EW-802

EW-802 temperature controller is a small, high-precision, easy-to-operate temperature controller, it adopts rail mouting case, and is equipped with three control outputs, one of which controls the water pump by measuring the temperature difference between the high and low temperature zones. When the temperature difference reaches the set value, the water pump will automatically run for circulation to balance the water temperature of the two zones. One of which controls the heating equipment, when the solar heating fails to reach the set temperature, the heating equipment will start working until the water of the high temperature zone reach the set value. The other controls the water valve, which will be activated when there is a shortage of water in the tank.
