TBD: Proportional Band
The proportional band is set as an offset of above the set TDS target
value, within the proportional band, the PID control will make corrections
during the blowdown time to maintain the TDS target value. If using a
solenoid valve or servomotor (2-state) TDS control, then the P element
will determine how long the valve is fully open for before it goes to fully
closed, during the blowdown time. If using servomotor continuous TDS
control, then the P element will determine what angle the valve is opened
to during the blowdown time. If the measured is above this proportional
band, then the solenoid valve or top blowdown servomotor will remain fully
open.

TBD: Integral Time
For a slower response, increase the integral time. For a quicker response
with fast changing TDS values, decrease the integral time.

TBD: Derivative Time
For water level with a quickly changing TDS value in the water, a
derivative time can be added to prevent overshoot.

TBD: Servo Open Angle
The TDS servomotor closed position is set by zeroing the potentiometer in
commissioning mode. As
default the servomotor is set as fully open,
however this setting can be decreased to shorten the operational
movement range of the servomotor.
