High Suction Pressure

Hva betyr HISUC ?

The suction pressure has risen above the level set in Q5-12 for longer than the time set in Q5-13. This fault is effective only when Q5-14 (High Suction Pressure Behavior Select) is set to 2 (fault).

• System suction pressure is too high, exceeding the Q5-12 threshold for the Q5-13 duration.
