- EXTERNAL RELAY: Ex_Relay 1, Ex_Relay 2
- INTELLICHLOR: All Models (IC20, IC40, IC60)
Flow (Rate) 2/2:
- INTERNAL PUMP (MTR_R/MTR_L): FLOW: 65 GPD (gallons per day)
- EXTERNAL RELAY 1 or 2: RATE: xxx GPD (gallons per day). Note: Set

Controller alarm output information:
- External alarm output: Ex_Relay1 or Ex_Relay2.
For an external alarm indicator, an unused relay may be selected to turn
on when the red Alarm LED on the front panel is turned on.
The alarm relay must be chosen carefully. If Ex_Relay1 or Ex_Relay2 is
used for a doser, it must not be used for an alarm output. Upon exiting the
Hardware menu, the program will check to be sure the same relay is not
used more than once. If a relay is assigned to more than one function, an
error message will be displayed.
