6.4 Circuit Board Jumpers (All Export 50 Hz 1-Pump Models)
These circuit boards can be configured for 20A or 30A logic. Each mode affects overall energy consumption
and heater performance.
Pins 1-2:
Jumper ON
Enables 20A logic; forces heater off when jets pump 1 is running in high speed
Pins 1-2:
Jumper OFF Enables 30A logic; allows heater to operate when jets pump 1 is running in high
speed
Pins 3-4:
Jumper ON
Enables 2 Pump Operation (2-pump models only)
Pins 3-4:
Jumper OFF Enables 1 Pump Operation
Pins 5-6:
Jumper ON
Not Used
Pins 5-6:
Jumper OFF Not Used
Pins 7-8:
Jumper ON
Enables Celsius (°C) temperature display
Pins 7-8:
Jumper OFF Enables Fahrenheit (°F) temperature display
6.5 Circuit Board Jumpers (All Export 50 Hz 2-Pump Models)
These circuit boards can be configured for 20A, 30A or 40A logic modes. Each mode affects overall energy
consumption and heater performance.
Pins 1-2:
Jumper ON
Enables 20A logic; forces heater off when either jets pump is on high speed (Pump
2 only runs in high speed)
Pins 1-2:
Jumper OFF Enables 30A logic; allows heater to operate with one jets pump running in high
speed
Pins 3-4:
Jumper ON
Enables 2 Pump Operation
Pins 3-4:
Jumper OFF Enables 1 Pump Operation
Pins 5-6:
Jumper ON
40A logic (Remove JP1 1-2 Jumper); allow heater to operate with both jets pumps
running in high speed
Pins 5-6:
Jumper OFF Leave off for 20A or 30A logic setting
Pins 7-8:
Jumper ON
Enables Celsius (°C) temperature display
Pins 7-8:
Jumper OFF Enables Fahrenheit (°F) temperature display
