How the coolant heating is heated:
(1) After starting the machine and pressing the start water pump on/off key at the bottom, when the temperature of the aluminium body reaches 90° as shown on our display, the water pump for heating the coolant will be turned on automatically and the coolant will be heated with maximum power. The heating time is about 1 hour and 5 minutes, after reaching the time for heating the coolant it will automatically switch off the coolant heating and resume air heating. The coolant heating function is switched off at any time during the process of heating the coolant, and air heating is automatically restored after switching off. (If you want to heat the coolant faster during the heating process you can close the warm air outlet tee gate).
(2) When we are heating the air in the process of warm air, want to open the coolant heating, but the display shows that the temperature of the aluminium body is higher than 120 °, the program will be based on the temperature of the aluminium body will automatically identify the aluminium body to dissipate the heat below 120 or so will automatically open the coolant heating, to avoid the phenomenon of thermal expansion and contraction.
(3): Air heating and coolant can be heated at the same time, but there will be air heating is not hotter than the air heating alone, this is because the temperature of the aluminium body will be coolant to take away some of the heat, only when the coolant is not turned on heating, air heating will be hotter.
