Control board UTA FM792 2 resistors 230/1/50 – code: TA2055B – Climma

UTA FM792 Climma control board (TA2055B) for units with 2 resistors

The UTA FM792 control board 2 resistors 230/1/50 (code TA2055B) Climma is a electronic control board intended for Air Handling Units (AHU) of the FM792 series configured with two electric resistors and power supply 230 V single-phase – 50 Hz. This is the control unit that coordinates the management logic of the unit, receiving signals from the sensors and commanding the main components based on the system settings.

In spare parts context, the TA2055B is used as original spare part to restore the correct operation of the UTA in case of anomaly or failure of the existing board, maintaining the control architecture provided by the manufacturer.

Main features and details

Inside a UTA with electric heating, the control board plays a central role: it manages operation requests and coordinates the activation of components, with particular attention to the management of heating stages and associated protections.

Functions managed by the board

• UTA FM792 control: management of the operational logic of the air handling unit.
• Management of two electric resistors: command for activating the resistors based on signals and system settings.
• Signal acquisition: reading signals from temperature probes and safety devices.
• Component control: management of the fan and other unit elements provided by the configuration.
• Functionality restoration: replacement of the electronic board in case of failure to restore the AHU to operational conditions.

Product identification

• Spare part code: TA2055B
• Application: Climma AHU FM792 with 2 resistors
• Unit power supply: 230/1/50 (230 V single-phase – 50 Hz)

Typical applications

The TA2055B board is suitable for maintenance and repair interventions on Climma FM792 AHU where the electric heating management is done through two resistors. Specifically, it is used when it is necessary to restore the correct management of:

• ventilation and unit controls;
• activation logic of the electric resistors;
• reading of probes and management of safety consents;
• overall operation of the AHU based on system settings.

In the context of technical plant engineering (including onboard system maintenance), replacing the control board is a typical operation when malfunctions related to the management electronics are detected, provided that diagnosis is performed on the unit and associated wiring.

Advantages for maintenance and spare parts

Using a spare part identified by the correct code allows for orderly intervention on the machine, maintaining the configuration intended for the FM792 AHU with two resistors.

• Targeted spare part: TA2055B code dedicated to the specified configuration.
• Integrated management: centralizes commands and acquisitions (probes and safety devices) necessary for the operation of the AHU.
• Support for operational continuity: replacement of the board in case of failure to restore the unit to service.
• System consistency: maintains the control setting provided for 230/1/50 units with two resistors.

Usage and important notes

The control board is an electronic component intended for installation in AHU: the intervention requires technical skills and a proper system check. For a correct replacement, it is good practice to:

• verify that the unit is actually a Climma FM792 AHU format 2 resistors;
• check the correspondence of the code TA2055B with the replacement to be installed;
• ensure that the unit's power supply is 230 V single-phase – 50 Hz as indicated;
• perform a diagnosis on probes, safety devices, and wiring to exclude causes external to the board failure.
