Relay connects or disconnects when:
When working mode is set as “Refrigerating",the relay connects if the measuring
temperature is above or equal to the setting temp.value plus the difference value; and relay disconnects when measuring temp.value is below or equal to the setting temp. value.
When working mode is set as Heating",the relay will connect if the measuring temp. value is below or equal to the setting temp.value; the relay will disconnect when the measuring temperature is above or equal to the setting temp. value plus the difference value.
LED displays"HH when temperature is between +99℃~+120℃;LED displays "EE" and system cose the output when sensor error. The controller can restart up or close only when the control output delay time is running out.
Please strictly distinguish the connections of relay, sensor and power. Make sure the relayis not overload.
all the wire connection must be operated under the power off status.
Prohibit to use the controller under the circumstances such as :over moisture, over high temperature, strong electromagnetic interference, strong corrosion
Make sure the voltage confirm to the marking on the machine and the power supply steady. It is advised to keep proper distance between sensor leads and power supply wire to avoid possible interference.
