPUF DPOUSPMMFST Control is based on the GMC platform developed by Carrier. For the 30AWH AquaSnap PLUS inverter chiller / heat pump a new GMC board has been developed as well as new algorithms have been implemented. The GMC control elaborates the request from the user interface and translates it into a message for the chiller unit control.
Control management 5 When power supply is reset When a unit is powered up, depending on its Auto Start configuration, it will start up with its last operating parameters, or OFF Mode. The EEPROM is available for saving the operating environment of the control in the event of a power-reset condition. If not configured for auto start, at the power up the system will remain in OFF Mode. All the NUI codes will be restored on a power up condition.
Control management 5 Operating mode selection The operating mode is selected based on the command chosen by the remote control. Cooling Mode Depending by the system configuration and when the operating mode is cool, the system could operate as follows: With Comfort NUI (CS1). With SUI (RC1) / Dry inputs. The WSP (Water Set Point) will be defined as follow: - Fixed WSP: as per the appropriate variable value (Standard and Eco) - Climatic Curve depending by OAT (see the controls manuals and the paragraph 7.
Control management 5 Dehumidifier activation (X and H terminal block pins 11 – N) External dehumidifier source is based on NUI Relative Humidity value, (For this feature is necessary install 33AW-CS1 interface). Two codes shall be accesses through NUI: Code 108: It is for defining availability of external dehumidifier. 1 = Alarm or Defrost 2 = External Dehumidifier activation Code 107: - It is Relative Humidity Limit value to activate the heat source.
Control management 5 High Temperature Protection When the water starts to get to hot, this is a sign that the pressure in the system is increasing. Certain actions are taken to decrease the pressure. Tw: Max(Actual Water Temperature Entering, Actual Water Temperature Exiting) Tr: Actual Refrigerant Temperature Fr(n): real frequency from the chiller unit Fhmin: minimum compressor speed allowed in heating Tw Compressor OFF 62 °C M 61 °C L 60 °C N While in Zone N or L the frequency can’t increase.
5 Control management Unit Status and Defrost output or Tair Setpoint status Based on the NUI code 147 set-up, the Output J7 Pin 2 (N-5 on the terminal block) could play for one of these Functions: - ALARM: The intent of this output is to point out the alarm condition. This signal could be used by an external control to verify if the Unit is able to operate with the requested function.
Control management 5 Backup External Heat Source functionality (X and H terminal block pins 5 – N) This functionality is valid when user mode is HEATING MODE. Between pins 5 and N of terminal strip (see paragraph 4.1) an output is available (1 ph ~ 230V, 2A max) to activate a backup external heat source (such as Electric Heater or Boiler). This functions is activates using the NUI.
5 Control management System Diagnostics The control contains diagnostic tests to verify the integrity of the system. The On Board LED is located on the circuit board. It is used to display normal operation status and diagnostic fault code information. The control board status LED will flash at a rate of one (1) second ON and one (1) second OFF while the control is operating normally. When in a diagnostic fault code, it will blink out the fault code. Once a failure occurs, the system is considered failed.
Control management 5 Discharge temperature release control 1) This function controls the compressor frequency, when the discharge temperature has increased due to max load condition or during PMV control. It subdivides the frequency control up to a unit of 0.6 Hz to stabilize the cycle. 2) When the discharge temperature is detected in an abnormal stop zone, the unit stops the compressor and restarts it after 2 minutes, 30 seconds (time guard).

Control management 5 2) Heating fan control 004-006 sizes The blowing air volume at the outdoor unit side is controlled as follow: 1. When strong wind blows at outdoor side, the operation of heat pump continues with the fan motor stopped. 2. Whether the fan is locked or not detected, and the operation of heat pump stops and an alarm is displayed if the fan is locked. 3.

Maintenance 8 8.1 Refrigerant charge check IMPORTANT: All maintenance operations must be performed by qualified personnel. This check becomes necessary after any refrigerant leak or after replacement of the compressor. The best method to correctly charge refrigerant is to completely empty the refrigerant circuit using refrigerant recovery equipment. Then charge the exact quantity of refrigerant according to the data shown on the unit nameplate. R-410A systems must be charged with liquid refrigerant.
