11.7 Water Hardness Monitoring
Feed Water Hardness can be continually monitored using Water Hardness Monitoring feature, to enable this
feature, Expansion Option 40 must be set to 4 – Water Hardness Monitoring. When this option is selected,
the TDS probe will continually measure the feedwater hardness and will output live readings on the home
MM screen.
The use of a TDS probe is required with a TDS probe pot, this is mounted directly into the feedwater flow to
allow the TDS probe to measure the hardness level in the feed water.
To enter the Water Hardness information screen, press on the TDS probe on the home MM
screen, this displays information about the current water hardness reading as well as a graph which records
the water hardness history for the past 24 hours.
A water hardness warning level can be set in Expansion Option 46 so that an MM alarm will be triggered if
this threshold is reached. An alarm level can also be set in Expansion Option 56, this information will also be
displayed in the water hardness screen.
