SR981S/SR982S operation manual of solar pump stationPage 46 of 85►Press “SET” button, “04 oC” flashed, the switch-off temperature difference can be set.►Press “ ” button, to adjust the value of switch-off DT F, adjustable range : 0oC~(On-2 oC), factory setting is 4 oC►Press “ESC” button to exit this setting, or after seconds to exit automatically, parameteris saved automatically.Note: due to different system, maximum 3 temperature differences (DT1o, DT1F), (DT2o,DT2F), (DT3o, DT3F) can be set, setup steps are same above steps.8.4 TEMP Temperature main menuFor solar system, the factory set parameters are for the best operation condition, which isfully integrated into the entire solar system. But these parameters can also be setindividually to cater the special requirements, please carefully observe the operation dataof system components after setting.Note: Parameters that can be set rely on the system design; it means not all theparameters are suitable for all solar systems.Following submenu can be accessed though TEMP main menu.ParagraphTem.Code Function of temperature Adjustable range Factory setFunctionexit tem.8.4.1 EMOF Maximum switch-off temperature of collector (ON+3oC)~200 oC 130 oC8.4.1 EMON Maximum switch-on temperature of collector (OFF-3 oC)~197oC 120 oC8.4.2 CMX Maximum limited temperature of collector(collector cooling function) 90 oC ~180 oC 110 oC 107 oC8.4.3 CMN Low temperature protection of collector 0 oC~90 oC OFF8.4.4 CFR Frost protection temperature of collector -10 oC~10 oC OFF8.4.5 REC Re-cooling temperature of tank OFF8.4.6 SMX1 Maximum temperature of tank 1 2 oC~95 oC 60 oC 58 oC8.4.7 SMX2 Maximum temperature of tank 2 2 oC~95 oC 60 oC 58 oC8.4.8 MAX1Maximum switch-off temperature for heattransfer between tank and heat return (MIN1+2oC)~95 oC 60 oC8.4.9 MIN1Minimum switch-on temperature for heattransfer between tank and heat return 10 oC~(MAX1-2 oC) 30 oC8.4.10 MAX2Maximum switch-off temperature for heattransfer between heat exchanger and tank(MIN2+2 oC)~95oC 60 oC8.4.11 MIN2Minimum switch-on temperature for heattransfer between heat exchanger and tank10 oC~(MAX2-2oC) 30 oC8.4.12 C - F Switch between Celsius and Fahrenheit oC ~oF oC
