The SolarTouch
®
Controller can cool the pool/spa by circulating water through the solar
collectors when the solar temperature is at a lower temperature than the pool/spa water
(typically at night). Cooling must be enabled in the Cooling Menu. The default setting is
“Disabled.” To start and stop cooling, adjust the start (default 6°) and stop (default 3°)
temperature differential settings.
Cooling turns ON; when the water temperature is above the target temperature and
the “differential cooling” temperature to Start is met, then cooling will start and the valve
actuator will rotate. After five minutes the Cleaner Pump Relay will turn on.
