A. The Display control changes the contrast on
the LCD display. You will probably never touch
it unless the temperature around the unit is
unusually high or low. If there is no information
on the display, someone probably fiddled with the
control. Bring it full counterclockwise and then
back off until you have the desired contrast.
B. The Solenoid output provides 12 volts DC for
the pump's integral solenoid. You must use the
correct pump solenoid for the pump to operate
properly.
C. The Switch terminal connects the control
switches to the system. You can remotely Run,
Pause and Stop the system by connecting
remote momentary dry contacts to the propriate
terminals.
D. The 110 VAC (also available in a 220 volt version)
input is the only way to power the unit. Make
sure the connections are neat and that for safety
reasons no conductor is exposed. This is the only
location on the circuit board where more than 12
volts is present.
