2. Set Points
The same basic format is used for defining each available analog probe input's control
parameters. Boiler conductivity systems will also have an additional menu step for
programming the sampling method desired from continuous, timed or sample and hold.

3. Calibration
Calibration is for adjusting the unit's displayed value of a probes reading to match your tester or known
solution.

SET POINTS – For setting the relay set points
for the available analog probe readings such
as conductivity, pH, ORP or temperature.
If there is more than one System present you
first select which system's values are to be
adjusted.
SET POINT – What reading turns the relay on
DIFFERENTIAL –Amount reading changes by
before the relay is turned off
HIGH ALARM – What reading generates a High
alarm notification.
LOW ALARM – What reading generates a Low
alarm notification.
LIMIT TIMER- What amount of continuous
bleeding will generate a time alarm notice.
CALIBRATION – For adjusting the actual
reading values of the available analog probe
inputs, such as conductivity, pH, ORP or
temperature.
CALIBRATE – With a clean probe on-line
seeing the system's water enter the known
(tested from a calibrated hand held tester) value.
RESET ZERO – With the probe out of solution
and dry enter a new zero point.
Note: Probe must be dry!
