SunTouch Motherboard Connections
The SunTouch system motherboard is mounted onto the back of the control panel located in the Power Center.
The motherboard provides the voltage connections to switch the filter pump, heater, auxiliary relays, motorized
valves, and connections for temperature sensors. To access the motherboard, refer to “Accessing the
SunTouch Motherboard,” on page 52.
Equipment Power
• It is recommended to connect the filter pump relay to an independent circuit breaker. Follow
manufactures instructions when installing and testing of ground fault circuit breakers (GFCB) and
interrupters (GFCI).
• The SunTouch Power Center can house a maximum of three power relays. Connect pumps and other
high-voltage equipment to the power relays.
