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:

3HVAC OutputRJ45-2

The CAT-5 is hooked to the screw terminals as follows:
