How to check accumulative thermal energy in solar water controller?

Operation manual of solar water controller SR868C8/SR868C8Q (DKWH) and accumulative thermal energy (KWH) or (MWH) can only be checked after triggering of OHQM thermal energy balance function. Press “+”“-” button can check the value of temperature sensors T1~ T4.

How do I set the water temperature on my solartouch controller?

To set the water target temperature, press the Less (Down arrow) button or More (Up arrow) button to lower or raise the set temperature to the desired level. Nocturnal Cooling: The SolarTouch controller provides automatic nocturnal (nighttime) cooling during night time hours for pools that overheat in hot climates.

How do I install a solar sensor?

Run a two-conductor cable between the sensor and the controller. The maximum sensor cable length is 300 ft (90 m) from the controller enclosure. Mount the sensor on a flat surface, with the same exposure to sun as the solar collectors (next to the collectors is recommended). Do not let the sensor touch the panels. WARNING: DO NOT DRILL HOLE AND

How do I change the settings on my solartouch® controller?

Scroll through menu options. Adjust menu settings. All menu settings are permanently saved and retained even after the unit is power off. During normal operation, when SolarTouch® Controller is displaying Water Temp, Target Temp and Solar Heat ON/OFF setting. Press and release the Enter button to view current Water and Solar Temperature.

How do I calibrate the solar roof sensor?

Use the Up or Down arrow button to adjust the calibration of the sensor. The sensor can be adjusted up to +/-10°. As you adjust the degree off-set value the corresponding temperature will also be adjusted. Note: The solar roof sensor must be 6° higher than the water temperature. The pump must be ON for a few minutes for operation.

How does the solartouch® controller cool the pool/spa?

This allows the air in the solar collectors to be evacuated from the system without damage to the pump. 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.
