When setting a holiday the Heatmiser sometimes gives a status like this:
```
94 51 00 00 00 48 00 48 00 00 0d 02 00 02 01 00 00 00 00 00 00 00 14 00 11 12 1c 00 01 01 00 00 0c 02 16 0f 23 00 00 00 ff ff ff ff e2 00 00 00 00 00 16 03 0f 23 0c 06 00 16 08 1e 12 10 1e 17 17 00 12 08 00 17 17 00 12 18 00 10 18 00 10 da cb
```
The year and month bytes (bytes 48 & 49) come out as zeros, which isn't valid.
