6.0 Understanding Circuit Board Pin Assignments
6.1 Circuit Board Jumpers (All North American 60Hz 2-Pump Models)
All North American 2-pump circuit boards can be congured for either 40, 50A, or 60A operation.
Refer to jumper pin table and circuit board diagram below for specic system details (factory jumper
settings shown):
Circuit Board #6600-293; Micro Chip 3.82+ (started started July 15, 2014)
Pins 1-2: Jumper ON Enables 40A logic; heater will not operate while any
pump is running.
Pins 1-2: Jumper OFF Enables 50A logic; heater will operate while one pump
are running. This is the factory default.
Pins 3-4: Jumper ON Enables 2 Pump Operation
Pins 3-4: Jumper OFF Not Used. (Enables 1 Pumps Operation)
Pins 5-6: Jumper ON Enables 60A logic; (Remove JP1 1-2 Jumper). Allows
the heater to operate when both pumps are on running.
Pins 5-6: Jumper OFF Leave off for 40A or 50A Logic
Pins 7-8: Jumper ON Enables Celsius (°C) temperature display
Pins 7-8: Jumper OFF Enables Fahrenheit (°F) temperature display
6.2 Circuit Board Jumpers (All Export 50 Hz 2-Pump Models)
These circuit boards can be congured for 20A, 30A or 40A logic modes. Each mode affects overall
energy consumption and heater performance.
Pins 1-2: Jumper ON Enables 20A logic; heater will not operate while any jets pump is running.
This is the factory default.
Pins 1-2: Jumper OFF Enables 30A logic; heater will operate with one jets pump running.
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
6.3 Circuit Board Jumpers (All North American 60 Hz 1-Pump Models)
All North American 1-pump circuit boards can be congured for either 120V/15A or 240V at 30A or
40A operation. Refer to jumper pin table and circuit board diagrams below for specic system details
(factory jumper settings shown):
Circuit Board #6600-295; Micro Chip 3.82+ (started July 15th 2014)
Pins 1-2: Jumper ON Enables 15A logic; forces heater off when pump is on
high speed (3-wire 120 VAC operation only). This is
the factory default.
Pins 1-2: Jumper ON Enables 30A logic; forces heater off when pump is on
high speed (4-wire 120/240 VAC operation only)
Pins 1-2: Jumper OFF Enables 40A logic; allows the heater to operate when
pump is on high speed (4-wire 120/240 VAC opera-
tion only)
Pins 3-4: Jumper ON Not Used
Pins 3-4: Jumper OFF Enables 1 Pump Operation
Pins 7-8: Jumper ON Enables Celsius (°C) temperature display
Pins 7-8: Jumper OFF Enables Fahrenheit (°F) temperature display
