Level H3: <value> Virtual water level in cm from the top of the tank. Turning on make-up valve for water
filling and turning off the dry run protection from idle. See Buffer tank picture in chapter 3.16.2. for better
understanding.
Level H4: <value> Virtual water level in cm from the top of the tank. Turning on the dry run protection and
blocking the filtration pump. See Buffer tank picture in chapter 3.16.2. for better understanding.
Time H1: <adjustable from 0 to 10 Hours in 30min. steps.> Default is 3 hours. Indicates after how much time
the forced pumping will be turned off when the upper Level H1 is active. Despite a full tank, after this time
the forced pumping will be disabled. This is important for outdoor pools where rain can cause too much
water in the pool.
Time H1 and H2: <value> value in hours. Indicates after how much time the forced pumping will be turned
off when the top level H1 is already inactive but level H2 is still active.
Recomm. value H1-H4: Displays recommended values for each of the security levels based on dimensions
of the buffer tank.
H1-H4: displays actual active measured water level in the buffer tank.
After performing setup or any changes to this section, click „SAVE SETTINGS” to save configuration to
