Spare part features and details

Product identification

• Brand / manufacturer: Frigomar
• Description: Main MCU Control Board
• Type: main electronic board (Main MCU control module) for Frigomar chillers
• Product code: ECPCBCOM005

Component function (Main MCU)

The Main MCU constitutes the main control unit of the chiller. Functionally, this module is responsible for managing the electronic functions of the system, including:

• control of the chiller's operating logic;
• management of signals from sensors;
• coordination of compressor operation BLDC Inverter;
• management of protections and alarms;
• communication with the display and other electronic modules of the unit.

Frigomar documentation identifies the Main MCU as the main control module installed in units of the CU series.

Applications and compatibility

Compatible Frigomar chillers (verified)

The replacement ECPCBCOM005 is intended for the following Frigomar chillers:

• CU50VFD
• CU50VFDT
• CU70VFD
• CU70VFDT
• 609
• 610

Usage context

The component is used as original spare part for Frigomar chillers series CU50 and CU70, including models 609 and 610. It is a central element of the control electronics and, consequently, the correct identification of the model is essential to avoid incompatibilities.

Advantages for maintenance and spare parts

In a centralized air conditioning system, the main board is a critical node for managing functions and internal communications. Choosing a replacement identified by Frigomar code allows for orderly maintenance operations, maintaining consistency with the configuration provided by the manufacturer.

• Specific replacement for CU series: suitable for the units listed in compatibility.
• Centralized management: the Main MCU coordinates the unit's logic, signals, and interfaces.
• Support for protection functions: involved in managing system protections and alarms.
• More straightforward maintenance approach: targeted replacement of the main module in case of electronic failure.

Usage and operational notes

Checks before purchase

Before proceeding with the order, it is recommended to verify:

• the spare part code reported on the installed board (ECPCBCOM005);
• the chiller model (for example CU50VFD, CU70VFD, 609, 610);
• any correspondence with the unit's technical documentation.

Installation

The Main MCU is an electronic control component: installation and diagnosis are typically tasks to be performed by technical personnel. In case of doubts about compatibility or replacement identification, it is preferable to compare code and model before replacement.
