temperature difference value of circulation pump. The setting range is from 5°C to 30°C
with the default value 8°C.
Directions
Q
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.

Q
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.
