Directions for use Operation methods Under various working mode, the operations are as follows: „„ The solar heating mode is as follows: 1 Press the button , then A twinkles, press the button to set the current time, "hour" . 2 Press the button , then B twinkles, press the button to set the current time, "minute" . 3 Press the button again, then A displays "L" and B twinkles; press the button to set temperature difference value of circulation pump. The setting range is from 5°C to 30°C with the default value 8°C. QQDirections  In solar energy heating mode, temperature difference between solar collector output vent and water storage tank is used to control operation of circulation pump through which hot liquid in the solar collector flows into water storage tank and cold liquid in the bottom of water storage tank flows into solar collector for circulation. If temperature at the output vent of solar collector is lower than 120°C temperature of water storage tank is no more than 85°C and the temperature difference is higher than the set temperature difference of circulation pump, then circulation pump starts to work. When temperature difference is lower than 3°C, then circulation pump stops working.  It is suggested that the set temperature difference of circulation pump shall be 15°C in summer and 8°C in winter. „„ The presetted heating mode is as follows: 1 Set the dated time 1. Press the button , then A twinkles, press the button to set the current time, "hour" . 2 Press the button , then B twinkles, press the button to set the current time, "minute" . 3 Set the dated time 2. The setting method is same to setting method of time 1. Repeat the operations in 1 and 2. 4 Press the button again, then B twinkles; press the button to set the dated temperature for electric heating. The setting range is from 30°C to 75°C with the default value 65°C. QQ Directions  After setting the dated time and temperature, the system will heat water to the dated temperature before dated time. When it is the dated time, the system will maintain the temperature for 30 minutes; while the current temperature is 5°C lower than the set temperature, it will start the electric heating. During the heating course of dated time, staged and temporary heating is utilized. Absorb solar energy in priority. When solar heating can not realize dated temperature, start electric heating for supplement. Thus presetted heating needs operation in longer advance. It is normal phenomenon.  If it is intended to date one time, set the two same dated time. Haier solar water heater 11
