and runs at variable speed.
3 Flashes Off Heat Pump Mode
– Heat Pump Heating. Compressor, fan and circulator on – circulator at full speed.

Notes
1. All faults will trigger Element Heating, except Fault 9 (9 red flashes).
2. Fault 9 will not disable all heating unless it has occurred 3 consecutive times. On the first and second consecutive occurrences of Fault 9, the heat pump will return to System Check.
3. To reset Fault 9 or cancel the start delay, press and hold the reset button until both LEDs come on.
4. The refrigerant high pressure switch is manual reset and may also need to be reset following the occurrence of Fault 9.
