SunTouch Pool and Spa Control System Installation and Users Guide

Operating SunTouch in Solar Only Mode

SunTouch Solar Only mode
In “Solar only” mode, you can control your SunTouch solar system to heat your pool and spa. From the control
panel you can set the temperature, and the differential temperature controls for the water up heat up to the set
temperature. After the temperature is reached, the solar system is automatically switched off.
Solar Only auxiliary outputs (Filter pump, booster pump, cleaner and time clock)
Filter pump: In “Solar Only” mode, the Filter pump is controlled externally by the time clock, which ensures
the Filter pump is running before the Booster pump switches on.
Booster pump: To increase water pressure through the collector array, a high voltage booster pump can be
used in addition to the main Filter pump. The Booster pump will switch on at the same time as the Filter pump,
assuming solar heat is available. When using a Booster pump, connect it to the AUX 1 relay in the SunTouch
Power Center. For SunTouch solar booster kit (P/N 520857) information, see page 38.
Pump output on the SunTouch motherboard is on whenever solar heat is available and off whenever
Solar heat is not available
AUX 1/Booster pump is on whenever Solar heat is available and off whenever solar heat is not
available
AUX 2 (Cleaner): The cleaner is off for five minutes when solar heat is detected.
The three actuated solar valves are off whenever solar heat is not available.
SunTouch Pool/Spa Mode
In Pool/Spa mode you can fully automate your pool and spa, pool only or spa only operations. The additional
SunTouch menu features let you create customized schedules for your pool and spa equipment, heat
temperatures, and chlorination settings to switch on and off at a set day and time. For maintenance and service
purposes, the control panel allows manual control of all pool and spa operations. For information about
Pool/Spa mode, see page 9.
