7. Feed Water Hardness (Display Code H)
Press the Extra Cycle button. Use this display to set the feed water hardness. Enter
the feed water hardness in grains per unit volume for softener systems, or 1 for filter
systems. This option setting is identified by "H" in the upper left hand corner of the
screen. The feed water hardness parameter is only available if the control type has
been set to one of the metered options. Use the Up and Down buttons to adjust the
value as needed.
Range: 1 - 100 Hardness
NOTE: The hardness level should be set 5 GPG above the actual water feed
hardness. The hardness level from the original feed water test will either be ex-
pressed in GPG (grains per gallon) or ppm / mg/L (parts per million / milligrams
per liter). If the reading is in ppm / mg/L, then divide that value by 17.1 to get
GPG. This system only allows hardness inputs in GPG.
8. Reserve Selection (Display Code RS)
Press the Extra Cycle button. Use this display to set the Reserve Selection. Use
this display to select the type of reserve to be used in your system. This setting is
identified by "RS" in the upper left hand corner of the screen. The reserve selection

options. There are two possible settings:
