Solar Controller SRK868V6 Installation and Operation Instructionshttp://www.keracontrols.com 13IMPORTANT NOTE: Do not set the time period that cross over the 24:00 hrs (12 midnight ). The controller may notschedule the timing properly.Note:• The Temperature controlled hot water circulation function has higher priority than the Time controlled hot watercirculation function.• If the Temperature controlled hot water circulation function is deactivated, then the Time controlled hot water circulationfunction is activated automatically.• The location of the sensor T4 should be at least 1.5m (5 Ft) away from the tank in order to prevent undesired operation.3.10 Anti Freeze protectionNote: this function should only be used in systems that do not use anti-freeze liquid.A) If this function is enabled, the solar pump control output (P1) will be switched ON when the temperature of the collectors(T1) falls below the preset ON temperature of the anti-freeze protection.When the collector temperature T1 rises 5 o C (9F) higher than the preset ON temperature of the freeze protection, thecontroller will turn OFF the solar pump output (P1).B) If this function is enabled and the tank temperature (T2) falls below +10o C (+50F), the heating booster output (H1) willbe switched ON automatically and it will be switched OFF when the water temperature (T2) rises above +15o C (59F).To Enable / Disable this function:► Press the “SET ” button once. The freeze protection temperaturesetting will flash.(The default setting is OFF, display: “-- --“ )► Press the “OK” button to enable this function.► Press “▲” “▼” button to adjust the switch-ON temperature of thefreeze protection.Adjustment range: +2o C to +10o C (+36F to +50F).After 6 seconds, the controller will lock-in the settings.► To disable this function, press the “OK” button while the function is enabled. The display will show: “-- --“.This symbol on the display indicates that the high temperature protection (1) is enabled.NOTE: In areas where freezing temperatures occur often, we suggest that a solar system with anti-freeze liquid be usedrather than water as the heat exchange medium.3.11 High temperature protection ( mode 1 )this mode operates in order to prevent overheating of the water in the tank, the controller checks the temperature of thetank on T2 sensor. When T2 rises above +95o C (+203F), the solar pump (P1) is deactivated. When the temperature T2drops below +85o C (+185F), the system returns to normal operation.Note: This function default parameters are permanently preset and cannot be altered by the user.This symbol on the display indicates that the high temperature protection (1) is enabled. |
