2. IC2401 (MEGATEXT).
The original IC2401 is RH-IX1673BMZZ (SDA5273-2). It has been temporally used the alternative RH-IX1709BMZZ
(SDA5275-3). Please Note that the most important change is that when the alternative one is used, it must be added
IC2402. See Fig. 15, in order to know how both ICs are implemented.
