As the PID feedback value below P7.16 set detection threshold, the accumulated delay time
P7.18 seconds later, it is judged to feedback disconnected. The action will be defined by the
parameter P7.17 selection after feedback offline.

P7.19 Wake up pressure level. Range
：
0.001~P7.20 0.001
This parameter defines the system from a hibernation state to enter the working state of the
pressure limit.
As the pipeline pressure is smaller than the set value, illustrate the tap water pressure to
reduce or increase in the water content, frequency conversion water supply system
automatically from the dormant state to state.
P7.20 Hibernation pressure level Range
：
P7.19~P7.27 1.000
This parameter defines the system enters a hibernation state stress limit value.
As the pipeline pressure is greater than the set value, and the frequency of water supply
systems have been adjusted to the hibernation frequency operation, descriptions of actual
water decrease sharply or tap water pressure increases, the frequency of water supply
system to automatically enter a state of dormancy, stop wait wake.
As the water supply system to reach the awake and hibernation condition, enter the
awakening and hibernation latency by the parameter P7.21 and P7.23 to determine.
