split solar system

Description:
SPLIT PRESSURIZED SOLAR WATER HEATER
Working principle:
First, we set 2 temperature differences via controller, T1=Max. Temperature D-value between flowing passage and water in tank, T2=Min. temperature D-value between flowing passage and water in tank,
  1) When the temperature D-value between flowing passage and water reaches the T1, the controller shall start the circulation pump automatically
  2) Circulation pump makes heat-conducting liquid circulate automatically
  3) Heat-conducting liquid transfers heat to water by heat exchanger in the water tank
  4) Case the temperature D-value between flowing passage and water is under the T2, the   circulation pump shall be shut automatically
  5) When we use the water, if the temperature of the water tank does not reach set value, then start the auxiliary heating device
Specification
