Frequently Asked Questions (FAQ)
How do I setup a two-speed pump?
A two-speed pump operates using two relays and one or more circuits. The first relay turns the pump on or
off. Assuming this is a filter pump, this circuit is controlled by the pool and spa circuits or any other circuit that
may be tied to the filter pump (such as circuits with freeze protection, etc.). The second relay (AUX 2)
switches the pump from low speed to high speed. The default condition is low speed. Up to three circuits may
be assigned to trigger the pump to high speed. However, if three relays are being used, two relays must be
located outside the SunTouch enclosure. The SunTouch enclosure which houses two relays. Note: These
circuits do not switch the pump on.
To configure a two-speed pump relay, refer to “Settings Menu: 2-Speed Pump,” on page 29. For relay location
and wiring (see page 53). The 2-Speed pump relay connector is plugged into the AUX 3 output socket on the
SunTouch motherboard.
Can I switch the heater on and change the temperature from the spa?
The heater may be switched on from the spa location using the QuickTouch wireless remote controller
(optional), see page 28 for setup details.
How do I switch on solar heating?
The system must first be configured for solar heating. Go to the “Heat” menu (see page 14) and enable
“Solar” as the heat source. Note: Do not select “Heat Pump” as the solar heating method.
