Product Features
1.Copper paint spray sealing on welding port/soldering point surface, highly anti-rusting & deeply balancing uneven tension by poor welding.
2.Meticulous heat preservation process. High-quality thermal insulation tape combines with high-density Polyeaster rubber-plastic thermal insulation foam, conducting 360°thermal insulation around components & pipes, heat loss in 24H is ＜4℃ & seals much noise.
3.TWO solders high-temp. welding, fully improving welds’ strength to reduce gas leakage. Mysteriouse flux miraculously improves auxiliary heat conduction, removing oxides, reducing welded surface tension & increasing the area, preventing re-oxidation &＞2-time prolonging pipeline’s life.
4.”Pressure Sensor” takes place of Pressure Gauge, not easy to frost, with “pressure”, “water flow” & more real-time data can indicates in LED screen.

Working Principle
1. In the heat pump, the evaporator coil is exposed to the outside air.
2. The refrigerant enters the evaporator as a cold liquid/gas mixture at low pressure.
3. Heat from the outside air causes the refrigerant to boil into gas.
4. This gas is pumped through to the condenser coiI by a compressor which also increases the refrigerant’s temperature and pressure.
5. The refrigerant is now hotter than the temperature of the water in the tank, so heat flows out, heating up the water in the
tank and condensing the refrigerant back into a liquid.
6. The refrigerant then flows through an expansion valve that allows the pressure and temperature to drop again by the time it reaches the evaporator coil.
7. Once the refrigerant reaches the evaporator coil the cycle is repeated.

SG ready Control logic
When Smart Grid Function is set to “Use”, the logic is as follows:
SG Grid Signal [LDIsg] | EVU Supply Signal [LDIevu] | Smart Grid Command | Smart Grid Display |
0 | 1 | Smart Grid Directive 1 | Display low-peak power consumption icon |
0 | 0 | Smart Grid Directive 2 | Display peak power icon |
1 | 0 | Smart Grid Directive 3 | Indicates free electricity icon |
1 | 1 | Smart Grid Directive 4 | Indicates free electricity icon |
