Hysteresis Description
The limit value of the external sensor is 45°C for factory default (A6), and the value of the external sensor control return difference (A3) is 2. When the temperature rises to 45°C, the relay stops working and will activate a high-temperature production alarm. If the temperature decline to 43°C relay continues to work and the heating alarm will be deactivated. (it can be operated, only when the indoor temperature is lower than the setting temperature).
Sensor Fault Display
Please choose the correct working way of built-in and external sensors, if you choose incorrectly or the sensor fault (breakdown), “E1” or “E2” will be displayed on the LCD screen. The thermostat will then stop heating until the fault is eliminated.
