One of the new features of the H100+ is its sleep monitoring function.  With the H100+ frequency monitoring for the Sleep Activate level start only when the output frequency is greater than the Sleep Activate level. Without having to separately set a sleep level and activate level the unit is automatically set on its minimum frequency.

When Sleep Off mode is activated will be turned off after entering Sleep mode during PID operation. With this status, wake-up is not operated at the wake-up level but only by pushing the Auto key.  This function can be used when Wake-Up is not to be operated based on the pressure feedback. This makes it ideal for some submersible pumps.
