Loading…Secondary circuit board
A secondary PCB for an ALPS EXCLUSIVE Urban V2 heat pump supports specific electronic functions within the control system. Depending on the version, this PCB may be used for current detection, power monitoring, signal processing or support of other electronic components.
When replacing a secondary PCB, always check the original PCB type, article number, connector layout, supply voltage, function within the system and compatibility with the relevant Urban V2 model. This helps prevent faults, incorrect readings and communication issues after installation.
Choosing a secondary PCB
A secondary PCB for an ALPS EXCLUSIVE Urban V2 heat pump is selected based on its electronic function within the system. This type of PCB may be used for current detection, power monitoring, signal processing or additional support of the main controller.
During replacement, the PCB must match the original component exactly. Pay attention to article number, PCB code, connector layout, electrical connection, measuring function and compatibility with the relevant Urban V2 model.
Important when selecting secondary PCBs
- Always check the original article number and PCB code.
- Pay attention to the function of the PCB, such as current detection or power monitoring.
- Carefully compare connectors, plug connections and cable positions.
- Check whether the PCB is suitable for the relevant Urban V2 model.
- In case of faults, also check power supply, wiring, sensors, main PCB and communication.
- Have diagnostics, installation and function testing carried out by an installer or service technician.
Technical function inside the heat pump
The secondary PCB works together with the main controller of the heat pump. While the main PCB often provides central control, a secondary PCB supports specific measurement, detection or signal functions required for safe and stable operation.
A defective secondary PCB can cause fault messages, abnormal readings, power-related faults, communication issues or incorrect control of connected components. Targeted diagnostics help prevent unnecessary replacement of other parts.
Frequently asked questions
What is a secondary PCB used for?
A secondary PCB supports specific electronic functions inside the heat pump, such as current detection, power monitoring, signal processing or communication with other components.
Is a secondary PCB the same as a main PCB?
No, a main PCB usually handles central control. A secondary PCB supports additional functions and often works together with the main PCB and other electronic components.
Does every secondary PCB fit every Urban V2 heat pump?
No, the PCB must match the correct model, article number, connector layout, technical function and heat pump version. Always check the original component before ordering.
When does a secondary PCB need to be replaced?
Replacement may be required in case of proven electronic defects, damaged connections, incorrect readings, communication problems or recurring faults after complete diagnostics.
Should other components also be checked?
Yes, also check power supply, wiring, plugs, main PCB, sensors and connected components. A fault message may originate outside the secondary PCB itself.
