| 13 | |||
| 14 | 20 | Alessio Valeri | There are 2 HBS interfaces available. One is used with the communication with the master controller ( Indoor display ) and the other one is used for the communication between outdoor/indoor unit (in my case they are both outdoor) and remote control with the auxilliary Hi-mit II remote controller (HCCS-H64H2C1M). Both can be found at CNx of PCB1 and they are routed differently between the monoblock/split units. |
