The pressure switch module, compatible with the FRZ and FRZB Series, plays a crucial role in system functionality. However, it’s important to note that this module cannot be used with the FRZ Series FRZ3_ or RZ3_ models. By understanding this limitation, you can ensure compatibility and avoid installation issues
