Hatty
Hatty uses a Hobby-Boards temperature sensor board wired in a unique manner. The system cable comes into the screw terminal strip, DQ and Gnd. The Cat-5 cable Blue goes to DQ and Blue-White to Gnd.
The two RJ45's on board are used to connect two temperature sensors. In addition, there is a temperature sensor mounted on the board. This board thus accommodates three temperature sensors.
The sensors are defined in the following table:
Sensor | Location | Port |
1 | Ambient | Onboard |
2 | HVAC Input | RJ45-1 |
3 | HVAC Output | RJ45-2 |
The CAT-5 is hooked to the screw terminals as follows:
Color | Signal |
Blue | Data (DQ) |
Blue-White | Gnd |
