Set the "MODE" to 1 or 2 if an outdoor Sensor is not used (1 = parallel piping, 2 = primary/secondary piping)
Caution:
“Factory” position on dip switch has to be returned to “installer” position to prevent unauthorized changes to factory settings.
*Local design input may vary from the example shown. Be sure to use design inputs for your geographical location.
EXAMPLE SETTINGS MAY VARY ACCORDING TO ACTUAL DESIGN REQUIREMENTS.
