Notes:
1. When the TEST jumper is removed, the green status LED will be off.
2. The source heat exchanger freeze/water ow fault sensor is located between the TXV and source heat exchanger.
3. The load heat exchanger freeze sensor is located between the TXV and the load heat exchanger.
4. Only package and Water-to-Water models have this feature.
5. This fault indicates a bad sensor - open, shorted, disconnected, or invalid value.
6. Check for T1 & T4 being swapped (only shown in TEST mode).
7. Hot Gas Line temperature is too high (>220F).
8. Units without HWG do not use sensors T2 and T3. The control will disable faults 15 and 16.
