EW-801A

EW-801A temperature controller is a small, high-precision, easy-to-operate temperature controller, it is equipped with two output controls, 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. The other ouput 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.
